Overview

Inspect the real TLS certificate chain of every site against your regex patterns; flag matches on the toolbar icon.

ChainGuard is a Chrome extension that passively reads the certificate of each site you visit, checks it against regex patterns you define, and flags matches on the toolbar icon, plus optional desktop notifications and a searchable history of everything it scanned. Everything runs locally.
