Summary

Hide ▲

Organizations using SIEM are missing most simulated attacks in 2025, with only 1 out of 7 attack simulations detected. The gap matters because failures in log collection, configuration, and performance can leave defenders blind while attackers escalate privileges or exfiltrate data. The trend points to a persistent detection-resilience problem that requires continuous validation, tuning, and log-source coverage.

    Picus Blue Report 2025 reveals a major SIEM detection gap

    Initial Disclosure

    Picus Blue Report 2025 says organizations using SIEM detected only 1 out of 7 simulated attacks across over 160 million real-world attack simulations, indicating a broad detection and response gap in enterprise networks. The findings attribute detection-rule failures to log collection problems, performance issues, configuration issues, unavailable log sources, and delayed test filters, and recommend continuous validation, rule tuning, log-source verification, and Breach and Attack Simulation to close blind spots.
