Free tool
Free Website Health Checker
Check your website’s security certificate, HTTPS setup, security headers, speed and domain expiry in seconds. No signup.
This tool makes a few ordinary public requests to the website you enter, the same as any visitor would, and reads its public certificate and domain registration. The domain is sent to Netoja’s server to run the check; we do not store it. Results are practical guidance, not a full security audit or penetration test. Domain expiry is not available for every domain ending (for example .ie). To build overall statistics we count only an anonymous score range, never your answers, domain or any personal data.
