SiteGuard
A consumer browser companion that translates enterprise-grade vulnerability intelligence into plain-English warnings about risky websites, data leaks, sketchy extensions, and phishing — so everyday users benefit from the same AI-driven safety nets Chrome is now using internally.
Non-technical internet users worried about scams, account takeovers, and data leaks
- Real-time risk score for every site visited with a plain-English reason
- Password-leak scanner that flags accounts exposed in known breaches
- Sketchy-extension detector that rates installed add-ons and recommends removal
- Phishing-page blocker with one-click reporting to a shared threat list
