mTLS
Mutual TLS
Definition
mTLS extends standard TLS by requiring both the client and server to present and validate certificates, providing two-way authentication. In microservice architectures, mTLS ensures that only authorized services communicate with each other, preventing lateral movement by compromised workloads.
Service meshes like Istio and Linkerd automate mTLS certificate issuance and rotation transparently.
Can this ship? Are we exposed? Can you prove it?
Every CISO is asking these three questions. We answer them with facts, not guesses, from repository to runtime.
