What is mTLS?
Mutual TLS — both client and server verify certificates. Foundation of Zero Trust communication.
Why It Matters
mTLS appears in production engineering decisions around security, identity, reliability, and platform operations. Understanding the term helps you read architecture diagrams, debug incidents, and choose safer defaults.
When you see mTLS in a course, article, architecture review, or incident write-up, connect it to the system boundary it protects, the team that owns it, and the failure mode it is meant to reduce.
