Jay Chaudhry — Chief Executive Officer, Chairman, and Founder
Thank you, Bill. We had a very strong quarter to close out a spectacular year. In Q4, we delivered growth of 57% in revenue, and 70% in billings as customers embraced our expanded cloud platform to accelerate their digital transformation. Let me share a few highlights of fiscal ’21. Our full-year revenue grew 56%, to $673 million, and billings grew 70% to reach $934 million. We are seeing revenue growth across all the verticals, customer segments and geographies. 51% of revenue was from outside the United States.
I’m very excited to see our ARR approaching $1 billion, and pleased to note that our new annualized bookings and new logo acquisition accelerated throughout the year. All product pillars of our platform saw strong demand. Notably, ZPA revenue surpassed $100 million in fiscal ’21, growing 166% year-over-year. Increased cyber security risk and accelerating digital transformation has increased the need for our Zero Trust architecture. We are uniquely positioned to reduce business risk and make businesses agile and more competitive. We are the only cloud provider at scale with a proxy-based architecture to deliver true Zero Trust security. Firewall and VPN-based castle-and-moat security connects users to the corporate network which facilitates lateral movement of threats, increasing cyber risks.
Zscaler connects users only to applications, not to the network, a core principle of Zero Trust architecture, that reduces ransomware attacks and other cyber risks. Built from the start, to enforce policy at the edge as advocated by the SASE framework, the Zscaler Cloud spans 150 data centers with 5-9s of availability, providing fast and secure access to all applications whether in your data center or in a multi-cloud environment. Because of these architectural advances and our proven ability to scale, the Zscaler Zero Trust Exchange has become the foundation for big sole transformation. With a record number of seven-figure ACV deals in Q4, we now have over 200 customers with greater than $1 million in ARR, over 5,600 enterprises, including 35% of the Fortune 500 trust Zscaler to secure their transformation journey. While the average Net Promoter Score of SaaS companies is 30, Zscaler’s is 74, which is to 2.5 times higher, proof of the value what Zscaler delivers.
Now, I would like to discuss three market segments where we made significant progress during the quarter in the fiscal year. First, the financial services sector has become our top vertical, as these companies are embracing the cloud and Office 365. Let me highlight three new customer wins in Q4 for the purchase of ZIA and ZPA together.
First is a global bank that’s adopting a Zero Trust strategy to protect over 100,000 employees with our high-end ZIA and ZPA bundles. They’ve purchased every module we offer in the ZIA pillar, including firewall, sandbox, CASB, DLP and browser isolation. Fast user experience and enhanced cyber security were the key factors for our win.
Our second new logo win is a Fortune 500 asset management company that purchased ZIA and ZPA to secure over 30,000 employees. And third is a Fortune 500 insurance company that purchased ZIA and ZPA for 26,000 employees to enable work from anywhere. These wins illustrate when companies are ready to embrace the cloud, Zscaler is the only cloud-native, multi-tenant platform that meets their needs. With security as a major requirement, these financial services customers only considered a proxy architecture that can provide SSL inspection at scale and rejected firewall-based architecture. We now count eight of the top 10 global banks and seven of the top 10 insurance companies outside of China as our customers.
Next, let me highlight our progress in the enterprise market segment, which includes organizations with 2,000 to 6,000 employees. We started focusing on the segment at the start of fiscal ’21, and the results have exceeded our expectations. This segment includes over 12,000 organizations, representing $8 billion of our serviceable market for user protection. Deal sizes in this segment are growing as customers adopt more of our platform.
I’m excited to see our first seven-figure upsell win in our enterprise segment where the customer is buying all four pillars of our platform, ZIA, ZPA, and ZDX for 6,000 users and ZCP workload segmentation for almost 3,000 servers. Our ARR with this customer now exceeds $1.5 million, validating a significant opportunity in this market segment. To further penetrate this segment, we are developing targeted marketing programs, significantly growing our sales team and doubling down on our Summit Partner Program to recruit and enable channel partners to drive further sales leverage.
Finally, we continue to invest to capture a large federal opportunity with a sizable Fed sales team and the highest FedRAMP certification, we count well over 100 government agencies and federal integrators as customers. In Q4 alone, we added over 20 new federal customers, including four with over $1 million in annual contract value, each purchasing ZIA and ZPA together.
Driven by the President’s recent Executive Order, we are seeing increased interest in our Zero Trust Exchange across all levels of the government. We are among a select group of companies chosen by NIST, a national standards body to run a pilot program in support of the Executive Order. We are excited about this opportunity to help our country dramatically improve our security posture, while significantly reducing legacy IT costs.
Next, let me highlight our technology innovations and emerging products which are expanding our opportunity. We started with a highly scalable, multi-tenant globally distributed cloud, capable of providing inline inspection of Internet and SaaS traffic with ZIA, and securing access to private applications with ZPA. Over the past year, we extended our platform to protect cloud workloads and to manage digital user experience.
