How should organisations use identity governance to meet NIS2 access control expectations in hybrid environments?

Organisations should use identity governance to automate joiner, mover, and leaver access changes, enforce least privilege, and keep role assignments aligned to business need. In hybrid environments, policy driven provisioning and deprovisioning reduce standing access, limit unauthorised exposure, and create a consistent control layer across on premises and cloud systems.

Why This Matters for Security Teams

NIS2 expects access control to be demonstrable, risk based, and consistently enforced across the full identity lifecycle. In hybrid environments, that means organisations need more than a one-time access review. Identity governance becomes the mechanism that ties business approval, role assignment, privileged access, and removal of entitlements into one auditable control layer across on premises systems, cloud platforms, and third-party services.

This is especially important because access sprawl is usually invisible until an incident or audit exposes it. NHI Management Group research shows that 97% of NHIs carry excessive privileges, while only 5.7% of organisations have full visibility into their service accounts in the Ultimate Guide to NHIs. The same structural problem affects human access in hybrid estates when joiner, mover, and leaver processes are fragmented between HR, IAM, and platform teams. NIS2 does not require a single product or vendor model, but it does expect controls that can be proven, repeated, and adapted as the environment changes. Current guidance from the EU NIS2 Directive and NIST Cybersecurity Framework 2.0 both point toward disciplined access management rather than static approvals.

In practice, many security teams discover excessive access only after an audit finding or a lateral movement event has already shown how much standing privilege accumulated unnoticed.

How It Works in Practice

Identity governance should be treated as the operating layer for access control, not just an administrative workflow. In hybrid environments, that means synchronising authoritative sources such as HR, contractor systems, and application owners so that access is granted only when a business need exists and revoked when that need ends. The practical goal is to keep entitlements aligned with role, location, device posture, and privilege tier across both legacy and cloud services.

A workable model usually includes policy driven provisioning, automated deprovisioning, periodic access certification, and privileged elevation through PAM or JIT rather than permanent admin rights. For human users, the governance platform should enforce role based access where the role is stable, and exception handling where it is not. For non-human identities, the same control layer should track service accounts, API keys, workload identities, and secrets so that standing access is minimised. The OWASP Non-Human Identity Top 10 is a useful reminder that long-lived credentials and excessive privilege are recurring failure modes, while the Lifecycle Processes for Managing NHIs section of NHIMG’s guide shows why offboarding and rotation must be built into governance workflows.

• Use a single authoritative workflow for joiner, mover, and leaver events.
• Map business roles to baseline entitlements, then review exceptions separately.
• Require privileged access to expire automatically unless renewed.
• Log approvals, changes, and removals so auditors can trace who changed what and why.
• Include service accounts and secrets in the same governance inventory as human identities.

NIS2-aligned governance also benefits from evidence generation. Access reviews should produce machine readable records, not only screenshots or tickets, because hybrid estates often need proof across multiple control planes. This is where policy as code, SCIM based provisioning, and central identity logs become operationally useful. These controls tend to break down when legacy applications cannot consume central identity signals, because manual exceptions quickly become de facto permanent access.

Common Variations and Edge Cases

Tighter governance often increases operational overhead, requiring organisations to balance stronger access control against application friction and change-management effort. That tradeoff is real in hybrid environments, especially where old systems cannot support modern federation, fine grained entitlements, or automated deprovisioning.

Best practice is evolving for those cases. Some organisations keep a minimal bridge account model for legacy platforms, but current guidance suggests those accounts should be tightly scoped, monitored, and reviewed more frequently than standard user roles. Others adopt compensating controls such as session recording, split approval workflows, or time bound access for high-risk systems. The key is to avoid treating an exception as a permanent design pattern.

Hybrid estates also create boundary problems: cloud identity governance may be mature while on premises directories, mainframe accounts, and vendor-managed platforms remain outside the same policy envelope. NIS2 expectations are still met only if the combined model can show consistent control coverage. For broader context on recurring identity risk patterns, NHIMG’s Top 10 NHI Issues and the Key Challenges and Risks section are useful references, while NIST SP 800-53 Rev 5 Security and Privacy Controls provides the control language many auditors will recognise. The model becomes fragile when organisations rely on manual exceptions for too many legacy systems, because the governance platform then stops reflecting actual access.
