Why Defensive Coverage Doesn’t Equal Detection Effectiveness

The report argues that security teams often mistake coverage (tool presence and ATT&CK mapping) for true defensive effectiveness, and urges continuous validation of detections through adversary simulation and testing. It emphasizes that detection engineering, tuning, and validation — not just adding tools or mapping techniques — determine whether defenses will detect and stop real attacks, and it positions Tidal Cyber’s Threat-Led Defense as a solution.
