More Tools Coming Soon
We're building a comprehensive suite of free, open-source cybersecurity tools. Keep an eye on us to see what pops up next. In the meantime, here is a free CAF maturity assessment tool and a Mitre Att&ck Technique selection tool.
Compliance & Auditing
Check out our new Cyber Assessment Framework (CAF) maturity tool. Ideal for UK Government departments and their suppliers. Use it to help inform your as-is and plan out your to-be for CAF maturity.
Threat Modelling
A nice tool to help designers, engineers and SOC analysts to select relevant Mitre Att&ck techniques and to output them either as an Excel (which is good for handing to projects and suppliers) and JSON (if you want to do something with them in code).
