GDPR compliance in a service mesh is not optional. It’s survival. Modern distributed systems hold sensitive data in motion. Every request between microservices is a potential exposure. A breach can happen anywhere in that flow. A GDPR-compliant service mesh locks those flows down, enforces policy at scale, and gives you proof when regulators come knocking.
A service mesh routes, secures, and observes all traffic between services. But it’s not enough to encrypt data and call it compliant. GDPR demands more: encryption in transit and at rest, access control with least privilege, fine-grained audit trails, and the ability to forget user data on demand. A proper GDPR-ready service mesh automates these protections and ensures they can't be bypassed.
Encryption must be mutual TLS with automatic certificate rotation across the entire mesh. Authorization policies must respond to identity, not just network location. Data minimization must be enforced at the edge, filtering out unnecessary personal information before it flows deeper into the system. Monitoring must log events with context, but never store personal data in the logs themselves.
