SSL / TLS

The cryptographic protocol securing HTTPS connections — TLS 1.3 is current; SSL is deprecated terminology still used colloquially.

Definition

In long form.

TLS (Transport Layer Security) replaced SSL (Secure Sockets Layer) in 1999 — every "SSL certificate" is now technically a TLS certificate. TLS 1.3, ratified in 2018, is the current standard; TLS 1.0 and 1.1 are deprecated and rejected by modern browsers. Free certificates are available via Let's Encrypt and ZeroSSL with 90-day auto-renewal. EV (Extended Validation) certificates exist but no longer get a special UI in browsers — most teams use DV (Domain Validation) since the trust signal disappeared.

In context

We don't sell or manage certificates as a separate line item — every modern hosting platform (Vercel, Netlify, Cloudflare) issues and renews certificates automatically.
