SafeGuard

SafeGuard Secure is a lightweight browser protection extension that keeps you safe from dangerous websites before you even land on them.

Three layers of protection — all free, all real-time:

SafeGuard checks every site you visit against multiple threat databases simultaneously. If a threat is detected, you're intercepted before the page loads.

Heuristic Analysis — instantly catches typosquatting, brand impersonation, suspicious URL patterns, and known phishing structures without any network call

Google Safe Browsing — cross-references every URL against Google's continuously updated database of malware and phishing sites

PhishTank — a community-powered phishing database that catches threats Google hasn't flagged yet
