BreachGuard

Monitor and protect against data breaches in real-time. Hard blocks known malicious domains and warns on suspicious activity.

BreachGuard watches what you browse and stops known-bad destinations before they load. It hard-blocks malicious domains from curated threat feeds, flags risky or suspicious sites, and shows a clear interstitial when something is stopped. On the current tab you get an at-a-glance safe / warn / block status, plus counts for threats and trackers blocked and when feeds last updated.
