"SquareX offers what it has dubbed a "Browser Detection and Response (BDR)" solution that converts any web browser into an enterprise-grade secure browser, providing the same functionality as dedicated enterprise browsers without cumbersome change management. SquareX claims that its browser extension effectively manages threats like malicious extensions, phishing, genAI data leakage, insider threats, and more, directly within the browser environment, reducing the enterprise attack surface without compromising user experience."
"With the technology provided by SquareX, Zscaler says it will be able to extend 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. SquareX raised $20 million in a Series A funding round led by SYN Ventures in April 2025."
