SquareX

SquareX protects users from browser-based threats such as phishing and session hijacking with technology that focuses on securing the browser itself. Its Browser Detection and Response technology is designed to detect and stop threats as they occur within active browser sessions. The platform monitors browser-level behavior to identify credential theft, malicious scripts, account takeover attempts and advanced phishing techniques in real time, instead of relying solely on URL reputation or network inspection. The company delivers its protection through a lightweight browser extension that works with browsers such as Chrome and Edge, as opposed to endpoint agents or a separate corporate browser, to allow organizations to turn existing browsers into secure, enterprise-grade environments. SquareX also offers isolated and disposable browser sessions that contain risks when users interact with suspicious links or files. The company's technology defers to a cloud-based, temporary environment that prevents malware or data leakage from reaching the local device to reduce the impact of zero-day or unpatched threats while keeping workflows largely uninterrupted.
