GrayCheck delivers an independent, evidence-based verdict on your SIEM’s effectiveness: maturity, biggest gaps and NIS2 relevance. Tested on the live system, vendor-neutral — not by self-assessment.
Schematic illustration · SIEM maturity
A SIEM is assumed to “work” — whether it catches real attacks is rarely checked. GrayCheck closes that gap with an evidence-based verdict.
GrayCheck assesses your SIEM across more than 100 criteria in ten domains — from log sources through detection rules to response readiness. Each criterion is weighted and proven on the real system.
The result isn’t a gut feeling but a traceable maturity score with named strengths and gaps — clear for both engineers and management.

GrayCheck maps your detection against known attacker techniques and reveals which areas are covered — and where attackers slip through unnoticed.
So “we have a SIEM” turns into a clear picture of which attacks you are actually protected against today.

Wherever you stand — GrayCheck guides you from a baseline assessment to a supported migration.
Maturity of your current SIEM: score, biggest gaps, clear priorities — the basis for every decision.
Multiple SIEMs or current vs. target — compared objectively, on the same criteria, evidence-based.
A guided move: target architecture, implementation plan and support — so the switch actually works.
The results map to common frameworks — a solid basis for evidence and audits.
