MITRE

A not-for-profit organization that operates federally funded research and development centers to support US government agencies in cybersecurity, defense, aviation, and healthcare. MITRE ATT&CK® Evaluations are widely trusted for their transparency and rigor, offering a detailed look at how endpoint security solutions behave during real-world attack scenarios.
