How to use this toolMy WorkPrivacy and accuracy
!SSL and HTTP Security Checker limitationsHTTPS and header checks originate from the hosted service and are observations, not a complete security audit.Expand disclaimerCollapse disclaimer⌄

Certificate details may depend on an external cached assessment. Redirects, load balancers, geographic routing and changing responses can affect what is observed. Missing or present headers alone do not prove that a website is insecure or secure; appropriate policies depend on the application.

Important: Do not rely on this result alone for purchasing, configuration, security, safety, compliance, contractual or fault-diagnosis decisions. Results can be incomplete, delayed, misleading or wrong. Verify important findings with the relevant provider, manufacturer documentation and an appropriate independent test or qualified professional.
