Xss Guard

Stop cross-site scripting before it hits your browser.

XSS Guard detects and neutralizes all three types of XSS attacks — reflected, stored, and DOM-based — the moment they appear. No configuration needed. Install it, and every tab is protected.

What you get:

• Real-time blocking — Malicious scripts are caught and killed before they execute. You see a threat count badge on the icon so you always know what's happening.
• Threat dashboard — A clean, detailed log of every blocked attack: severity, type, payload, timestamp, and domain. Filter, search, and sort to understand your exposure.
• One-click export — Download your threat history as JSON for security audits, bug reports, or your own analysis.
• Site whitelist — Trust specific domains when you need to. Toggle protection on or off per site from the popup.

How it works:

Install XSS Guard. That's it. The extension runs silently in the background, scanning page content against a curated signature database. When it finds an XSS payload, it blocks execution and logs the event. No popups, no interruptions — just a badge count and a dashboard when you want details.

Your data stays with you:

XSS Guard collects nothing. Zero analytics, zero tracking, zero network requests. All threat data lives in your browser's local storage and never leaves your machine. You can clear everything from the dashboard at any time.