We are very excited about the early traction of our emerging products, the next growth engines for us. Our emerging products contributed high-single digits percentage of a new and upsell business in fiscal ’21, which is well ahead of our expectations. ZDX is the fastest-growing solution in our history and a natural complement to ZIA and ZPA. With a single lightweight endpoint agent, it is frictionless to turn on ZDX to provide end-to-end visibility to help resolve performance issues for every Zscaler user.
In Q4, one of our largest ZDX deals came from a Fortune 500 tech company, that purchased the entire ZIA portfolio, as well as ZPA and ZDX for all 60,000 employees to support work from anywhere while embracing Zero Trust architecture. We were pleasantly surprised to see so many large enterprises adopt ZDX so rapidly. Other notable ZDX wins include a Fortune 500 pharma company for 70,000 users, a Fortune 50 energy company for 55,000 users, a Fortune 500 European bank for 39,000 users, and an industrial and manufacturing company for 28,000 users, and a healthcare company for 25,000 users. I believe that every ZIA and ZPA customer will embrace ZDX as user experience is one of the highest priorities for a CIO.
We are receiving very positive feedback from customers. A Fortune 600 healthcare executive indicated ZDX contributed to an 18 point gain in employee net promoter score for their IT service desk in two quarters. After having disrupted perimeter based security with our Zero Trust Exchange for users, our next big opportunity is to bring Zero Trust to workloads with Zscaler Cloud Protection, or ZCP.
Every organization is building their applications in the cloud, and we’ll look to implement Zero Trust security to protect workloads. Our Zero Trust Exchange securely connects workloads to workloads and process to process using business policies, eliminating the need for traditional networks and associated cyber risks. Solutions within our ZCP pillar include. workload posture which includes CSPM and CIEM ensures proper configuration and enforces least privileged access for multi-cloud environments. Workload Communication powered by ZIA and ZPA technology secures app to app and cloud to cloud communication and Workload Segmentation achieves micro-segmentation without legacy network segmentation.
We have over 300 ZCP customers and are seeing increasingly strong interest from new and existing customers. Let me highlight a few ZCP wins during Q4. An existing ZIA and ZPA customer in the consumer goods sector with over 100,000 employees, purchased Workload Communication for 25,000 workloads, and Workload Segmentation for 10,000 workloads. This customer has a large server environment on a traditional network, implementing our Zero Trust for workloads to reduce their cyber risk by minimizing lateral threat movement while securing their app migration to the cloud.
We are also landing new logos with ZCP. For example, we landed a Fortune 500 professional services company, where ZCP was the main driver. This customer purchased Workload Communication for 6,000 workloads, Workload Segmentation for 500 workloads, as well as the entire ZIA bundle for 40,000 employees. Our team collaborated with CrowdStrike, our technology partner and a Global SI, our channel partner for this deal.
Let me conclude some parts on our vision and strategy. We envision a world in which the exchange of information is always secure and seamless. In today’s hyper-connected digital world, our Zero Trust Exchange secures any to any connectivity for users, applications, workloads and IoT and OT systems regardless of their location.
At our Analyst Day in January, we laid out our audacious goal of serving 200 million users and 100 million workloads. In order to achieve this goal, we are focused on attracting and developing talent and creating a culture of excellence. We hired over 1,100 employees over the past year and enabled them to be productive and successful, all during the pandemic. We are investing in our people through learning initiatives and building a culture where a global and diverse workforce can deliver excellence powering our customer success.
Our employees are engaged and completely aligned to our mission. On our last employee survey, 96% of employees understand and believe in the strategic direction of the company. I’m proud that we are recognized as a Great Place to Work in the 2021 Glassdoor ratings. We are focused on driving broad adoption of all four pillars of our platform. The breadth and depth of our platform is resonating with customers and they’re purchasing our higher-end bundles to consolidate their security and networking point products. I believe Zscaler is a go-to platform for vendor consolidation, cost savings, increased user productivity, and better cyber protection.
As we demonstrated over the last 12 months, we built a sophisticated go-to-market machine that delivers business value and measurable outcomes at the CXO level. I’m extremely proud of our go-to-market team and how we executed our sales strategy this year. Even with significant growth in our sales force, sales productivity has increased over the prior year, exceeding our expectations. Our Summit Partner channel program consists of hundreds of cloud focus resellers, system integrators and service providers that are contributing to our deal win and increasing sales leverage. As our market share reputation and brand awareness continue to strengthen, a growing number of cloud and SaaS providers are integrating with our platform, further strengthening our strategic position with our joint customers. Our expanding ecosystem is contributing to our sales velocity and broadening our reach.
I believe we are on the right track to capture a material share of our $72 billion serviceable market. We also see additional opportunities to bring Zero Trust to IoT and OT systems. Moreover, 5G which pushes computing further to the edge opens up additional opportunities for Zscaler. To pursue these markets, we have a two-pronged innovation strategy. One, investing aggressively in internal R&D and scaling our world class engineering organization which continues to rapidly deliver new products and features. We recently opened a new R&D hub in Israel and are expanding our R&D centers across the US, India, Canada and Spain.
