TL;DR: NIS2 hardens EU cyber resilience by putting identity, access control, incident reporting, and supplier risk at the centre of compliance, according to C1.ai. For IAM teams, the practical issue is that zero trust, least privilege, lifecycle revocation, auditability, and access review automation now form part of regulatory readiness, not just security hygiene.
NHIMG editorial — based on content published by C1.ai: The NIS2 Directive: What to Know and What It Means for Identity Security
By the numbers:
- NIS2 noncompliance can result in fines of up to 10 million EUR or 2% of global turnover.
- NIS2 requires 24-hour early warnings and 72-hour incident notifications for qualifying cybersecurity events.
- Covered entities with fewer than 50 employees and under 10 million EUR in annual turnover are generally excluded.
Questions worth separating out
Q: How should organisations map identity security to NIS2 compliance?
A: Start by linking identity controls to the directive’s risk pillars, especially access control, supply chain security, cyber hygiene and governance evidence.
Q: Why do service accounts and machine identities matter under NIS2?
A: Service accounts and machine identities matter because they often carry the permissions that move data, trigger reports, and feed AI workflows.
Q: What breaks when organisations cannot prove who had access during an incident?
A: Containment slows, reporting becomes uncertain, and investigators lose the ability to reconstruct how an event moved through the environment.
Practitioner guidance
- Map NIS2 in-scope systems to identity owners Build an inventory of critical applications, cloud services, supplier connections, and service accounts, then assign accountable owners for each access path.
- Automate lifecycle revocation for human and non-human identities Tie joiner, mover, leaver events to access removal for employees, contractors, API keys, and service accounts so entitlement changes happen immediately when business status changes.
- Prioritise access reviews for privileged and third-party accounts Start recertification with accounts that can reach regulated data or production systems, then use risk-based sampling to focus reviewer attention on standing privilege, orphaned accounts, and supplier access that has outlived the contract.

NIS2 turns identity governance into a regulatory control surface, not a back-office admin function. The directive's reach across risk management, incident handling, supplier assurance, and reporting means access decisions now have compliance consequences. That shifts identity work from operational convenience to evidentiary discipline, where visibility and revocation quality matter as much as policy wording. Practitioners should treat identity governance as part of resilience engineering, not a separate programme.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
- Our research also shows that only 5.7% of organisations have full visibility into their service accounts, which explains why access review programmes often miss the highest-risk identities.
A question worth separating out:
Q: Which identity controls matter most for NIS2 readiness?
A: Access reviews, lifecycle automation, privileged access governance, and logging matter most because they make least privilege and incident response demonstrable. Organisations should focus on controls that reduce standing access, shorten exposure windows, and produce a reliable audit trail for regulators.
