Picus' Blue Report 2024 (DRV data) finds that many SIEM detection rules are ineffective due to issues such as improper log source consolidation (23%), unavailable/broken log sources, performance-related queries, and empty reference sets; the report recommends continuous detection rule validation and use of Picus DRV to identify, remediate, and optimize rules so SOCs can maintain reliable threat detection and response.
