Frequently Asked Questions

What metrics does the DNS & SSL checker audit?

It evaluates DNS records (A, AAAA, MX, TXT, NS, CNAME), SSL/TLS validity period, issuing Certificate Authority, and essential OWASP security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options).

Is the checker protected against SSRF attacks?

Yes. A strict SSRF shield verifies resolved IP addresses and rejects loopback (127.0.0.1), private RFC 1918 subnets, and cloud metadata endpoints.
