About this award

Written by GovTribe AI ·

The Defense Advanced Research Projects Agency awarded a $5.557 million definitive contract to Vanderbilt University for the Cyber Agents for Security Testing and Learning Environments (CASTLE) program on July 1, 2024, with completion targeted for August 13, 2027. The contract carries cost-no-fee pricing and no set-aside designation.

CASTLE aims to build a state-of-the-art reinforcement learning environment for network operations that trains both blue team agents to learn defensive actions maintaining environment workflows and red team agents to enumerate attack paths using environment vulnerability exposures. Place of performance is Nashville, Tennessee.

The originating pre-solicitation (posted October 21, 2022) sought proposals to develop an artificial intelligence toolkit enabling realistic network environments and resilient network operations against advanced persistent threats. The DARPA program structure anticipated multiple awards across three technical areas over four years in three phases, with proposals evaluated on scientific and technical merit, contribution to DARPA mission, and cost and schedule realism. NAICS 541715; PSC D308.

Vanderbilt's Sponsored Programs Administration Division administers the award. Named subcontractors include the University of Virginia (with subcontract awards dating from July 2024 through January 2026) and Leidos Solutions Operating Segment (with subcontract awards from August 2024 through January 2026), both supporting development of the RL environment and network simulation capability.
