Can you explain the differences between TLS and mTLS protocols?

TLS (Transport Layer Security) is a protocol that provides a secure connection between a client and a server, where the server typically presents its certificate for authentication.

mTLS (mutual TLS) is an extension of TLS where authentication occurs on both sides: both the server and the client present their certificates. This increases security because the server verifies the authenticity of the client, not just the other way around.

An example of using mTLS is internal API services within a company, where it is important to ensure that requests come from trusted clients.
