The challenge
With the NIS2 directive, many companies faced a new reality: stricter cybersecurity requirements, incident reporting obligations, and personal liability for executives. Our client – a company in the critical infrastructure sector – had organically grown security structures but lacked unified documentation and a clear overview of the compliance status regarding the new demands. Time was of the essence: the implementation deadline was approaching, and there was a shortage of both internal resources and a clear roadmap. The goal: Achieve NIS2 compliance – technically, organizationally, and documented – without jeopardizing ongoing operations.
Inside the rollout
We started with a comprehensive gap analysis: Where does the company stand today, and what are the gaps to the NIS2 requirements? The result was a prioritized action plan with quick wins and strategic initiatives. On the technical side, we implemented Microsoft Defender XDR as a central security platform and integrated all relevant signals into Microsoft Sentinel. Entra ID Governance ensures traceable access controls and regular access reviews. Conditional Access Policies guarantee that only compliant devices and verified identities gain access.
In parallel, we built up the required documentation: policies, processes, incident response plans, and evidence for the auditor. The result: Timely NIS2 compliance, a significantly improved security posture, and a company that is prepared for future audits. On-time NIS2 compliance with full documentation, augmented security posture, and audit readiness for upcoming evaluations.
„NIS2 is not a documentation project — compliance emerges when technology, processes, and evidence add up to the same picture.“

Learnings
- A gap analysis with a prioritized action plan beats blind activity: quick wins create momentum, strategic initiatives provide the substance.
- Consolidation helps compliance: Defender XDR and Sentinel as a central platform simplify evidence management and incident reporting processes.
- Access control must be traceable: Entra ID Governance with regular access reviews delivers exactly the evidence auditors expect.
- Build documentation in parallel with the technology — catching up on policies and incident response plans afterwards costs time and consistency.
What's next
With compliance achieved on schedule, the real ongoing task begins: NIS2 demands lived processes, not a one-off certification. The documentation built up, the incident response plans, and the regular access reviews are designed to be maintained continuously in operations. Future audits will thus encounter a company that does not have to reconstruct its evidence but keeps it continuously up to date.