Two, making highly targeted acquisitions to enhance our platform and shrink time to market. During fiscal ’21, we completed two acquisitions. Trustdome strengthens our ZCP pillar and positions us better to pursue our shift-left strategy. And SmokeScreen enhances our active defense capabilities with honeypot technology. Through internal innovation and highly targeted acquisition, we will further expand our leadership in the SASE and Zero Trust security markets. In summary, with all these drivers and innovations ahead of us, you can see why we are very excited about our future.
Now, I would like to turn over the call to Remo for our financial results.
Remo E. Canessa — Chief Financial Officer
Thank you, Jay. As Jay mentioned, we are pleased with the results for the fourth quarter and full-year 2021. Revenue for the quarter was $197 million, up 12% sequentially and 57% year-over-year. ZPA product revenue was 17% of total revenue. From a geographic perspective, we had broad strength across our three major regions. Americas represented 51% of revenue, EMEA was 38%, and APJ was 11%. For the full year, revenue was $673 million, up 56% year-over-year. This was an acceleration from the 42% growth we delivered in fiscal 2020.
Our total calculated billings grew 70% year-over-year to $332 million, with billing duration in the middle of our 10-month to 14-month range. We’re also pleased that year-over-year growth in short-term billings accelerated to 71% in the fourth quarter from 61% in the previous quarter. Our strong billings performance was driven by a record number of new seven-figure annualized contract value deals in the quarter as we sold more of our platform offering. We saw a strong growth in our top five verticals, finance, manufacturing, services, health care, and technology. Remaining performance obligations or RPO were $1.553 billion as of July 31, up 98% from one year ago. The current RPO is 49% of the total RPO.
Looking at our pillars, ZPA was 27% of our total new and upsell business in fiscal 2021. Emerging products, which include ZDX and ZCP are tracking ahead of our expectations and contributed high-single digits of our total new and upsell. We are seeing strong customer interest and we expect emerging products to contribute low teens percentage of our total new and upsell business in fiscal 2022. The adoption of our emerging products is pacing ahead of ZTA in its early years. We have a large opportunity with all our pillars, and we will continue to expand our portfolio to strengthen our leadership position in the zero trust security market.
Our strong customer retention and ability to upsell the broader platform have resulted in a consistently high-dollar-based net retention rate, which was 128% compared to 126% last quarter and 120% a year ago. As we have highlighted, this metric will vary quarter to quarter, while good for our business, our increased success selling bigger bundles, selling multiple pillars from the start and faster upsells within a year can reduce our dollar-based net retention rate in the future. Considering these factors, we feel that 128% is outstanding.
We have a strong base of large enterprise customers, which provides us with a significant opportunity to upsell our broader platform. We had 202 customers with ARR greater than $1 million, up 87% from 108 in the prior year. We also had 1,480 customers with ARR greater than $100,000, which compares with 973 customers last year.
Our new customer adds accelerated in fiscal ’21. We organically added approximately 1,000 new logos in fiscal ’21 excluding acquisitions, and we ended the year with over 5,600 customers. Expanding our field engagement with small enterprises with 2,000 to 6,000 employees and the increased investments in our partner program are contributing to higher new customer growth.
Turning to the rest of our Q4 financial performance. Total gross margin of 80% declined by 1 percentage point quarter-over-quarter and improved by 1 percentage point year-over-year. Our total operating expenses increased 15% sequentially and 60% year-over-year to $138 million. Operating expenses as a percentage of revenue increased by 1 percentage point from 69% a year ago to 70% in the quarter primarily due to increased hiring and higher compensation expenses as well as $2 million in expenses related to Trustdome and SmokeScreen operations. Operating margin was 10%, and free cash flow margin was 14%. We ended the quarter with over $1.5 billion in cash, cash equivalents and short-term investments.
Now moving on to guidance. As a reminder, these numbers are all non-GAAP, which excludes stock-based compensation expenses and related payroll taxes, amortization of debt discount and amortization of intangible assets. For the first quarter of fiscal 2022, we expect revenue in the range of $210 million to $212 million, reflecting a year-over-year growth of 47% to 49%. Gross margins of 79%. I would like to remind investors that a number of our emerging products including ZDX, workload segmentation and CSPM will initially have lower gross margins than our core products because we are more focused on time to market and growth than optimizing them for gross margins.
Operating profit in the range of $18 million to $19 million, other income of $400,000, net of interest payments on senior convertible notes, income taxes of $1.2 million, earnings per share of approximately $0.12, assuming 148 million fully diluted shares. For the full-year fiscal 2022, we expect revenue in the range of $940 million to $950 million, or year-over-year growth of 40% to 41%. Calculated billings in the range of $1.23 billion to $1.25 billion, or year-over-year growth of 32% to 34%. We expect our first half mix to be approximately 42% of our full-year billings, which is in line with the average of the last three to four years. Operating profit in the range of $85 million to $90 million, earnings per share in the range of $0.52 to $0.56, assuming approximately 149 million to 150 million fully diluted shares. Please note that our share count guidance now includes dilution from our convertible debentures.
