Cyber Agents for Security Testing and Learning Environments (CASTLE)

The Defense Advanced Research Projects Agency seeks proposals through December 22, 2022 to develop an artificial intelligence toolkit under the Cyber Agents for Security Testing and Learning Environments program. The program aims to instantiate realistic network environments and train cyber agents to enable resilient network operations against advanced persistent threats. Proposals will be evaluated based on scientific and technical merit, contribution to the DARPA mission, and cost and schedule realism, with multiple awards anticipated across three technical areas over a four-year period consisting of three phases.

There is no set-aside designation for this opportunity. The main NAICS code is 541715 and PSC code is D308. The program budget is approximately $#.# million for the development of an open-source AI toolkit to simulate and defend network environments and workflows using reinforcement learning experimentation on live networks to model over one hundred attack paths and defensive actions per year.
