SSL check
What does an SSL certificate checker check?
TLS covers certificate validity, expiry, chain of trust and protocol strength in one PatchPings security scan.
Chain of trust
Whether intermediates are served correctly so browsers and mobile clients do not fail while desktops pass.
TLS strength & expiry
Protocol support, HSTS signals where present, and how many days remain before renewal becomes an outage.
An SSL certificate checker should answer three questions: is the cert valid for this host, is the chain complete, and will it expire before you notice?
