Our approach
Why we publish honest comparisons
Open Risk Register is a free, open-source tool. We do not earn revenue from tool sales or referrals. Our comparisons aim to be factually accurate, including cases where another tool is a better fit. If you spot an error, check the source code and open an issue.
The right tool depends on your organisation: its size, existing IT infrastructure, team skills, budget, and the specific NIS2 obligation you are trying to meet. No single tool is the right choice for everyone.
Disclaimer: Tool features change frequently. Descriptions reflect publicly available information at time of writing and may be outdated. Always verify current capabilities directly with each vendor. Nothing on this page constitutes legal or compliance advice.
