New playbook details defensive gating for autonomous AI agents

Attackers are increasingly using autonomous agents to probe and exploit systems at machine speed, a threat model shift that began in 2026. Traditional defenses are insufficient against this pace, necessitating robust gating mechanisms for agent actions. The proposed solution involves implementing confidence-and-risk gates for every tool call, enforcing least privilege per task, and setting rate and blast-radius caps to limit potential damage when a gate fails. This framework aims to automate safe actions while reserving human intervention for high-impact or irreversible operations, ensuring auditable decision-making. AI
