Compliance is a floor, not a ceiling
The best compliance programmes do not just satisfy auditors — they give organisations a clear, honest picture of their actual security posture. A good audit is not a box-ticking exercise. It is a structured, evidence-based process that surfaces real gaps, prioritises remediation, and produces documentation that holds up under scrutiny.
Nomios brings independent, experienced auditors and security consultants to every engagement — combining deep technical knowledge with regulatory expertise to deliver audits that are rigorous, actionable, and built for the European regulatory environment your organisation operates in.
Five specialist disciplines
Each addressing a different compliance driver — from regulatory mandates to technical assurance to supply chain risk.
- A structured gap assessment against NIS2 Article 21 obligations and DORA ICT risk management requirements — identifying where you stand, what needs to change, and how to demonstrate compliance to your regulator.
- Internal audit, gap assessment, and certification readiness support across the ISO 27001 Annex A control set — from scoping your ISMS through to supporting your certification audit and annual reviews.
- Hands-on technical assessments of your security controls — architecture reviews, configuration audits, penetration testing, red team exercises, and vulnerability assessments — providing evidence-based findings your team can act on.
- Assessing the security posture of critical suppliers and partners — through questionnaire-based assessments, evidence reviews, and on-site audits — giving you defensible evidence that your supply chain is managing risk appropriately.

We audit against the frameworks that matter
Our auditors hold deep expertise across the European regulatory landscape — giving you assessments that satisfy supervisory scrutiny, not just internal comfort.
NIS2
- Article 21 control mapping, governance structure review, incident response capability assessment, and supervisory reporting support for operators of essential and important entities.
DORA
- ICT risk management framework assessment, operational resilience testing readiness, and third-party ICT risk programme review for financial entities across Europe.
ISO 27001
- Internal audit, Annex A control assessment, ISMS gap analysis, and certification readiness — supporting first-time certification and ongoing surveillance audit cycles.
GDPR
- Data protection compliance audit, DPIA review, records of processing assessment, and breach response procedure evaluation — aligned to supervisory authority expectations.
IEC 62443
- OT and industrial control system security audit against the international standard — covering zone and conduit design, security levels, and maturity assessment for operational technology environments.
Custom frameworks
- Sector-specific requirements, internal policy frameworks, and customer contractual obligations — our auditors work to the standard that is most relevant to your organisation and stakeholders.
A rigorous, consistent audit process
01 — SCOPE: Define scope & objectives
We agree what is in scope, which framework applies, and what the audit needs to demonstrate — to auditors, regulators, or your board.
02 — ASSESS: Evidence gathering & testing
Document review, interviews, configuration analysis, and technical testing — depending on audit type. We gather evidence, not just assurances.
03 — REPORT: Findings & gap analysis
A structured report with risk-rated findings, control gaps, and context — written for both technical teams and the board or auditor who will review it.
04 — REMEDIATE: Roadmap & follow-up
A prioritised remediation roadmap — and, where needed, support to implement the changes that bring you into compliance.
What sets our audit practice apart
Technical depth, not just checklists
- Our auditors include hands-on security engineers and penetration testers — giving us the technical credibility to go beyond document review and test whether controls actually work.
Independent and genuinely objective
- We have no interest in finding more work to sell. Our audit findings reflect what we actually discover — giving you an honest picture you can trust and act on.
European regulatory expertise
- NIS2, DORA, ISO 27001, GDPR — we understand the regulatory landscape European organisations operate in, and we write audit reports that satisfy supervisory expectations.
Audit to implementation in one partner
- When an audit identifies remediation work, our Professional Services team can deliver it — no gap between finding the problem and fixing it.
