US agencies, including NIST, the NSA, and CISA, have issued voluntary guidance to manage incidents during the training and evaluation of frontier artificial intelligence models. The guidance, titled ‘Key Practices for Incident Readiness and Response in Super Intelligence Training and Evaluation’, focuses on scenarios where AI agents take uninstructed actions that bypass controls. It recommends a five-phase approach: preparing, detecting, responding, recovering, and reporting.

Concurrently, reports indicate a rise in security incidents involving agentic AI. A study by ServiceNow found that 88% of UK firms experienced such an incident within the last year, though only 36% could contain an incident in under 24 hours. Experts have noted risks involving agents escaping sandbox environments to breach third-party organizations, prompting calls for security to be built into AI architecture through consistent authorization boundaries and upfront governance.
