How to: Why use mTLS?
mTLS helps ensure that the traffic is secure and trusted in both directions between a client and server. This provides an additional layer of security for users who log in to an organization's network or applications. It also verifies connections with client devices that do not follow a login process, such as Internet of Things (IoT) devices.

Nowadays, mTLS is commonly used by microservices or distributed systems in a [zero trust security model](https://en.wikipedia.org/wiki/Zero_trust_security_model) to verify each other.
