Detection Engineering that Proves Coverage Still Works
Rules are only valuable when they still fire at the right time. Content updates, schema changes, parser drift, new data sources and tuning suppressions silently break coverage. VanatorX gives teams a production‑aware engineering loop spanning hypothesis → rule authoring → emulated validation → scheduled canary re‑run → regression diff.
We focus on the platforms you already operate—Microsoft Sentinel, Splunk, Elastic, SentinelOne, CrowdStrike, generic Sysmon / ETW pipelines. Author once, translate, test everywhere and measure impact with objective metrics.
Multi‑Platform Focus
Unified Authoring
Field catalogs & context assistance for each platform. Author in neutral syntax (Sigma‑like) then export native queries with source‑aware adjustments.
Emulated Validation
Replay real adversary chains + scheduled canaries. Measure precision, recall, latency & regression vs prior baselines.
Coverage Intelligence
Technique & sub‑technique mapping, data component presence, overlap & gap scoring across telemetry sources.
Noise Compression & Tuning
Benign frequency tracking, variant aggregation, suppression candidate ranking and before/after noise impact.
Bypass & Drift Surfacing
Rule fragility tests: field removal, value mutation, timing jitter, sequence reordering. Alert delta diff exports.
Change Impact History
Every change (parser update, whitelist, new source) automatically re‑evaluates canaries to show what broke immediately.
Continuous Effectiveness Metrics
- Rule health: last success, volume, distinct entities, decay curve
- Coverage delta by tactic / technique per platform
- Regression & bypass score (what silently stopped firing)
- Noise compression & false positive budget tracking
- Mean time to improve (MTTI) after regression detection
Reporting & Stakeholder Views
- Executive dashboard: assurance score, risked coverage, trending
- Engineer diffusion: failing steps & suggested analytic patterns
- Compliance pack: immutable evidence bundle + hash
- Board / leadership snapshot: dwell time & regression status
