Nemesis

Persistent Security builds Nemesis, a Breach and Attack Simulation (BAS) platform whose attacks learn. While traditional BAS tools execute static playbooks, our AI Operator is trained with reinforcement learning against real customer environments, so it adapts to every defence it encounters. Nemesis runs continuous, MITRE ATT&CK-mapped attack campaigns through agents deployed on each distinct configuration (golden image) rather than on every endpoint, making rollout fast and operational overhead low.

Outputs are board-ready: which controls held, which didn't, what to fix first. We are EU-native, headquartered in Belgium, with DORA and NIS2 alignment built in. Today we serve customers in financial services, critical infrastructure, defence, and healthcare across Europe, with 30+ MSSP partners covering DACH, BeNeLux and the Nordics.
