# Modernizing Security and Compliance: LichtBlick SE Secures Multi-Team Kubernetes Deployments with Calico Enterprise Microsegmentation

We chose Calico because it satisfied our stringent requirements for microsegmentation and enhanced visibility of network traffic, which are crucial for our audit needs.

LichtBlick SE, a leading German green energy provider, was undergoing a significant IT modernization by rapidly adopting Kubernetes to host critical applications for its numerous engineering teams.

Facing stringent audit requirements and lacking granular separation in their previous clusters, the company needed to implement robust microsegmentation and strictly control egress traffic to sensitive external services. They also required simplified, self-service policy management.

By implementing Calico Enterprise with Egress Gateways and a custom self-service policy tool, LichtBlick successfully achieved production microsegmentation. This enabled safe, scalable multi-team deployments and simplified their security posture to meet compliance.
