Google Safe Browsing

Google's real-time blocklist of phishing and malware URLs. The most widely deployed URL-reputation feed in the world.

Safe Browsing is the database Chrome, Firefox, and Safari consult when you click a link. If the URL is on the list, the browser shows a red warning page.

It's a high-signal feed — Google manually validates a lot of submissions — but it's not exhaustive. New phishing pages can take hours or days to land in the database, and that gap is exactly what attackers exploit.

PhishGuard checks every scanned URL against the Safe Browsing v4 API as one of its sources.
