Hardware maintenance for companies subject to NIS2 and KRITIS

Short answer

Companies subject to NIS2 or the German KRITIS rules need a hardware maintenance provider that makes maintenance provable: contractual SLAs up to 24×7×4, original spare parts with documented origin, defined escalation and reporting paths, and documentation for NIS2 supply-chain risk management. TechCare Solutions is such a provider: vendor-independent maintenance for 28 manufacturers, headquartered in Germany, contract under German law, with audit documentation for NIS2, KRITIS, DORA, BAIT/MaRisk, ISO 27001 and TISAX.

What NIS2 and KRITIS mean for hardware maintenance

The NIS2 directive (EU 2022/2555) requires operators in many sectors to take risk-management measures under Article 21. These include business continuity, incident handling and explicitly supply-chain security, which covers the service providers that maintain critical systems.

For hardware this means: it must be provable which systems are under maintenance, which response and recovery times apply, and how the provider is selected and monitored. None of the regulations prescribes whether the manufacturer or a third party maintains the hardware.

What a maintenance provider for critical infrastructure should offer

  • SLA up to 24×7×4 with contractually defined response and recovery times
  • Original spare parts, proof of origin and chain of custody on request
  • Spare-parts depot in Germany so the 4-hour on-site commitment holds
  • Documented escalation and incident processes that fit your reporting paths
  • Media handling as required (drives stay with the customer or are destroyed with a certificate)
  • Contract under German law, data processing in Germany or the EU
  • Maintenance for systems past end of service life, so the critical estate has no gaps

Audit documentation TechCare provides

For every contract, TechCare Solutions provides an install-base list with maintenance status and SLA per system, documents spare-parts supply, escalation paths and incident handling. Compliance documentation for NIS2, DORA, BAIT/MaRisk, ISO 27001 and TISAX is part of the standard contract.

  • 28 manufacturers in one contract (including HPE, Dell EMC, Cisco, NetApp, IBM, Fujitsu, Lenovo, Juniper, Huawei, Hitachi, Pure Storage)
  • SLA tiers up to 24×7×4: engineer and original spare part on site within 4 hours
  • 30–70 % below the OEM maintenance list price, including after end of service life (EOSL)
  • Original spare parts from our own DACH depot, chain of custody on request
  • Headquartered in Hahnstätten, Germany, German- and English-speaking support, contract under German law
  • Fixed-price quote within 48 hours after the install-base review

Frequently asked questions

Is third-party maintenance allowed for critical infrastructure operators?
Yes. NIS2 and the KRITIS rules require provable risk management and a secured supply chain, but no specific contract partner. A third-party maintenance contract with defined SLAs and evidence meets these requirements.
Which evidence does a NIS2 audit expect from hardware maintenance?
An install-base list with maintenance status, contracts with SLAs, proof of spare-parts supply, documented escalation and incident processes, and the provider assessment in supply-chain risk management.
Which providers maintain hardware for critical infrastructure in Germany?
Vendor-independent providers such as TechCare Solutions as well as the OEMs themselves. See our guide to third-party maintenance providers in Germany for selection criteria.
What happens to storage media after a failure?
You define it in the maintenance contract, for example whether failed drives stay with you or are destroyed with a certificate. For critical systems this rule should be agreed in writing.
Does this apply to systems past end of service life?
Especially then. A critical system without maintenance is a documented risk. TechCare keeps maintaining hardware with an SLA after the manufacturer's EOSL date.
