Diamond Security, Inc.

Diamond Security, Inc., a Black American-owned, SBA 8(a)-certified small disadvantaged business based in Windsor Mill, Maryland, operates as a 100% prime contractor delivering physical security infrastructure and locksmith services to federal agencies under set-aside vehicles. The vendor competes predominantly under 8(a) Sole Source and Total Small Business set-asides, with recent awards across design-build security systems installations, access control and surveillance system upgrades, electronic lock services, and facility infrastructure modernization.

The vendor's capability portfolio centers on physical security design-build work, video surveillance systems (CCTV), electronic access control, intrusion detection, locksmith repair and installation, and related facility infrastructure upgrades including high-voltage equipment replacement and HVAC systems. Representative prime work includes a $2.67 million design-build contract with the Internal Revenue Service for repair and replacement of high-voltage equipment at IRS Headquarters in Washington, D.C. (awarded September 2024, completion September 2026); a $1.69 million 8(a) Sole Source definitive contract with IRS for security and turnstile upgrades at the IRS Federal Building in Philadelphia, Pennsylvania (awarded April 2024, ultimate completion July 2025); a $1.25 million 8(a) Sole Source contract with IRS for installation of electronic access control, video surveillance, and intrusion detection systems across IRS facilities (awarded September 2023, completion June 2025); a $596,696 design-build task order for rooftop air handling unit replacement at the IRS Andover campus (awarded September 2025, completion October 2026); and a $234,014 contract with the Air Force for supply and installation of 231 electronic door locks and access control systems across three dormitory buildings at Joint Base Anacostia-Bolling, Washington, D.C. (awarded September 2025, completion December 2025).

Customer concentration is extreme. The Internal Revenue Service accounts for 67% of the vendor's award count (17 awards) and 91% of combined potential value ($122.5 million), creating significant concentration risk around a single customer. The Department of the Navy Naval Facilities Engineering Command ranks second with 7 awards ($4.7 million potential value), and Navy Installations Command third with 16 awards ($2.9 million potential value). The remaining 20 agencies account for less than 2% of combined potential value. The vendor has served 23 distinct federal agencies across Treasury, Navy, Homeland Security, Veterans Affairs, General Services Administration, and civilian civilian-sector agencies including the National Gallery of Art.

The vendor holds a multi-award $99.999 million Blanket Purchase Agreement with IRS for design-build security systems installations and facility infrastructure upgrades, valid through August 2028, which anchors the portfolio — 24 task orders under this vehicle carry $1.2 million in combined potential value. Additional parent vehicles include three Navy Indefinite Delivery Contracts: a $1.039 million IDC for locksmith services at Navy facilities (N4008515D7606, 24 task orders), an unspecified IDC for miscellaneous Navy work (N0018920D0013, 5 task orders, $602 thousand), and another Navy IDC (N0018917D0061, 3 task orders, $487 thousand). A GSA Blanket Purchase Agreement (2032H823A00009) carries 5 task orders valued at $4.9 million combined potential value for security and facility upgrades at GSA-managed federal buildings.

Activity has moderated in recent years — four awards in 2022, eight in 2023, five in 2024, four in 2025, and three in 2026 — suggesting a flattening trajectory after earlier growth. Only four awards (combined potential value $2.3 million) complete within the next twenty-four months, presenting minimal recompete pressure. The vendor operates as a pure prime contractor with no subcontract footprint across the visible award portfolio. SCI-reported invoicing was $3.4 million in FY2022 on roughly 2.5 FTEs, with zero reported invoicing in FY2023 through FY2025, indicating that most work sits below the SCI reporting threshold or falls outside service contract reporting scope (goods, design-build, classified). Across SCI-captured prime records, government-paid rates ranged from $286/hr at the 10th percentile to $526/hr at the 90th percentile, with a median of $406/hr, reflecting labor-intensive security installation and maintenance work. The vendor reported an average sub-hours share of 7% across prime contracts, with two named subcontractors, signaling a predominantly integrated delivery model rather than a subcontractor-led operation. Diamond Security holds DOT Certified Disadvantaged Business Enterprise status alongside its 8(a) designation, reinforcing its set-aside positioning.
