The Problem

The Detection Debt Cycle

Generic rules, coverage gaps, and slow deployment lock every SOC into a loop that never breaks on its own.

Generic rules flood your SOC with noise

Analysts spend hours tuning suppressions and chasing false positives instead of investigating real threats.

Coverage gaps go unnoticed for months

Blind spots across credential access, lateral movement, and defense evasion sit open.

New rules take weeks to deploy

Write, test, validate, review, deploy. By the time it's live, the threat has moved.

MITRE ATT&CK Mapping

Know exactly what you can and cannot detect.

Every rule is automatically mapped to ATT&CK tactics and techniques, with a live coverage heatmap showing exactly where your detection gaps are. Gap prioritization is weighted by your environment's threat profile, so you fix the right blind spots first.

AI-Assisted Tuning

Reduce false positives without sacrificing coverage.

Automatically reduce false positives by learning your environment's baseline. Decanos AEP identifies which alerts are noise in your specific context and suppresses them intelligently, preserving coverage for genuine threats while eliminating the alerts that desensitize your team.

Rule Lifecycle Management

Every rule reviewed, versioned, and production-safe.

Version control, a testing sandbox, staged rollout, and a full audit trail for every rule. Your detection library is always compliant, reviewed, and production-safe. No detection engineer deploys to production without a documented approval chain.

Version control, testing sandbox, staged rollout, and full audit trail for every rule.
