Enter a public website hostname to check its live HTTPS certificate. ScoutLab verifies the public destination before connecting and reports a bounded set of certificate facts without signing you up or storing the result.
Check the rest of your public website security signals
This utility checks one part of the picture. ThreatScout's broader free scan also reviews HTTPS, security headers, DNS and email-protection signals.
The checker performs a verified HTTPS connection to the public website and returns certificate details that are useful when checking renewal and transport configuration.
The effective public hostname reached after safe same-domain redirects.
Certificate issuer, validity dates and days remaining until expiry.
The negotiated TLS protocol when the verified connection succeeds.
Whether the nominated hostname redirected to another hostname on the same registrable domain.
What a valid SSL certificate does not prove
HTTPS encrypts traffic between a visitor and the website and gives the browser a way to validate the hostname. A perfectly valid certificate can still sit in front of outdated software, weak administration controls or vulnerable application code.
Use certificate checking as one transport-security signal, not as a complete website security assessment.
Why certificate expiry should be monitored
Certificate renewal is normally automated, but automation can fail after hosting, DNS or platform changes. An expired certificate can stop visitors reaching a site normally and can interrupt integrations that expect valid TLS.
Ongoing external monitoring is useful where you want visibility into certificate and configuration drift instead of relying on a one-off check.
ScoutLab's checker verifies a live HTTPS connection to the public hostname and reports bounded certificate facts such as issuer, validity dates, days remaining and the negotiated TLS protocol when available.
Does a valid SSL certificate mean a website is secure?
No. A valid certificate protects the encrypted connection and validates the hostname. It does not test application code, accounts, patching, malware or every vulnerability on the website.
Can I check an internal server or IP address?
No. This public tool accepts public hostnames only and deliberately rejects literal IP addresses and non-public destinations.
