GrayCheck assesses your security tools such as SIEM, XDR, vulnerability scanners and more — a structured questionnaire, workshops with your team and insight into the running system instead of mere self-assessment. You get a vendor-neutral maturity score, your biggest gaps and a clear picture of what actually protects you.
Independent — we don’t sell SIEMs. Built on real assessments and 15+ years of security practice.
Sample illustration
Whether you still need to decide which security tools make sense, want an independent assessment of your existing stack, or want to keep your attack surface under continuous watch — Graydaxe covers all three steps. Vendor-neutral, evidence-based and with clear, actionable recommendations for your team.
Before you invest: which solutions make sense and are cost-effective — plus target architecture, migration and compliance (NIS2, ISO 27001, Zero Trust). Built on 15+ years of practice.
An independent verdict on the effectiveness of your existing tools — SIEM, XDR, vulnerability scanners and more: maturity, biggest gaps, NIS2 relevance. (GrayCheck)
Continuous visibility into your externally exposed assets, vulnerabilities and leaked credentials — operated by us as a managed service. (GrayScope)
No SIEM yet, or unsure which tools you actually need? In many cases, we support companies one step before assessing existing security tools or SIEM — namely with the question of which solutions make sense and are cost-effective in the first place.
Graydaxe is a cybersecurity company from Berlin — we combine hands-on security services with our own AI-assisted tools. GrayCheck, our new, independent SIEM assessment, adds to this portfolio — another building block following the principle See → Assess → Improve.
Security has more than one perspective. We examine all three — vendor-independent — and deliver concrete tools and services for each.
What attackers can see and exploit from outside: exposed assets, vulnerabilities, leaked credentials — detected and ranked by real risk. Available as a guided service.

Whether your detection truly works — assessed on the running system, not just by self-assessment. Today for SIEMs (GrayCheck), gradually also for other security tools and SOC processes.

How to build and run it right: vendor-neutral architecture, risk assessments, guided implementation.

A SIEM rarely fails on feature set. It fails on gaps in data, architecture, processes and operations — and those stay invisible until it matters.
Looks like full coverage — except for the blind spot where the attack sits.
That’s how false confidence forms: the SIEM is running, the dashboards are green — but when it counts, it doesn’t detect what matters. GrayCheck makes exactly these gaps visible — before an attacker finds them.
100+ criteria across 10 domains, assessed on the running system instead of just surveyed. Three modes — from the maturity of a single SIEM to a guided migration. You decide how deep you go.
The maturity check for a single SIEM.

A SIEM that “can” do every feature still often fails to detect what counts. GrayCheck doesn’t assess feature scope, but actual effectiveness — structured, traceable and independent.
Not just self-assessment: a questionnaire, workshops with your team and insight into your running SIEM together form a reliable picture.
We don’t sell SIEMs. We assess the impact in your environment — independent of the product in use.
From log sources through detection to resilience — every relevant area is examined systematically and weighted by risk.
Your results map directly to the regulatory requirements — usable for audits and evidence obligations.
The assessment comes from people with security practice. Our AI engine GrayD supports them — and checks the results for inconsistencies.
The outcome isn’t a data graveyard, but an understandable maturity score, your biggest gaps and concrete next steps.
The same logic — effectiveness instead of a feature list — transfers to other security tools and SOC processes. The SIEM comes first, because that’s where most gaps go unnoticed.
We deliver each of our services as a guided engagement today and move them step by step into the Graydaxe platform. Our AI engine GrayD runs through all of it — supporting the analysis and checking results for inconsistencies.
An independent verdict on your SIEM’s effectiveness: maturity, biggest gaps, NIS2 relevance.
Continuous visibility into your externally exposed assets, vulnerabilities and leaked credentials — operated by us. No in-house security team required.
A one-off risk assessment as a standalone report — aligned with ISO 27001, NIS2 and other standards.
Zero-trust architecture, threat modeling, risk assessment, compliance support and workforce architecture — grounded in 15+ years of practice. Not a slide deck, but impact.
Whether you have your own SOC, a small team or none at all — you use each service yourself, partly guided or fully operated by us.
Security evidence rarely fails on willingness, but on provability. GrayCheck delivers your SIEM’s detection and logging maturity in a structured, traceable form — directly usable for audits and evidence obligations.
| Standard | What a GrayCheck assessment delivers |
|---|---|
| NIS2 EU directive | Traceable statements on detection coverage, logging and incident documentation — as a basis for reporting obligations. |
| ISO 27001 | A solid classification of logging, monitoring and continual improvement. |
| BSI IT-Grundschutz / SOC 2 | A structured assessment of detection, resilience and operations as an audit basis. |
The assessment doesn’t replace a certificate — it provides the solid basis that audits and evidence build on. Beyond the SIEM, our other services (Attack-Surface Monitoring, Security Check, architecture) feed into the same standards.
As a cybersecurity services provider and tool maker from Berlin, we combine guided services with our own AI-assisted modules. GrayCheck is our newest solution — another building block in a growing portfolio following the principle See → Assess → Improve.

Articles on SIEM effectiveness, detection coverage and NIS2 — from the practice of real assessments, not from product marketing.
GrayCheck is a vendor-neutral SIEM assessment by Graydaxe: 100+ criteria in 10 domains result in a clear maturity score, your biggest gaps and concrete next steps — evidenced on the running system, not by self-assessment.
The assessment combines a structured questionnaire, workshops with your team and insight into your running SIEM. The result is a weighted maturity report with a strengths/weaknesses overview and prioritised recommendations.
Yes. We do not sell a SIEM and are not tied to any vendor. What is assessed is the actual effectiveness in your environment — regardless of which system you use.
NIS2 requires verifiable detection, logging and reporting capabilities. GrayCheck delivers structured, traceable statements on exactly that — directly usable as a basis for audits and evidence obligations, also for ISO 27001 and BSI IT-Grundschutz.
No. GrayCheck works with your own SOC, a small team or none at all. Where gaps become visible, we can support you with managed services such as attack surface monitoring or consulting & architecture.
The effort depends on the size and complexity of your SIEM environment. You get a first, free impression of your maturity level via a demo — followed by a clear quote.
