Case Study: AFA Försäkring achieves micro-segmentation and prevents lateral movement with Illumio Core

AFA Försäkring Protects Against Lateral Movement with Illumio Core

AFA Försäkring, a major Swedish insurer serving more than 4.8 million people and managing roughly 195 billion (≈4.8B USD) in assets, needed stronger segmentation to protect sensitive data and meet GDPR requirements. Their legacy approach of hundreds of VLANs and firewall rules was complex, time‑consuming, and ineffective at stopping lateral movement inside the network.

AFA deployed Illumio Core and, within two months, used its real‑time application dependency map to identify high‑value applications, define strategy, and implement micro‑segmentation across ~600 workloads. The solution delivered live east‑west visibility, safe policy testing, faster allowlisting, and much lower operational overhead—significantly improving security, efficiency, and compliance readiness.
