What does Zscaler do?

ZS · Plain-English company overview

A stock is a share of ownership in a company. Owning one means you own a small piece of that business.

In the company's own words, from Item 1 (Business) of its latest annual report (Form 10-K) filed with the SEC on 2026-09-03.

We are the cybersecurity platform for the AI era. We empower our customers with the cybersecurity solutions necessary to protect their enterprises, drive growth and outpace competitors where success depends on securely adopting the technologies required to operate and compete effectively in an AI world. We were founded in 2007, based on a vision that, with the broad adoption of SaaS applications, the internet would become the new corporate network, the cloud would become the new data center and perimeter-based security would fail to protect users, applications and data. As AI redefines how businesses operate, and powerful AI-enabled cyberthreats proliferate, enterprises must now adopt a zero trust approach to security. We deliver a comprehensive, cloud-native zero trust platform that minimizes the attack surface of an enterprise and eliminates lateral threat movement, enabling security at the scale and speed of AI. As a result, we believe we are the only cybersecurity platform capable of protecting enterprises in the most complex and consequential threat landscape in history.

The traditional model of enterprise security built around hub-and-spoke networks, firewalls and virtual private networks, or VPNs, was designed to protect a fixed perimeter. With rapid and increasing cloud adoption, workforce mobility and the emergence of an autonomous agentic workforce, traditional perimeter security fails to completely secure the modern enterprise, is prohibitively expensive and delivers poor user experience. These outdated yet widely-deployed tools are preventing enterprises from safely embracing the digital transformation that is necessary to compete today.
