Can you explain what Mutual TLS is and how it ensures the security of connections?

Mutual TLS (mTLS) is an extension of standard TLS where authentication occurs on both sides: client and server. In regular TLS, the server provides its certificate for the client to verify its authenticity. In mTLS, the client also provides its certificate, which the server verifies.

This provides mutual authentication, increasing connection security, as both parties are confident in each other's identity. This approach is often used in corporate networks and microservices architectures to protect data and prevent unauthorized access.
