All you need to know: TLS vs. SSL

SSL (Secure Socket Layer) and TLS (Transport Layer Security) are both cryptographic protocols that encrypt and authenticate data traveling from the client (i.e. your device that is requesting a website) to a server, machine or application

SSL is TLS’ predecessor. SSL was first released to the public in 1995. However, it had many vulnerabilities, so it was replaced by SSL v3.0 a year later. The latter wasn’t perfect either, so TLS was introduced in 1999. Most devices and browsers have now moved to TLS v1.2.