We have a capped call with a strike price of $246.76. Every $10 increase in our stock price above the strike price will add 250,000 to 300,000 shares to our fully diluted share count. For your modeling purposes, I would like to discuss the anticipated T&E and M&A impact to fiscal 2022 operating expenses. In fiscal 2021, we saw a 280 basis point benefit to margins from lower T&E compared to fiscal 2020. With plans for in-person meetings and events in the second half of this year, including sales conferences in Q3, and ZenithLive in Q4, we expect T&E as a percentage of revenue to be approximately 250 basis points to 300 basis points higher in fiscal 2022 as compared to fiscal 2021.
As mentioned previously, the recent acquisitions of Trustdome and SmokeScreen are expected to have an immaterial impact on revenue in fiscal 2022. We expect to incur approximately $13 million to $15 million in operating expenses to further invest in these products and incorporate their technologies into our platform. This is incorporated into our guidance.
Let me conclude with comments on our investment framework. We will balance growth and profitability based on how our business is growing. At our Analyst Day with consensus estimates at that time reflecting approximately 30% revenue CAGR, we outlined our target of achieving 20% to 22% operating margins in fiscal 2024, which implied 300 basis points of margin expansion per year. Since then, we delivered outstanding results with revenue growth exceeding our expectations.
If we continue to have high growth and strong unit economics, we will prioritize investing in the business, which should lead to lower than 300 basis points of margin expansion per year. To that point, our fiscal 2022 guidance of 40% to 41% revenue growth and 9% to 9.5% operating margins reflects approximately 150 basis points to 200 basis points of margin expansion after adjusting for the increased T&E and M&A expenses.
We remain confident of reaching 20% to 22% operating margins in the long term, but growth will continue to take priority considering our strong business momentum. With a huge market opportunity and customers increasingly adopting the broader platform, we’re committed to investing aggressively in our Company.
Operator, you may now open the call for questions.
Questions and Answers:
Operator
Thank you. [Operator Instructions] Our first question comes from Alex Henderson with Needham. You may proceed with your question.
Alex Henderson — Needham — Analyst
Great. Thank you very much. As we’re looking out into the new year, I was hoping you could talk a bit about your thoughts on the type of expansion you’re planning relative to the sales capacity. You’ve been extremely aggressive over the last year. In fact, as I understand it, increased your targets 3 times over the course of the year. Certainly, the environment is extremely robust. Can you talk about where you’re going as we go into the new fiscal year? Thanks.
Remo E. Canessa — Chief Financial Officer
I’ll start with that Alex, and Jay can come in. You’re right, I mean — so the thing that we called out in the call is this, we’re seeing strong momentum for our business, and particularly, in the second half. And you’re absolutely correct. We did increase our field quota sales reps by number in fiscal ’21 versus fiscal ’20. As we go forward, we’ll be making continued investments on our sales organization as well as marketing and also channel. So that’s only a piece of it, and again we will be increasing the number of headcount with our field quota sales reps in fiscal ’22 versus fiscal ’21. But more broadly speaking, the opportunity is still big.
We are going to continue to invest throughout the Company to really position ourselves to move forward and really be substantial company that’s operating efficiently. That’s across all areas, R&D, G&A, our cloud. When I started with Zscaler, we’re doing about 35 billion transactions a day, we are upwards, I don’t know what the number is now, but I know it’s well north of 160 billion transactions per day. It is critical if you’re a cloud company like Zscaler to provide a reliable service that customers can rely on to ensure they are operating efficiently and securely. So our focus is going forward is going to be broad throughout the company, but we continue to invest in sales and marketing and we’ll increase our field rep sales headcount more in fiscal ’22 versus fiscal ’21.
Jay Chaudhry — Chief Executive Officer, Chairman, and Founder
Remo well said. I don’t think I need to add a whole lot more. We are hitting on all cylinders and very excited.
Alex Henderson — Needham — Analyst
Thanks.
Operator
Thank you. Our next question comes from Matt Hedberg with RBC. You may proceed with your question.
Matt Swanson — RBC — Analyst
Yeah. Thank you for taking the question. This is Matt Swanson on for Matt. If I could just dive in a little bit more to those federal opportunities. Great color today on the call, Jay. But when we’re thinking about that zero-trust directive with unique visibility, both into the federal space with 100 customers and then obviously as a zero trust leader. What do you think the gap is right now in the current federal environment to achieving a zero-trust framework? And then in any sense, you can give us some kind of the magnitude and the duration of the opportunity suppose three months from now that mandate became mandatory for all federal environments with the zero trust, how big is that gap?
Jay Chaudhry — Chief Executive Officer, Chairman, and Founder
So if you think of where the federal market is, it’s largely today doing network security. It’s largely castle-and-moat depending upon firewalls, VPNs and the like. The good thing is that Biden Administration has recognized that zero trust architecture has to be done. So it’s great to see that that EO is focused on implementing zero-trust. And look, where we stand today, yes, we start investing in federal market about three and a half years ago and got all the certifications that are needed. And we also have the right architecture and we’ve built the sizable team.
