What it is

TLS 1.2 (RFC 5246) and TLS 1.3 (RFC 8446) are the supported transport-security versions. Older TLS 1.0/1.1 have known weaknesses and are formally deprecated.

Why it matters

Browsers throw warnings on TLS <1.2; some clients refuse outright. PCI-DSS 3.2 and major frameworks already mandate 1.2 minimum.

Who it applies to

Every HTTPS endpoint.
