NIS2 and KSC 2026: data center infrastructure checklist for companies

NIS2 and KSC readiness starts with knowing where systems run, who has access, how backup works, who reacts to incidents and whether the infrastructure provider can document its processes.

Short answer

NIS2 and KSC readiness starts with knowing where systems run, who has access, how backup works, who reacts to incidents and whether the infrastructure provider can document its processes.

Service inventory

Start with systems, owners, domains, IP addresses, technical accounts, dependencies, providers and integration points.

Access and responsibility

NIS2 requires practical access control: accounts, roles, VPN/SSH/RDP, administrator rights and audit trail.

Backup, DR and monitoring

Backup alone is not enough. RPO/RTO, restore testing, backup monitoring, emergency procedures and escalation are required.

Data center provider

Ask about certifications, SLA, processes, support, physical security, network, backup, administration and incident documentation.

Practical checklist

  1. Create a system list and mark critical, important and auxiliary services.
  2. Document administrator access, technical accounts, VPN, SSH, RDP and permission removal process.
  3. Check backup: retention, encryption, monitoring, restore testing and RPO/RTO.
  4. Define incident procedure: contact, escalation, logs, decisions and communication.
  5. Map requirements to services: colocation, VPS, Cloud Pro, dedicated servers, administration and monitoring.

Frequently asked questions

Does a data center alone ensure NIS2 compliance?

No. It is part of the supply chain and can help with processes, infrastructure, monitoring and documentation, but compliance also covers the customer's organisation.

What should be checked in an infrastructure provider?

SLA, certifications, physical access, procedures, backup, monitoring, incident handling, network and responsibility split.

Does NIS2 apply only to large companies?

Not only. Check key or important entity status, sector duties and supply-chain role.