We already have pretty good business, but we are barely scratching the surface of the federal market. I think a lot of thing has to do with education. Good thing is that EOs and some of the new meetings that Biden Administration is having with high-profiled CEOs and the like is raising visibility in the space. We are participating in some of these new pilots. All in all, we are excited but we also know that some of these federal deals take their own time.
Matt Swanson — RBC — Analyst
Thank you.
Operator
Thank you. Our next question comes from Keith Bachman with Bank of Montreal. You may proceed with your question.
Keith Bachman — Bank of Montreal — Analyst
Yes. Thanks very much. I wanted to ask a little bit about the net retention rate. It was very strong this quarter, but you seem to be signaling that there may be some tension on the number. But I was wondering if you could comment on how investors should be thinking about the net retention rate as we lookout? In particular, I did want to reference some of the information you provided at the Analyst Day, where you talked about significant expansion on the annual price per user, both in the user protection category and the workload protection category, as well as just seat growth. So I’m just — I’m a little bit surprised to hear you almost down — I guess, downplayed that 128 number. But if you could just talk a little bit about how investors should think about that over the next fiscal year? Thank you.
Jay Chaudhry — Chief Executive Officer, Chairman, and Founder
I’ll start then Remo can add on. I think, our comments on net retention rate have been consistent since we went public. And here is the real thing. If I were a one-product company, then it matters new logo offset all those things. We have such a big platform that’s growing rapidly. We have also internal debates; should we really pay sales rep more for new logo versus upsell. The answer is we really want to grow the overall new ACV whether it’s coming from upsell or it’s coming from new logo.
So the message is not to really say downplay net retention rate. The message is the net retention rate by itself is not a good indicator. What we are doing is good. We are proud of 128. I’ll be proud of 125 too because if I can sell a bigger platform upfront, I’m okay with a lower NRR. That’s a message. We are happy. We’re bullish. But this metrics by itself is not the best thing as the leading indicator.
Remo E. Canessa — Chief Financial Officer
I’ll follow on with that. Jay is absolutely 100% correct. As we talked about on prior calls, the only time we understand the importance of net retention rate is because of basically our compensation structure, which we pay the same renewal and upsell, we really don’t look at it. And so, you know, we have projections what we’re going to do during the quarter, so we really look at it at the end of the quarter. Now having said that, as you take a look at what we’re — what we talked about at the Analyst Day, and you’re absolutely right, Keith, with the opportunity to sell at a higher price point and we talked about for the users for 5,000 users, we expect to have basically a price point about $145 per user. We are seeing that. So — and so we are seeing basically companies that are buying ZIA — the ZIA add-on, ZTE and ZDX, we’re seeing those type of dollar amounts.
So the other point which we haven’t talked about, the average revenue per user is increasing substantially, and so what we’re seeing is that we’re seeing customers buy our broader platform. We are seeing customers who were actually buying ZCP and not buying the user protection initially. So all indications are that things are going well. The net retention rate, the positive impacts are the new products. If you take a look at the number of Global 2000 companies have both ZIA and ZPA, it’s 44%. So I wouldn’t take our comments, related to net retention rate that it’s going to go down. We don’t — we really just don’t focus on it. And we’re just trying to really condition our investors to really think about the broader platform we have, both new and upsell and basically our top line growth.
Keith Bachman — Bank of Montreal — Analyst
Perfect. Many thanks.
Operator
Thank you. Our next question comes from Mike Walkley with Canaccord Genuity. You may proceed with your question.
Mike Walkley — Canaccord Genuity — Analyst
Great. Thank you. Congratulations on the strong quarter and year. Maybe just building on that last answer a little bit, and you’ve highlighted the enterprise segment targeting 2,000 to 6,000 employees as your fastest-growing segment. Did these smaller customers with faster sales cycle, do they have a similar land as your larger customers, and have a long runway for upsell? Or they landing with a large amount of your platform?
Remo E. Canessa — Chief Financial Officer
Overall, the cost today whether as new enterprise segment or a larger one, more and more, they are buying bigger and bigger platform. It is true that enterprises probably 2K to 6K tend to go a little bigger from the start. But it’s good — it’s a shorter sales cycle, and these guys have the same risk of ransomware attacks unlike the others. So we are actually surprised to see how much traction we’re getting in this segment in the past few quarters since we focused on.
See, the focus also on enterprise is through our summit program we put in place a year ago. So we’re seeing strong traction through our summit program. And the summit program is geared towards those customers net 2,000 to 6,000 range. So very positive feedback, very positive results as Jay mentioned over this past year. We’re excited that this is an opportunity, and as Jay mentioned, it’s our fastest-growing segment and we’re excited about that opportunity.
Mike Walkley — Canaccord Genuity — Analyst
Great. Thank you.
Operator
Thank you. Our next question comes from Jonathan Ruykhaver with Baird. You may proceed with your question.
Jonathan Ruykhaver — Baird — Analyst
Yeah. Hi, guys, congratulations on the strong quarter.
Jay Chaudhry — Chief Executive Officer, Chairman, and Founder
Thank you.
