Zscaler Integrates SquareX to Deliver Stronger Browser Security Protections

Zscaler announced the acquisition of SquareX (closed February 5, 2026) to integrate lightweight security extensions into standard browsers (e.g., Chrome and Edge), enabling Zero Trust protections for unmanaged and BYOD devices without requiring VDI, legacy VPNs, or a proprietary enterprise browser. The move aims to secure SaaS and private applications, perform device posture checks without full OS agents, and reinforce Zscaler’s position in enterprise cloud security.
