Normal TLS primarily authenticates the server to the client.

With mutual TLS, both sides present certificates.

Mutual Authentication

This is particularly useful for:

  • APIs
  • Microservices
  • Machine-to-machine communication
  • Zero Trust architectures
  • AI agents and automated services

Instead of relying entirely on passwords or API keys, each workload can have a cryptographic identity.
