NIS2 Tool: Buyer's Guide for Compliance Software
What NIS2 tools you actually need, what they cost, what to look for, and which features are mandatory under the directive.
A NIS2 tool is software that helps companies implement the EU NIS2 Directive (2022/2555) and its national transposition. It must support the 10 cybersecurity measures from Article 21 NIS2 plus incident reporting and authority registration.
- NIS2 requires durable audit evidence — Word documents are not enough.
- Authorities check response times (24h / 72h / 1 month) — hard to demonstrate manually.
- Personal management liability: you need proof measures were implemented.
- The 10 measures from Article 21 span multiple departments — coordinated tools save time.

What does a NIS2 tool cost?
Commercial GRC tools (Vanta, Drata, OneTrust) run €10,000–€60,000 per year for a mid-sized company. nisd2.eu is free.
Do I need a tool, or is Excel enough?
Excel is not enough. Authorities require a tamper-evident audit trail. After an incident, you must prove who changed what when.
Is one tool enough, or do I need several?
A GRC tool covers documentation and proof. For SIEM, patch management, MFA, backups you still need separate technical tools.
Can a free platform be NIS2-compliant?
Yes. NIS2 doesn't mandate a specific vendor. What matters is whether the requirements are met and documented.
