SquareX Enterprise is a browser security platform that provides Browser Detection and Response (BDR) capabilities for enterprise environments. The platform is now part of Zscaler following an acquisition. The solution operates as a browser-native security tool that works across any browser and device. It provides enterprise browser security and browser-based Data Loss Prevention (DLP) functionality to protect organizations from web-based threats. SquareX addresses security gaps that traditional security tools like EDR/XDR and Secure Web Gateways (SWGs) have with browser extensions and web-based attacks. The platform monitors and responds to threats that occur within the browser environment, including malicious browser extensions and browser hijacking attacks. The company has conducted security research on browser vulnerabilities, including discoveries related to Chrome extension security risks, Syncjacking attacks, and bypasses in Secure Web Gateways. Their research has been featured in major cybersecurity publications and presented at industry conferences including Black Hat, DEF CON, and RSA Conference. SquareX Enterprise provides real-time threat detection and response capabilities at the browser level, offering visibility and control over browser-based activities that traditional cloud-based security solutions cannot adequately monitor.
