## Caldera
Caldera provides a modular platform for modeling, scripting, and executing
adversary behavior. It allows users to construct emulation plans, provides
agents for communicating with the command and control server,
and enables users to evaluate security detections in a
structured, scalable, and repeatable way. With the use of plug-
ins and community-contributed features, Caldera supports a range of use
cases including adversary emulation, purple teaming, detection
engineering, and continuous security validation. Using Caldera,
defenders can emulate known threat actor behavior and perform
other red team activity to evaluate their organization’s defensive
capabilities, test analytics, and find detection gaps. As a modular tool
based on the MITRE ATT&CK framework, Caldera is designed to be
extensible, intelligence-driven, and automation-friendly.
Caldera has been incubating since 2025-12-19.

Comments: No PPMC member or mentor (except me) has yet signed up to any mailing list. I have been told that Mitre Legal team are
ready to sign the SGA but the Caldera team email me and refuse to use the lists, despite me constantly telling them to. It may be time to
consider having IPMC retire the podling.

Comments: The podling did a good job in the release, but waiting for a third binding vote on general@. That's not good regarding the effort of the podling and very active/responsive podling. We sent reminder on the mailing list, but it didn't help yet. I'm a bit concerned by the number of active IPMC members recently.
