The cybersecurity sector is experiencing significant investment in ‘agentic security’ to manage the risks associated with autonomous AI agents.

Initial developments included Lisbon-based Humanos securing $3.2 million in seed funding to develop real-time risk scoring for agent behavior, and Israeli startup Rig Security launching with $12 million to distinguish between human and agent activity via an ‘Identity Correlation Engine’.

This trend of investment escalated with major funding rounds for specialized firms. Palo Alto-based Armadin raised $255.5 million in Series B funding to use AI agents for simulating network attacks, while Florida-based Reco secured $55 million to provide visibility and control over AI agents accessing business applications and data.
