Cilium Transparent Encryption with IPSec and WireGuard

Encryption is required for many compliance frameworks. Kubernetes doesn’t natively offer pod-to-pod encryption. To offer encryption capabilities, it’s often required to implement it directly into your applications or deploy a Service Mesh. Both options add complexity and operational headaches.

Cilium actually provides two options to encrypt traffic between Cilium-managed endpoints: IPsec and WireGuard. In this lab, you will be installing and testing both features and will get to experience how easy it is to encrypt data in transit with Cilium.
