About the company
Concentric Security LLC, a Maryland-based small business subsidiary of Intellimar Inc., manufactures and installs perimeter security infrastructure—vehicle barriers, bollards, gates, and access-control systems—and operates as a prime contractor (97% of recent awards) on federal facilities-security and barrier-maintenance work across civilian agencies and military installations. The company competes predominantly under full-and-open and small-business set-aside vehicles, with total small business designations recurring across contracts for barrier maintenance, security infrastructure repair, and installation work.
Concentric Security's customer concentration splits between security operations and defense logistics. The Department of Homeland Security US Secret Service leads both rankings with 20 awards and $6.2 million in combined potential value, followed by the Department of the Army (20 awards, $392 thousand), the Department of the Air Force (19 awards, $574 thousand), and the Department of the Treasury Internal Revenue Service (16 awards, $1.6 million). By dollar magnitude, however, the DoD Washington Headquarters Service ranks second at $4 million across 8 awards, and the National Park Service National Office anchors $3.7 million across 10 awards. The top five customer agencies by potential value account for 15% of combined potential value. Recent representative work includes a $417,878 definitive contract awarded by the Secret Service on September 16, 2026, for barrier maintenance through 2031 (firm fixed price); a $798,840 firm fixed-price contract awarded by the Air Force District Washington on September 30, 2024, for maintenance and sustainment of vehicle barrier and bollard security systems at Joint Base Andrews through 2029; and a $3.2 million single-award indefinite delivery contract with the National Park Service for preventative maintenance and repair of hydraulic bollards and portable barriers at National Mall and Memorial Parks sites through September 2028, which has generated six delivery orders since September 2023.
Concentric Security holds 219 task orders under the GSA Multiple Award Schedule ($27.8 million combined potential value) and sits on several agency-specific indefinite delivery contracts including W911N212D0024 (9 task orders, $265 thousand), 140P3023D0008 (8 task orders, $443 thousand), and HSFE0415D0036 (5 task orders, $501 thousand). Activity has grown from 4 awards in 2022 to 16 in 2025; the company faces 8 awards with ultimate completion dates in the next twenty-four months carrying combined potential value of $5.2 million. The company's award portfolio spans 420 total awards (prime and sub) with combined potential value of $132.9 million and combined obligations of $68.7 million (52% of potential value). Category concentration centers on other communications equipment manufacturing (217 awards) and security systems services (69 awards), with PSC codes dominated by miscellaneous alarm and security detection systems (92 awards) and maint/repair/rebuild of alarm and security detection systems (37 awards).
Concentric Security operates predominantly as a prime contractor and builds delivery capacity through direct hire rather than subcontracting. Across SCI-reportable prime contracts, the vendor retained 83% of hours internally; the company reports 4 named subcontractors across its recorded SCI prime contracts. In its subcontractor role, Concentric Security performs vehicle barrier preventative maintenance and administrative support under M.C. Dean, Inc. on U.S. Marshals Service active vehicle barrier programs and under Emcor Government Services, Inc. on FBI Central Records Complex facilities maintenance. Recent sub awards include work for Balfour Beatty Construction on vehicle barriers at the United States Naval Observatory and multiple task orders under M.C. Dean for National Physical Security Program maintenance and installation across the Marshals Service. SCI-reported invoicing totaled $1.5 million across prime records from FY2023 through FY2025, with $809 thousand in FY2024 across 1.2 FTEs, and government-paid rates on federal service contracts running at a median of $274.26 per hour, with senior labor pricing reaching $398.48 per hour. Activity trajectory shows year-over-year growth through 2025 followed by lighter awards in 2026 so far, though the most recent award (September 2026) is a five-year Secret Service contract, signaling sustained federal customer engagement.
