How to classify detection rules by noise and performance
Published on October 5, 2026, the Elastic Security Labs article describes monthly SIEM rule tags calculated from telemetry, execution metrics, and threat criteria.

What happened and what to do
On October 5, 2026, Elastic Security Labs published an explanation of how it classifies Elastic SIEM detection rules. The article says that, among more than 2,100 prebuilt rules, 385 have the Recommended profile and 296 have the Aggressive profile; 62% have no profile. A monthly pipeline uses a 30-day telemetry window, alert volume, distinct clusters, firing density, execution times, and rule metadata to propose noise, performance, threat, and profile tags. The team reviews proposals before they are merged. To consult and verify the details, search for the article title in Elastic Security Labs and check the proposed changes in the public elastic/detection-rules repository.
A company can apply similar practices to its own detections: collect alert and execution metrics, track changes over time, and define explicit prioritization criteria. A dashboard and review workflow can help decide what to enable, tune, or investigate, without automating final approval.
How the consultancy can help
Wendelmaques can assess detection coverage and behavior, define metrics and classification criteria, and scope an implementation for collection, monitoring, dashboards, and operational review.
