SIEMs now process an average of 259 log types and nearly 24,000 unique log sources, providing more than enough telemetry to detect over 90% of MITRE ATT&CK techniques (an increase of three percent from 2024) – but manual, error-prone detection engineering practices continue to limit actual coverage.

79% of MITRE ATT&CK Techniques used by adversaries are missed by enterprise SIEMs.
