Why SSL monitoring matters

An expired SSL certificate instantly breaks trust with your visitors. Modern browsers display red warnings, payment providers block transactions, and emails may even be rejected if STARTTLS fails. For a small business, that can mean lost sales, reputation damage, and unnecessary support tickets.

With endpnts.io, SSL checks run automatically so you always know when certificates are close to expiry, misconfigured, or missing important fields. You get notified before customers notice, giving you time to renew or fix the problem.

What we check

Expiry monitoring: alerts when certificates are approaching expiry (configurable lead time).
Chain validation: verify that the full trust chain is present and correct.
Hostname matching: ensure the certificate covers the domains you expect.
Signature & algorithm checks: flag weak or deprecated crypto.
Unexpected changes: notify when a certificate is replaced by an unrecognised authority.

Problems we prevent

“This site is not secure” browser warnings from expired certs.
Payment or API integrations failing due to mismatched CN/SAN values.
Trust errors from missing intermediate certificates.
Unexpected certificate swaps — often a sign of proxy misconfiguration or attack.
Weakened security from outdated signature algorithms.

SSL checks at a glance

Clear validation results with practical impact explained.

Check	Validation	Impact if broken
Expiry	Warn when certs near expiry (e.g. 30, 14, 7 days)	Site becomes inaccessible, browsers block traffic
Chain	Confirm intermediate and root certs are valid	Trust errors across major browsers and devices
Hostname	Verify CN/SAN covers target domain	APIs and apps reject TLS connections
Algorithm	Check signature & key length security	Weakened encryption; compliance violations
Unexpected change	Diff against last-known certificate	Indicates misconfig or possible MITM
