Sole Source Notice of Intent - Circadence RangeGPT and Range Conductor

The Defense Information Systems Agency (DISA), operating through the Defense Information Technology Contracting Organization (DITCO), has published a Sole Source Notice of Intent regarding a contract award to Circadence Corporation for their RangeGPT cyber range design tool. This special notice, posted on April 29, 2026, announces DISA's intention to award a firm fixed-price sole source contract under Contract Number HC102826P007. The notice cites 10 U.S.C. 3204(a)(1) as the statutory authority for this sole source acquisition, asserting that Circadence is the only responsible source capable of providing all necessary components of the required solution. The contract is classified under NAICS code 541512, with Circadence identified as a large business holding CAGE code 1Y8H0.

The RangeGPT platform is a cloud-based, AI-powered cyber range design tool intended to expedite cyber training and readiness through a graphical user interface-based training and simulation platform. DISA seeks to leverage Circadence's automated accelerated technology and AI solutions to enable responsive end-to-end cyber range creation, broad automatic integration of data sources, improved operational security and risk management, and reduced ongoing personnel requirements across the full cyber range workflow. Interested companies have ten days from the notice publication date—until May 10, 2026—to submit detailed written capability statements demonstrating their ability to provide equivalent services, though no reimbursement for capability information will be provided. No formal solicitation will be posted to SAM.gov due to the sole source nature of the acquisition. Inquiries regarding this opportunity should be directed to either Danni Schwend or Amanda Thole at DISA.
