Detection governance, MaGMa maturity, and the Detection System of Record (DSoR) — written for security teams who need to prove detection works, not just measure coverage. Start with what is a Detection System of Record, or explore the latest articles below. Most posts connect threat priorities to declared, validated, and operational outcomes across detection coverage, detection effectiveness, and the health that keeps detections working in production.
The Hidden Variable: Detection Infrastructure Health
April 2026
When validation fails, the rule is not always the problem. Why telemetry pipeline health and detection platform operations are the missing variables — and how teams misread infrastructure failure as bad logic.

Read on secumap.co.ukOperationalising MITRE ATT&CK: Why Use Case Maturity Matters More Than Coverage
January 2026
MITRE ATT&CK is widely used to map detection coverage, but coverage is often mistaken for effectiveness. This article explores why detection maturity matters and where MaGMa fits.
