Zscaler Acquires SquareX to Advance Zero Trust Browser Security for the AI Era

Zscaler, Inc. (NASDAQ: ZS), the leader in cloud security, today announced it has acquired SquareX, to further extend Zero Trust capabilities into the browser for the AI era. This acquisition will help redefine browser security, allowing organizations to embed lightweight extensions into any browser, providing increased security and eliminating the need for third-party browsers.

Organizations have been using vulnerability-prone Remote Access Virtual Private Networks (VPN) or expensive Virtual Desktop Infrastructure (VDI) to extend productivity to unmanaged, third-party devices. Zscaler disrupted the market with the introduction of Zscaler Private Access^TM (ZPA^TM), leading a global shift away from traditional VPNs and toward a true Zero Trust architecture. By utilizing a lightweight agent, Zscaler continues to deliver unmatched security and critical device posture checks to tens of millions of users, setting the standard for secure enterprise connectivity.

As organizations' needs evolve and cyberthreats increase, Zscaler is advancing its Zero Trust leadership to address the emerging requirements of the modern, distributed enterprise. With SquareX, Zscaler will extend the same level of uncompromising security to unmanaged devices, enabling organizations to secure users within their preferred browser - such as Google Chrome and Microsoft Edge - without the need for a full agent or the limitations of a separate, third-party browser.

“Enterprises have historically relied on legacy VPNs and VDIs, but these technologies are fundamentally flawed and laden with security risks,” said Jay Chaudhry, CEO, Chairman, and Founder of Zscaler. “With SquareX, Zscaler is deepening our Zero Trust Exchange^TM Platform’s capabilities in standard browsers, such as Google Chrome or Microsoft Edge, to stop threats without having to deploy a third-party enterprise browser. Zscaler continues to set the standard as we evolve into an increasingly powerful platform for global enterprise security.”

“By integrating with Zscaler, we will enable organizations to secure SaaS and private applications across any device - managed or BYOD - without compromising productivity,” said Vivek Ramachandran, founder of SquareX. “This approach allows IT leaders to replace expensive, insecure legacy access tools with precise Zero Trust policies that protect data and AI interactions based on an organization’s specific risk profile.”

The acquisition closed on February 5, 2026. Terms of the transaction have not been disclosed.
