What is TLS?

TLS (Transport Layer Security) is a standardized cryptographic protocol that protects data transfer in Internet communications. 

This protocol is used to encrypt communications between systems. Access to web pages and other types of communications, including e-mail, is usually done securely with TLS. 

TLS aims to ensure secure and private data exchange, protecting users against attacks and data exfiltration. 

TLS replaces the old SSL and is one of the most secure cryptographic standards. Currently, TLS 1.2 and TLS 1.3 are mainly used.
