What is it

Redirect Checker lets the Utillica server inspect DNS, email authentication, redirects, TLS, and HTTP security headers and summarize them for operational checks. Localhost, private IPs, link-local, and metadata hosts are blocked for SSRF protection. Results are references, not security guarantees.

FAQ

Can it check internal networks or localhost?

No. Localhost, private IP, link-local, and metadata hosts are blocked to reduce abuse and SSRF risk.

Does pass guarantee security?

No. pass/warn/fail is a reference judgment based on currently visible signals, not a security audit.