Jonathan Ruykhaver — Baird — Analyst
Jay, this is probably more for you. But when you look at the publicly traded firewall vendors, they are clearly experiencing very strong demand trends for their virtual firewalls for cloud applications, cloud environments. And I’m just wondering how do you reconcile that with your comments around the benefits of a proxy? I mean doesn’t it seem to suggest that there could be different approaches, different architectures to securing cloud?
Jay Chaudhry — Chief Executive Officer, Chairman, and Founder
I think about this quite a bit. If you recall, three, four years ago, we were asked this question quite a bit and this is being asked. Why are these proxy vendors like [indecipherable] still posting good numbers. I was telling them that we are barely making an impact,. A lot of traffic was still going through those proxy appliances in the data center. If you look at the local breakout business that’s done out there, we are the primary vendor software. Others, yes, have come out there, but the majority of the enterprise traffic still goes through hub-and-spoke network. it still goes through a data center. It’s still going through those firewalls.
As your traffic year-over-year goes up by 33%, you’ll end up getting more data center devices whether it’s firewalls or other stuff. I think then you get to a certain level, whereas traffic shifts significantly, the spend will shift. That’s my personal view. So not surprised that why legacy devices like firewalls are still growing, so I think it’s a matter of time.

Thank you. Our next question comes from Gray Powell with BTIG. You may proceed with your question.
Gray Powell — BTIG — Analyst
Okay, great. Thanks for taking the questions, and congratulations on the strong results. So yeah I’m curious like how are you thinking about the potential to increase pricing on renewals, particularly now that cloud-based network security is more mainstream and the sales process is less evangelical than say three or four years ago.
Remo E. Canessa — Chief Financial Officer
I want to be looking at increasing renewal price. Is that what the question is?
Gray Powell — BTIG — Analyst
Yes, exactly.
Remo E. Canessa — Chief Financial Officer
Right. Our biggest increase in prices coming fall selling bigger bundles, okay. And there is some increase in price on each module but the pace at which we are expanding our portfolio is quite significant. And as customers see the value and because we show business value, the increase in price for customer from ACV point of view becomes a natural thing, I think if you — if we want to compete on price, to compete on say I’m a better firewall than those firewalls then it gets hard.
We don’t really compete to replace a given firewall or proxy. We are enabler of secured digital transformation. The sale is often driven by the CIO to Head of Infrastructure to Head of security. When they look at the long-term money, we can save them, to replace all of these legacy firewall, security and networking devices, the ROI is very impressive to justify our price becomes a lot easier. So value-based business, value-based pricing is what we have advocated.
Gray Powell — BTIG — Analyst
Yeah, I think so. And maybe I could have asked the question better. I guess my understanding was like four or five years ago, you had to be more aggressive because — I mean like SASE wasn’t even a term back then. People were less comfortable having security in the cloud. Today it’s more mainstream. So I thought, that’ll give you more ability to increase prices. That was my question.
Jay Chaudhry — Chief Executive Officer, Chairman, and Founder
Yeah. I would think, yes, we have done some price increases on the original products, but big increases come from adding a lot more modules. If you look at the time of IPO, three and a half years ago, it was largely secure web gateway with a few things. It was largely a business bundle sale, or professional bundle. Today, what we are selling is very different than what we sold three years ago, very different than what we sold one year ago.
The SASE market that Gartner talks about is a very expensive market. It includes everything you need to have at what used to be the network security level. And looking at even Zscaler Private Access, it’s not just a VPN replacement. It eliminates the need for entire inbound DMC. That’s a big thing. So as we expand the platform, it further differentiates us, it further consolidates pulling products. We love the fact that the market is moving so fast, so rapidly, and they’re innovating so fast, that’s why we think it will be very hard for some of the me-too’s to come from behind and catch up with us.
Gray Powell — BTIG — Analyst
Understood. Okay, that’s very helpful. Thank you.

Thank you. Our next question comes from Hamza Fodderwala with Morgan Stanley. You may proceed with your question.
Hamza Fodderwala — Morgan Stanley — Analyst
Hey, guys, thanks for taking my question. Jay, perhaps the question for you. So last year, Zscaler saw a huge uptick in demand with the Zscaler Private Access solution. To what extent are those customers who may have bought perhaps smaller licenses or perhaps temporary licenses last year are coming back now as they renew and signing larger perhaps ELAs as you guys progress through the next few quarters?
Jay Chaudhry — Chief Executive Officer, Chairman, and Founder
So last year when customers needed to do buy ZPA, if I shared with investors during our earnings calls that there are very few — if any temporary licenses, okay, a very few actually, one-year deals, most of the deals were done with us on a multi-year basis. And when they bought ZPA during the pandemic, most of the time it was not for a subset of users. It was really done for most of the users. So from our point of view, the sales that were made last year were really made for long-term. Is that impacting us in the short term, not really. But having said that, are we selling more and more ZPA to every ZIA customers, absolutely. Now, the market thinks that ZIA and ZPA together should be bought because once you have both of them together, you can access any application from anywhere.
