SquareX Reviews for 2025

What is SquareX?

SquareX is a cybersecurity software platform that provides real-time protection against online threats directly within the browser. It focuses on isolating risky web activities such as file downloads, link clicks, and website visits into secure, disposable cloud environments called “Isolation Pods.” This ensures that malicious files, phishing pages, or infected sites cannot reach the user’s device or corporate network.

The software works seamlessly through a browser extension and cloud infrastructure. Instead of blocking access, SquareX allows users to interact with any link or document safely by containing potential threats in virtual sandboxes. This approach enhances both user productivity and security, removing the trade-off between protection and usability.

SquareX also offers visibility and analytics for security teams. Admins can monitor sessions, detect risky behaviors, and enforce organization-wide security policies without intrusive agents or performance degradation. Designed for modern, remote-first environments, it helps businesses defend against malware, ransomware, and credential theft from web-based attacks.
