System Security Plan (SSP) Development and NIST SP 800-171 Compliance Support

The contract requires the development and ongoing maintenance of a System Security Plan (SSP) for systems that process, store, or transmit Controlled Unclassified Information (CUI), ensuring full alignment with the security controls specified in NIST Special Publication 800-171 Revision 1 and the Defense Federal Acquisition Regulation Supplement (DFARS). The scope of work includes implementing, documenting, and sustaining compliance with all 110 security controls outlined in NIST SP 800-171, as well as addressing any additional requirements mandated by DFARS for protecting CUI in nonfederal systems. The contractor must establish a robust security posture through continuous monitoring, risk assessment, and documentation updates to maintain compliance throughout the lifecycle of the systems involved. The contract is structured as a subcontract under the Department of Defense, specifically for the SUBSISTENCE FSE SUPPLY CHAIN, with performance expected to occur at FPO, ZIP 09595. It falls under NAICS code 541611, indicating it is related to management consulting services, though the work is heavily technical and focused on cybersecurity compliance. The solicitation was posted on May 11, 2026, with responses due by May 15, 2026, suggesting a tight turnaround for submission. The successful bidder will be expected to deliver a comprehensive, audit-ready SSP that demonstrates adherence to federal cybersecurity standards and supports the defense supply chain’s requirement for secure handling of sensitive but unclassified information.