In fact, Gartner has further clarifies SASE’s positioning, it’s kind of interesting. SASE was a good loose framework, but it was confusing to some degree because it kind of got interpreted as is the network and SD-WAN and security must be with a single vendor, not true. In fact, Gartner has a new position paper that came out about a month or two ago, which basically said, the security part of SASE is Secure Service Edge, SSE, and with a new MQ that will come out — magic quadrant that will come out in X months. And the second part that decoupled the network part of it they’re calling it wireless LAN edge, and that’s where the SD-WAN part fits there.
We have the most comprehensive offering of what Gartner is calling now, secured service edge. That’s really what gives us differentiation, that allows us to compete and win and charge good prices, and really make sure ZIAs and ZPAs get sold to every user, not just a subset of users.

Thanks. Your next question comes from Shaul Eyal with Cowen & Company. You may proceed with your question.
Shaul Eyal — Cowen & Company — Analyst
Thank you. Hi, good afternoon, and congrats on the results and guidance. Jay, want to go back to the typical competitive landscape question. I know we’ve been kind of discussing that as of late, but just wanted to check if there is anything new or anyone new that has come to mind as of late, some of that you have been seeing in a more pronounced way operating within your markets? Thank you for that.
Jay Chaudhry — Chief Executive Officer, Chairman, and Founder
Yeah. See, overall if you ask me, has the landscape changed significantly in terms of players out there, not really. The biggest change in the landscape is in the workload posture market in the cloud protection area. When it comes to SASE, ZIA and ZPA competition, there’s not a whole lot. Now there is a fair amount of noise that’s coming out there because when legacy network security vendors are getting disrupted, they must do something to make noise, so they really don’t become extinct. That’s why — I mean we do hear every so often when customer says, oh, I am doing my firewall, VPN in the cloud that is zero-trust, right?
Now, zero-trust and firewall or VPN and the cloud don’t go together. So if you ask me, one of the main things we need to make sure is we clarify that you can’t build a zero-trust architecture with firewalls and VPNs. The good thing is smart folks like Mist and Gartner are helping that area. But the momentum is building, business is doing good, and we want to keep on investing aggressively, as Remo said to take a big share of this increasing and evolving sizable market. And the last point, I want to make is the number of modules we saw sell today on average versus a year ago — versus three years ago has increased significantly which is very good. It’s no longer that status quo siloed firewall are secure web gateway market.
Did that make sense?
Shaul Eyal — Cowen & Company — Analyst

Thank you. Our next question comes from Sterling Auty with J.P. Morgan. You may proceed with your question.
Sterling Auty — J.P. Morgan — Analyst
Yeah. Thanks. Hi guys. Hey, Remo, I wanted to ask a nitpicky question. Obviously, the results are fantastic, well above guidance and expectation. but given that current RPOs accelerated for three straight quarters, short-term deferred revenue accelerated, billings calculated remained at 70%, why would revenue actually ticked down a couple of percent? Why wouldn’t it tick up?
Remo E. Canessa — Chief Financial Officer
Sterling, you know me pretty well, I think, for 20 years. Our philosophy related to guidance is to be prudent, and we’re continuing to be prudent with our guidance. Everything you called out is 100% correct. But what I’ve tried to do with Zscaler since I’ve come here is basically, I don’t want to look back. I want to look forward. I want to give ourselves the ability to really run the business. So you know, [Speech Overlap] guidance.
Sterling Auty — J.P. Morgan — Analyst
I was asking about the current quarter, the quarter you just reported, the 56 and change versus [Speech Overlap]
Remo E. Canessa — Chief Financial Officer
I got it. I got it. I’m sorry.
Sterling Auty — J.P. Morgan — Analyst
Yeah. So something that may have impacted conversion.
Remo E. Canessa — Chief Financial Officer
Okay. I got it. I’m sorry. No. I’ve got it. Thank you. So it’s really linearity-based. And if you take a look at it, in Q4 of ’20, last year related to the COVID impact that we had, we had strong billings growth in basically the first part of the quarter. This Q4 ’21 went more normalized, so that is what impacted — primarily impacted the revenue of growing 57% in Q4.
Now, when you take a look at Q3, ’20 versus Q3, ’21, just the opposite effect occurred with COVID. In Q3 of ’20, what happened was that the world basically, I don’t want to say stopped, really slowed down in the March timeframe even early April. So the linearity in Q3 last year was lower where Q3 of ’21 this year, the linearity was more normalized. So we had 60% revenue growth in Q3 ’21 versus Q3 ’20, and we had 57% revenue growth in Q4 ’21 versus Q4 ’20, directly related to the impact of COVID.
Sterling Auty — J.P. Morgan — Analyst
Thank you.
Remo E. Canessa — Chief Financial Officer
In addition, Sterling, there is one other element, which is basically when you take a look at the large number of deals that we have and we called out the million-dollar type deals. A lot of those deals have ramps, so with those ramps, you’re not going to get the full revenue in that current quarter. That’s a smaller part of it, but that is a part of it, so the majority of it is related to linearity.
