What it means in plain language
SSL is a historical name for encryption technology, also commonly used to refer to modern TLS-based certificates and connections.
Where it genuinely helps
SSL is the historic predecessor of TLS, although the name is still commonly used for an HTTPS certificate.
What to decide before acting
Separate certificate, protocol and server configuration in documentation so obsolete SSL versions are not implied.
How to tell whether it works
Check trust chain, domain names, expiry, automated renewal and secure cipher configuration.
