On point: NIS2 makes written documentation of patch management and incident response at suppliers an auditable compliance requirement.
The NIS2 Directive obliges suppliers to document their patch management and incident response processes in writing. This requirement becomes an auditable obligation in the supply chain for those responsible for compliance.
The NIS2 Directive (Network and Information Security Directive) establishes concrete requirements for the documentation of security processes at suppliers. This particularly affects patch management procedures and processes for handling security incidents, which must be documented in writing and verifiably recorded.
For those responsible for compliance, this means that the previous practice of oral assurances or vague commitments is no longer sufficient. Suppliers must document their processes, and buyers must review these documents as part of their due diligence obligation and be able to archive them. This applies to both technical implementation (patch deployment plans, time horizons) and organizational escalation (Who reports incidents? To whom? Within what timeframes?).
In practice, this means: compliance teams must expand their supplier audits accordingly, establish new evidence templates, and integrate received documentation into their governance processes. The requirement applies regardless of whether the supplier itself is NIS2-regulated or is only an indirect party in the supply chain.