Sterling Auty — J.P. Morgan — Analyst
Remo, thank you. Appreciate it.
Remo E. Canessa — Chief Financial Officer

Thank you. Our next question comes from Brian Essex with Goldman Sachs. You may proceed with your question.
Brian Essex — Goldman Sachs — Analyst
Yeah. Good afternoon, and thank you for taking the question. Jay, I’d love it if you could characterize the nature of enterprise adoption on your platform, primarily from the perspective of enabling meaningful change, digital transformation and a shift in architecture versus maybe more evolving with a large enterprise, enabling them to get started down that journey. Is there any difference this year versus last year? And maybe if you could characterize the environment of basically enabling a big architectural shift as opposed to enabling, I guess, a slower migration towards your technology platform.
Jay Chaudhry — Chief Executive Officer, Chairman, and Founder
Brian, great question. So bigger shift got caused by COVID. Before COVID, enterprises used to think about adopting Zscaler with network transformation, branches being broken into local breakout and the like. With COVID since network got out of the loop, enterprise said, I’m going to download this micro-agent and I’m ready to go with ZIA to external applications, ZPA to internal applications. That mindset is still there. I love it because one, when you don’t have to deal with the network, your sales and deployments go much faster.
So our Phase 1 these days is get everyone turn on from wherever they are. Phase 2 ends up being let’s do local breakout for network transformation. And then Phase 3 ends up being, let’s look at the cloud workload protection and the like. So it is evolving and it’s evolving where things are moving at a faster pace.
Brian Essex — Goldman Sachs — Analyst
Got it. That’s helpful context. Thank you very much.

Thank you. Our next question comes from Erik Suppiger with JMP Securities. You may proceed with your question.
Erik Suppiger — JMP Securities — Analyst
Yeah. Thanks for taking the question, and congrats on a very strong quarter. Hey, Remo, I think you had mentioned that pricing is around $145 for organization of 5,000 users. Can you remind us where that was about a year ago? And then also you talked about some accounts that have been buying the full breadth of modules for ZIA. What kind of discount do you give to that customer when they buy the full breadth of modules?
Jay Chaudhry — Chief Executive Officer, Chairman, and Founder
Yeah. We’re not — first of all, I don’t want to get into how much we’re discounting customers but that’s more competitive. When you take a look at those 5,000 users, the $145, that’s how much that we’re seeing customers of 5,000 users paying for the full complement of our offerings. Now with that, ZDX is new, okay. ZIA, which is $25 of that $145. Largely the ZIA add-on are new related to browser isolation, DLP and CASB out of the band, and that’s around $30. If a customer buys the full transformation level, which is we have three bundles pro-business transformation, it’s about $45 and ZTA is about $45 also. Where has it gone from a price per user basis overall year-over-year, we’re seeing between 35% and 40% increased price per user on a year-over-year basis.
So that’s kind of put the context of what we’re seeing. And again that increase in price per user is related to customers buying more of our platform and also expanding their business with this.
Erik Suppiger — JMP Securities — Analyst
And do you think that 35% to 40%, is that sustainable going into next year given the accelerating expansion of portfolio?
Jay Chaudhry — Chief Executive Officer, Chairman, and Founder
I don’t want to comment related to the expansion because I don’t want to make those type of forward-looking statements. But if you step back and take a look at the importance of the platform that we’re selling and also more customers buying more of our platform, in addition to that, with the new products, we talked about our emerging products represent high-single-digit of our new and upsell business. As we go forward, we’re seeing the emerging products represent low teens basically of our new and upsell business in fiscal ’22.
As the market evolves and as the comments were made, we’re not in the same place where we were four years ago, or three years ago, even two years ago. And so my expectation is that we’ll continue to see increased pricing. But I don’t want to quantify it, and we’ll just report on it as we go forward.
Erik Suppiger — JMP Securities — Analyst
That’s great. Thank you.

Thank you. Our last question comes from Rob Owens with Piper Sandler. You may proceed with your questions.
Justin Roach — Piper Sandler — Analyst
Hey, guys, this is Justin on for Rob. I just want to double-click on the commentary around the federal business. I know you guys usually put it around mid-single digits of new ACV in prior quarters. Any sense that this was higher in the current quarter, and then maybe some assumptions for the federal business in the pipeline in the guidance for next year. Thanks.
Remo E. Canessa — Chief Financial Officer
I’ll start it Jay. So federal in the current quarter was mid-to-higher single digits in Q4. As Jay talked about, the federal business for us with the Executive Order from President Biden, as well as you know federal embracing zero trust, and also our investment with our certifications and our field organization that we have in federal, we feel very good about it. Now, how is it going to play through in fiscal ’22? We’ll see. We feel there’s a very big opportunity and we also feel that it could be a substantial portion of our business. But it takes time with federal, but we’re well-positioned.
And with that, I’ll turn it back to Jay.
Jay Chaudhry — Chief Executive Officer, Chairman, and Founder
Yeah I think pipeline is good. We have all the certifications, right architecture that federal government recognizes, requiring zero trust architecture, we are investing and pretty positive and confident.
