Sentyron Software Maintenance and Support Renewal

NASA's Shared Services Center seeks renewal of maintenance and support services for Sentyron DataDiode software at NASA Ames Research Center, with quotes due May 18, 2026 at 3:00 p.m. Central Time. The procurement is set aside for total small business and is a brand name requirement for Sentyron B.V., the original equipment manufacturer of the proprietary data diode systems currently deployed.

Place of performance is NASA Ames Research Center, Moffett Field, California 94035-1000, under the direction of Thomas Volden. The requirement covers four units identified by serial numbers 6191310375, 6191310400, 6191310401, and 6191310402. Period of performance runs from June 1, 2026 through May 31, 2028, with core-level maintenance coverage specified. The NAICS code is 541519, Other Computer Related Services; PSC is DG01, IT and Telecom—Network Support Services (Labor). Delivery is FOB Destination.

The Sentyron systems are integrated into the isolated wind tunnel network architecture and enforce one-way data transfer between security zones. The brand name justification established that alternative data diode solutions are not directly compatible with current hardware and would require full system replacement, resulting in substantial cost increases and schedule delays for security accreditation.

Award will be made to the responsible offeror whose conforming offer represents the lowest price technically acceptable option. Offerors must be registered in SAM.gov. All contractual and technical questions are due in writing by May 15, 2026 at 3:00 p.m. Central Time; telephone questions will not be accepted. Submit questions to Kacey Hickman at Kacey.l.hickman@nasa.gov. Quotes must remain valid for 30 days and include two points of contact with names, phone numbers, and email addresses.
