About the company
Exostar LLC, doing business as Exostar, operates as a for-profit limited liability company based in Herndon, Virginia, delivering managed Microsoft 365 and managed secure desktop cloud services to Department of Defense agencies as a prime contractor (89% of recent awards). Exostar competes in full-and-open procurements with no set-aside designations across its prime footprint.
Exostar's capability portfolio centers on cloud infrastructure and software-as-a-service delivery. The vendor holds a $49 million single-award IDIQ issued by the Defense Acquisition Support Center on May 15, 2026, running through May 14, 2031, for Exostar Managed Microsoft 365 and Exostar Managed Secure Desktop Cloud Services, with place of performance in Herndon, Virginia. Two delivery orders have been issued under this IDIQ: a $2 million firm fixed-price order from PEO Simulation, Training and Instrumentation (award date June 9, 2026, completion December 9, 2026) and a $500 order from the Acquisition Support Center (award date May 19, 2026, completion May 18, 2027). Exostar also holds a position on the General Services Administration Federal Supply Schedule GS35F0219P, which has generated one task order valued at $382 thousand.
Customer concentration is heavily weighted to Army Acquisition Support Center work. The Department of the Army Acquisition Support Center anchors 89% of combined potential value across two awards totaling $49 million, with secondary engagement from the Department of the Navy, the Naval Air Systems Command Naval Air Warfare Center, and the Defense Advanced Research Projects Agency. Activity is sparse in the source data — one award in 2025 and three in 2026 — with two awards (combined potential value $2 million) reaching ultimate completion within the next twenty-four months, creating near-term recompete exposure. Exostar subcontracts to MIT Lincoln Laboratory on a software subscription order supporting the operation of that federally funded research and development center.
