Sixgen Inc.

Sixgen Inc., headquartered in Annapolis, Maryland, is a small-business prime contractor delivering cybersecurity assessment, consulting, penetration testing, and data-breach response services to federal agencies through full-and-open competition and small-business set-aside vehicles. The company operates across three subsidiaries—Secure Enterprise Engineering LLC, Kyrus Tech LLC, and Boldend Inc.—and derives most of its recent dollar value from a single large-ceiling delivery order rather than a broad customer base.

Sixgen's customer concentration is severely skewed. The Department of the Treasury Bureau of the Fiscal Service accounts for 97% of combined potential value ($58.2 million) through a single June 2026 delivery order extending to June 2031 for cyber security assessment, consulting, and data breach response services under the GSA Multiple Award Schedule. The remaining customer base is fragmented: the Department of the Navy Naval Sea Systems Command (3 awards, $1.2 million), GSA Federal Acquisition Service (3 awards, $700 thousand), the Department of the Army Space and Missile Defense Command (2 awards), the Department of the Air Force Defense Finance and Accounting Services (2 awards), and the DOD Missile Defense Agency (2 awards, $500 ceiling). Nine distinct federal agencies appear across the sixteen recent awards in the source.

Sixgen holds positions on multiple government-wide vehicles. The company is a multiple-award awardee on the OASIS+ Unrestricted IDIQ (no set-aside) and the OASIS+ Total Small Business Set-Aside IDIQ, both awarded December 2024 and running through December 2029, positioning it to compete for task orders across seven functional domains (management and advisory, technical and engineering, research and development, intelligence services, environmental services, facilities, and logistics). The company also received a $151 billion multiple-award IDIQ from the Missile Defense Agency on December 29, 2025, under the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program, covering multi-domain defense systems work including systems engineering, cybersecurity, prototyping, and test and evaluation across classified and unclassified programs, with performance expected at locations including Huntsville, Alabama and supporting both MDA and broader Department of Defense entities through 2035.

Sixgen's capability portfolio centers on cybersecurity operations, penetration testing, vulnerability assessment, and workforce development. Recent prime work includes the $58.2 million Treasury cybersecurity order, a June 2025 $16.8 thousand delivery order from the Navy for "Hack the Box" workforce development training and lab seats under the GSA Multiple Award Schedule, and a $500 initial order under SHIELD. The company's GSA Schedule labor portfolio spans 56 active categories with hourly rates from $100.41 (Software Engineer I with associate degree and two years' experience) to $355.70 (HACS Program Manager 5 with bachelor's degree and eleven years' experience), anchored by Highly Adaptive Cybersecurity Operator roles at $102–$192 per hour; no security-cleared positions are offered on the Schedule.

In its subcontractor role, Sixgen delivers penetration testing and vulnerability assessment services to The Aerospace Corporation under the NASA-Wide Specialized Engineering, Evaluation and Test Services (NSEETS) contract as of February 2025. The company also provides cyber forensics, technical analysis, and cyber crime support to the Department of Defense Cyber Crime Center under Peraton Enterprise Solutions primes (awards dated December 2024 and August 2024), and systems engineering and cybersecurity work to the C5ISR Center under a Science Applications International Corporation prime (February 2024). Earlier sub work includes system development and modeling efforts under Radiance Technologies primes supporting the Space Directorate (October 2022 modifications).

Award activity shows variation: three awards in 2021 declining to two in 2022, then growing to five in 2024 and four in 2025 with one award to date in 2026. The Treasury order arriving in June 2026 represents a step increase in ceiling value but does not yet signal sustained multi-customer growth; recompete exposure in the next twenty-four months centers on the Navy Sea Systems Command and GSA Federal Acquisition Service task orders. NAICS concentration leans toward Research and Development in Physical, Engineering, and Life Sciences (5 awards) and Other Computer Related Services (3 awards), with PSC work split between Support—Professional: Other (4 awards) and DOD Military Experimental Development R&D (2 awards).
