Trellix Public Sector LLC

Trellix Public Sector LLC, a McLean, Virginia-based cybersecurity solutions provider, operates as a prime contractor on endpoint security and cloud-management software contracts with the Department of Defense and as a subcontractor to defense primes on classified and unclassified programs. The vendor competes full-and-open (no set-asides) across all recent prime awards. Trellix is a for-profit limited liability company and manufacturer of goods; the source does not identify SBA ownership designations or minority-owned status.

Trellix's prime footprint (31% of recent awards) centers on commercial-off-the-shelf endpoint security system (ESS) software subscriptions, maintenance, and support. The most substantial holding is a $151 billion, 10-year multiple-award IDIQ contract awarded by the Missile Defense Agency on December 29, 2025, under the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program, spanning research and development, prototyping, systems engineering, cybersecurity, and modernization across classified and unclassified programs with initial delivery order of $500 issued through December 28, 2035. Trellix also holds a single-award $20 million five-year IDIQ with the U.S. Army Communications Electronics Command (CECOM) running through September 2030 for Trellix ESS software subscriptions and related services supporting Army cybersecurity operations. Three delivery orders totaling $2.6 million have been issued under the CECOM IDIQ as of January 16, 2026: a $295,867 award for ESS software maintenance and Platinum support (September 26, 2025), a $162,512 award for commercial-off-the-shelf software license subscriptions (December 31, 2025), and a $2.13 million award for ESS subscription renewal (January 16, 2026).

Customer concentration diverges between volume and dollars. By award count, the Navy's Naval Air Systems Command (NAVAIR) dominates with nine awards, but by potential value the Army's CECOM anchors the portfolio at $22.6 million across four awards (88% of total potential value across the top customers). The Missile Defense Agency accounts for six awards but only $500 in potential value (placeholder order). Naval Special Warfare Command, Army Materiel Command's Research Development and Engineering Command, and Army Pacific Command round out the federal customer set (23 of 26 awards captured in the top-customers block). Trellix operates under multiple parent vehicles: the W58P0525D0009 CECOM IDIQ carries three task orders ($2.6 million combined), HQ085224D0003 carries four task orders (likely NAVAIR F-35 sustainment work based on sub-award scopes), One Acquisition Solution for Integrated Services (OASIS) carries two task orders, and Alliant II carries two task orders.

The vendor's sub footprint (69% of recent awards, 18 sub awards) concentrates on endpoint protection, cloud workload security, policy auditor, and device-control software delivery to Lockheed Martin (ten sub awards, primarily on F-35 air system sustainment), Smartronix (three sub awards supporting U.S. Special Operations Command Pacific C5ISR missions), ECS Federal (one sub award, AESS 2.0 endpoint protection labor), and Leidos (one sub award providing incremental funding for goods and services). The SCI dataset shows Trellix reported 23.1 FTEs in FY2022 across 25 sub records, indicating the vendor operates primarily as a subcontractor for labor and software licensing bundled into larger defense primes' program delivery — the 160% obligations-to-potential-value ratio (obligated $37.4 million against $23.4 million potential value) reflects task order exercising and modification activity outpacing initial ceiling values. Three awards (combined potential value $2.6 million) face recompete within twenty-four months, concentrated in the CECOM ordering period. Trellix's capability concentration sits at the intersection of Aircraft Manufacturing (nine awards, NAVAIR F-35 work), Software Publishers (four awards), and Custom Computer Programming Services (four awards), with enduring sub relationships to Lockheed Martin on classified and unclassified defense modernization.
