About the company
Def-Logix Inc., a San Antonio, Texas-based SBA 8(a)-certified small disadvantaged business and Hispanic American-owned company, competes as a prime contractor across cybersecurity research and development, software development, and network security services, with 100% of recent awards in prime positions across government-wide acquisition vehicles, SBIR programs, and agency-specific IDIQs. The firm holds SBA 8(a) certification (expiring July 28, 2026) and competes under both Competitive 8(a) and full-and-open postures; its award portfolio concentrates heavily on set-aside and small-business vehicles. Def-Logix operates a subsidiary, Def Secure JV LLC, which is also minority-owned, small disadvantaged, veteran-owned, and Hispanic American-owned.
Def-Logix's capability portfolio centers on cybersecurity architecture, network security situational awareness, automated threat detection, software development, information assurance, and defense systems research and development. Recent representative work includes a $249,978 total-small-business-set-aside definitive contract with the Nuclear Regulatory Commission (awarded August 27, 2026) for cybersecurity research on artificial intelligence and machine learning implementations in operating and advanced reactors, running through August 2027; a $1.04 million SBIR Phase II definitive contract (awarded September 28, 2022) with the Office of the Secretary of Defense for Universal Data Aggregator research; and a $49,999 SBIR Phase I purchase order (awarded October 29, 2021) with the Air Force Research Laboratory for automated network security situational awareness. The firm's GSA Schedule contract (awarded March 24, 2022, expiring March 23, 2027) covers information technology and cybersecurity services across more than thirty labor categories, spanning technical writers and software developers at lower rates ($38.63–$88.74/hr) through senior cybersecurity engineers and architects at higher rates ($105–$192/hr), with roles requiring up to bachelor's education and security clearances for specialized information security positions.
Customer concentration skews heavily toward government-wide acquisition vehicles and defense research agencies. The GSA Federal Acquisition Service dominates by potential value (five awards, $50 billion combined) and is anchored by two OASIS+ IDIQ seats (one Competitive 8(a) multiple-award IDIQ with $999.99 billion ceiling, awarded November 6, 2024, expiring November 5, 2029; one Total Small Business multiple-award IDIQ with no specified ceiling, awarded December 19, 2024, expiring December 18, 2029) and the Federal Supply Schedule contract. NASA ranks second ($40 billion combined potential value) through two SEWP VI GWAC awards (multiple-award with $20 billion ceiling, awarded November 1, 2026, expiring October 31, 2036; one Total Small Business and one Partial Small Business designation). The Air Force Air Education and Training Command and Air Force Materiel Command Research Laboratory together account for eight awards and $1.1 billion in potential value, with three task orders under a prior Air Force Cyber Multiple Award IDIQ. The Missile Defense Agency's Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ (no set-aside, $151 billion ceiling, December 29, 2025–December 28, 2035) carries one delivery order of $500. The Department of Homeland Security Science and Technology Directorate funds five awards ($2.7 million combined).
Activity remains modest and flat — two awards in 2021, two in 2022, two in 2024, two in 2025, and three in 2026 — with only one award (combined potential value $250 thousand) reaching completion inside the next twenty-four months, creating minimal near-term recompete exposure. The combined potential value of $91.11 billion across all awards is overwhelmingly driven by IDIQ ceilings on the OASIS+ and SEWP VI vehicles rather than obligated spend (only $93.6 million obligated across the portfolio to date). NAICS concentration runs toward research and development in physical, engineering, and life sciences (seven awards), software publishing (four awards), and custom computer programming (two awards), with PSC concentration in application development support labor, information technology software, and defense research and development.
