If your security strategy relies solely on "being inside the VPC," you’re one compromised container away from a total breach.

I just published Part 2 of my Service Mesh series: mTLS & Zero Trust.

In this installment, I break down how to move away from blunt VPC firewalls and implement cryptographically verified identities for Cloud Run using SPIFFE and Managed mTLS.

We’re diving into the "Zero Trust" requirements of a production mesh:

✅ The Identity Framework: Why SPIFFE IDs and short-lived certificates are the only way to scale trust across regional boundaries.  ✅ Automated Handshakes: How to leverage Google’s Certificate Authority Service (CAS) for zero-touch certificate rotation—no manual key management required.  ✅ L7 Authorization: Moving beyond ports to enforce fine-grained Method and Path-based policies. Stop a DELETE request at the sidecar level before it ever hits your application logic. ✅ The Migration Blueprint: My GDE-level guide for moving from Permissive to Strict mTLS mode on a live system with zero downtime.

In a modern serverless architecture, an IP address is just a temporary label. If you want true security, you need a signature.
