XSS Guard is a free Chrome extension designed to provide real-time protection against cross-site scripting (XSS) attacks, including reflected, stored, and DOM-based threats. The installation process is straightforward, requiring no configuration; once installed, it operates silently in the background, scanning web pages for malicious scripts. Users benefit from immediate blocking of threats, which are logged for review, ensuring that security is maintained without interrupting the browsing experience.

Key features include a threat dashboard that displays detailed logs of each blocked attack, including severity and type, as well as an option for users to whitelist trusted sites. Additionally, users can export their threat history in JSON format for further analysis. Importantly, XSS Guard prioritizes user privacy by not collecting any data, ensuring that all threat information remains securely stored locally.
