About the company
Trail Of Bits Inc., a small disadvantaged business headquartered in Brooklyn, New York, performs cybersecurity research, software vulnerability analysis, and advanced security tooling development for federal defense and civilian agencies as a prime contractor (89% of recent awards), with limited subcontract engagement. The firm competes predominantly in full-and-open procurements and SBIR/STTR set-asides rather than traditional 8(a) or other socioeconomic set-aside vehicles, though recent work shows mixed set-aside posture — three awards carry Total Small Business designations, two carry no set-aside, and the remainder are Other Transaction Agreements outside FAR scope.
Trail Of Bits' customer concentration is heavily weighted to DARPA, which accounts for 8 awards and $21.6 million (66% of combined potential value) across a portfolio totaling $32.6 million. The next tier includes the Department of Health and Human Services National Institutes of Health (2 awards, $4.9 million for the Defensive Optimization of Network/Software Operations in Healthcare via Automated Remediation Management program), the Department of Justice Antitrust Division (2 awards, $2.6 million for cybersecurity expert services and litigative consulting), and the Department of the Army (3 awards, $1.1 million including an SBIR Phase II contract for $1.999 million). These top five customers account for 84% of recent awards by count and 99% of combined potential value, with DARPA's dominance unchallenged across both metrics. Work is performed in Brooklyn, New York.
Representative capability work spans software security tooling, vulnerability research, and automated remediation. Recent DARPA awards include a $2.677 million definitive contract for the Enhanced SBOM for Optimized Software Sustainment (E-BOSS) program (October 2024, firm fixed price, 20–24 months performance), a $1.416 million Other Transaction Agreement for the Compiler-Enforced Secrecy Seedling program (June 2026, OTA with ultimate completion September 2027), and an SBIR Phase II award of $599,955 for the Polycode research project (November 2023). The National Institutes of Health OTA for the DO NO HARM program carries a $4.939 million ceiling addressing automated remediation management and software security in healthcare. The Department of Justice Antitrust Division awarded two contracts: a $1.275 million expert-services purchase order (January 2026, time and materials, through December 2028) and a $1.275 million litigative-consulting definitive contract (November 2023, labor-hour, through December 2025). The Army SBIR Phase II on Topic A244-P017 carries a $1.999 million ceiling (July 2025, firm fixed price, through January 2027).
Activity has been uneven — two awards in 2021, four in 2023, one in 2024, three in 2025, and two in 2026 — with three awards totaling $8.4 million in combined potential value reaching completion inside the next twenty-four months and facing recompete risk. The firm sits on one parent vehicle, an Indefinite Delivery Contract (FA875021D0001) with one task order. In its limited subcontractor role, Trail Of Bits delivers automated vulnerability discovery and proof-of-concept generation under HRL Laboratories on a DARPA MINDSET (Modeling Intelligent Detection Systems Using Expert Thinking) program addressing medical-device security, and supports contract fulfillment work under Assured Information Security. Award concentration is skewed toward research and development in the physical, engineering, and life sciences (NAICS 541715 or 541714, 13 awards), with secondary work in legal services and custom programming. The portfolio is dominated by DoD R&D and exploratory development (PSC codes R and D categories, 10 awards combined).
