Content library

A content library is a vendor- or community-maintained set of ready-made detections. Buyers use one to start from coverage instead of a blank page. Size matters less than freshness, fit to your data and whether you can read and edit what you get.

What Content library means here

Counts are claims. Check whether a number is dated and what it counts: rules, analytic stories or detections.

A library also has to be run: each rule needs the right data and tuning on your estate.

Example of Content library in Sekoia documentation

Sekoia's Verified Rules page says there are more than 1000 rules, a count with no date, and says they are continuously updated. docs.sekoia.com read 2026-11-03
