Using an unordered list, summarize the following article with between 4 and 8 key points. Zscaler (ZS +7.44%) is one of the world’s leading cybersecurity companies. Its zero-trust architecture was designed to protect businesses from the most serious cyber threats, including those powered by advanced technologies like artificial intelligence (AI).
The company released its operating results for its fiscal 2026 third quarter (ended April 30) after the market closed on Tuesday, May 26, and despite a relatively strong report, its stock plummeted by 31% the next day. The company announced that two senior members of its sales department had left, so management subsequently issued very conservative revenue guidance for fiscal 2027.
Zscaler stock is now down 42% in 2026, but could this be a long-term buying opportunity for investors?

Zero-trust security was built for the AI revolution
A zero-trust cybersecurity architecture treats every attempted connection to a corporate network as hostile, meaning that nobody receives automatic access. Zscaler’s Zero Trust Exchange verifies each user not only by their login credentials, but also by analyzing the device they are using and their location. This increases the odds of stopping an imposter.
But the Zero Trust Exchange goes even further. It only connects employees to the specific applications they need to complete their jobs, so even if a malicious actor does bypass the identity security layer, they won’t have unrestricted access to the entire corporate network. In essence, this minimizes the damage from a successful breach.
In 2024, Zscaler expanded its focus to include “branches,” which can be anything from a warehouse to a factory to a retail store. This culminated in a product called Zero Trust Branch, which isolates those assets from the rest of the corporate network, so even if one of them is breached, the hacker can’t compromise the rest of the organization.
Zscaler is now extending the Zero Trust Exchange to include AI agents, allowing enterprises to choose which specific applications or data files agents can access in order to complete tasks. This eliminates a hacker’s ability to gain access to all of an organization’s valuable assets by hijacking a single agent.
These new products tie Zscaler’s “Zero Trust Everywhere” philosophy together. Hackers are increasingly using technologies like AI to launch sophisticated attacks at machine speed, meaning they can uncover vulnerabilities faster than ever before. As a result, a zero-trust architecture at the identity and application layers is no longer enough — it has to be the standard across the entire organization.
Solid revenue growth, but weak forward guidance
Zscaler ended the fiscal 2026 third quarter with $3.5 billion in annual recurring revenue (ARR), which was a 25% increase from the year-ago period. That matched the 25% growth rate the company delivered in the second quarter three months earlier, suggesting there hasn’t been a slowdown in momentum.

Nevertheless, Wall Street is nervous about the potential impact of Zscaler losing two senior sales employees during the quarter, particularly because the company offered very few details about their departures when probed by analysts. However, CFO Kevin Rubin did say the sales team could face disruptions in the near term as it adjusts to new leaders.
Some of that disruption was reflected in management’s forward guidance, which suggests Zscaler’s ARR growth could slow to just 16% in fiscal 2027. That is the key reason why its stock plummeted following the release of the third-quarter report. However, it’s too early to know whether the conservative guidance will be accurate, and Zscaler does have a history of beating management’s expectations.
After all, it appears that enterprises are buying into Zscaler’s Zero Trust Everywhere philosophy at a blistering pace. At the end of the third quarter, the company had 700 customers in this category, which more than tripled from the year-ago period. I personally wouldn’t bet against any company producing that kind of growth in its core product portfolio.
Zscaler stock is near the cheapest level in its history
Zscaler stock is trading at a price-to-sales (P/S) ratio of 6.6, which is close to the lowest level since its initial public offering (IPO) in 2018. Plus, it’s significantly cheaper than competitors Palo Alto Networks and CrowdStrike:

From that perspective, Zscaler stock looks like a good value right now. I’m not suggesting it will achieve a similar P/S to CrowdStrike, because that company has a deeper product portfolio that targets a broader addressable market, so its long-term opportunity is larger. Besides, I happen to think a P/S ratio of over 30 is extremely expensive, particularly in a hyper-competitive industry like cybersecurity. However, even if Zscaler closes some of the valuation gap, its stock could deliver solid upside from here.
In summary, it wouldn’t be wise to invest too aggressively in Zscaler stock until there is more clarity about its true growth trajectory next year, but I think demand will only increase for zero-trust architectures in the coming years, which should support strong long-term returns.
