Frequently asked questions

What exactly do you scan?

We scan your website's TLS/SSL configuration, security headers (CSP, HSTS, X-Frame-Options, etc.), DNS security (DNSSEC, CAA records), and check for exposed sensitive files like .git or .env. All checks are non-intrusive and only examine publicly visible configurations.

Is this a vulnerability scanner?

No. Guardr monitors security configuration and uptime — the publicly visible settings that form your first line of defense. We don't do penetration testing, code analysis, or CVE scanning.

How is this different from SecurityHeaders.com?

Free tools give you a one-time snapshot. Guardr monitors continuously, alerts you when something changes, tracks history over time, and provides step-by-step fixes. Plus uptime monitoring included.

Do I need to install anything?

No. Guardr scans your website externally — no agents, no code changes, no server access required. Just enter your domain and we do the rest.

Can I use this for client websites?

Absolutely! Our Pro and Agency plans are built for managing multiple client sites with branded reports, team access, and client portals.
