Looking back on cybersecurity stocks’ Q4 earnings, we examine this quarter’s best and worst performers, including Zscaler (NASDAQ: ZS) and its peers.

Cybersecurity continues to be one of the fastest-growing segments within software for good reason. Almost every company is slowly finding itself becoming a technology company and facing rising cybersecurity risks. Businesses are accelerating adoption of cloud-based software, moving data and applications into the cloud to save costs while improving performance. This migration has opened them to a multitude of new threats, like employees accessing data via their smartphone while on an open network, or logging into a web-based interface from a laptop in a new location.

The 9 cybersecurity stocks we track reported a mixed Q4. As a group, revenues beat analysts’ consensus estimates by 1.5% while next quarter’s revenue guidance was in line.

Amidst this news, share prices of the companies have had a rough stretch. On average, they are down 8% since the latest earnings results.

Zscaler (NASDAQ: ZS)

Pioneering the "zero trust" approach that has fundamentally changed enterprise network security, Zscaler (NASDAQ: ZS) provides a cloud-based security platform that connects users, devices, and applications securely without traditional network-based security hardware.

Zscaler reported revenues of $815.8 million, up 25.9% year on year. This print exceeded analysts’ expectations by 2.1%. Overall, it was a strong quarter for the company with EPS guidance for next quarter exceeding analysts’ expectations and full-year EPS guidance exceeding analysts’ expectations.

“We believe Zscaler is the cybersecurity platform for the AI age - our in-line Zero Trust platform is uniquely architected to secure the unprecedented speed and scale of AI and agentic workflows. Organizations racing to adopt AI are looking to us to provide the security solution they trust, and we're just scratching the surface of this massive future growth opportunity,” said Jay Chaudhry, CEO, Chairman and Founder of Zscaler.

Zscaler pulled off the fastest revenue growth of the whole group. Investor expectations, however, were likely higher than Wall Street’s published projections, leaving some wishing for even better results (analysts’ consensus estimates are those published by big banks and advisory firms, not the investors who make buy and sell decisions). The stock is down 13.2% since reporting and currently trades at $145.25.

Market Update

Late in 2025 into early 2026, there was hand wringing around artificial intelligence. For software companies, the fear was that AI would erode pricing power and compress margins as new tools made it easier to replicate what once required expensive enterprise platforms. Crypto investors had their own version of the same anxiety: if AI agents could trade, allocate capital, and manage wallets autonomously, what exactly was the long-term value of today’s crypto infrastructure?

These concerns triggered a noticeable rotation away from these sectors and into safer havens. But markets rarely dwell on one narrative for long. Spring 2026 came, and the focus shifted abruptly from technological disruption to geopolitical risk. The US’ conflict with Iran became the dominant driver of market psychology, and when geopolitics takes center stage, the script changes quickly. Investors stop debating growth rates and start worrying about oil supply, inflation, and global stability.
