Catch what breaks on your client sites before the email arrives.·guardr.io

Guardr is a security scanning and uptime monitoring tool for websites, aimed at agencies, freelance developers and solo developers managing client sites. It externally scans TLS/SSL, security headers, DNS security, exposed files, cookie security and client-side JavaScript for leaked API keys, producing an A-F security grade with plain-English remediation steps. It also monitors uptime 24/7 from 3 global regions and can alert users when a security grade drops, a certificate is about to expire, or a site goes down. Guardr offers a single dashboard to monitor multiple sites, with API access, PDF reports and a WordPress plugin.
