Threat Modeling Tools

MS Threat modeling tool, Cairis, Iriusrisk, Kenna, OWASP pytm, OWASP threat dragon, threagile are some of the most known threat modeling tools I know.

Personally I like OWASP Threat Dragon for being supported on most common platforms, and because of its flexibility in designing and registering threats. MS Threat modeling tool provides a lot of out-of-the-box threat scenarios with details based on the model designed.
