Capsule Security fine-tunes Nvidia Nemotron models to stop rogue AI agents
Why it matters
Agent reliability and safety is moving from theoretical to deployed. A startup built real-time agent governance that judges actions before execution, addressing the most urgent production risk as autonomous systems go live at scale.
Key signals
- Capsule Security released detection system for rogue AI agents
