The Insider Risk Incident Response Playbook

A Practical Framework for Detecting, Investigating, and Containing Insider Risk

Insider risk is not an anomaly. It is a structural feature of how modern organizations operate, since employees create, share, and act on sensitive data every day. This playbook gives security teams a structured approach to detect insider threats, classify the data involved, and contain incidents before damage is done, including the new risks introduced by shadow AI and agentic workflows.

‍

Key Takeaways:

• Insider incidents trace back to three root causes, negligent behavior, malicious insiders, and departing employees, and each requires a different response from security teams
  
• The thirty days before and after a resignation notice concentrate the highest risk in the employee lifecycle, a window most offboarding processes fail to monitor
  
• Data lineage closes the gap legacy DLP and IRM tools cannot, tracking sensitive data through AI tools and agentic workflows and reducing false positives by more than 90%
