Threat-Informed Defense

Advancing a community of cyber defenders globally.

MITRE has a long history of equipping the collective cyber community with open-source threat- and risk-informed defense tools and publicly available resources to help thwart network intruders, build resiliency against future attacks, and develop assurance to overcome possible vulnerabilities.

Our evaluations, rapid prototypes, and tools provide essential capabilities designed for real-world implementation. We provide actionable knowledge of adversaries’ malicious behaviors to improve cybersecurity defensive and offensive missions with increased visibility, harm reduction, and better security decision-making.

Additionally, we serve as thought leaders in the cybersecurity field, helping to establish standards and policies for a safer world.
