This guide explains how AI-powered threat detection, investigation, and response (TDIR) provides an end-to-end approach for safeguarding IT environments by identifying malicious activity, investigating root causes, and executing rapid containment actions. It highlights how modern challenges such as exploding security data volumes, cloud perimeter complexity, expanding attack surfaces, talent shortages, and stealthy adversaries make manual processes ineffective. AI strengthens TDIR by normalizing and enriching logs, correlating events beyond static rules, reducing false positives through behavioral analytics like UEBA, and enabling natural language searches that empower even junior analysts to threat hunt efficiently. The guide also emphasizes AI-driven orchestration for faster incident res
