Diamond Security, Inc.

Diamond Security, Inc., a Black American-owned, SBA 8(a) certified small disadvantaged business based in Windsor Mill, Maryland, is an exclusive prime contractor delivering physical security infrastructure—including access control systems, video surveillance, intrusion detection, locksmith services, and design-build security upgrades—to federal civilian and defense agencies under 8(a) sole-source and competitive set-asides, as well as full-and-open task orders against established indefinite delivery vehicles.

Diamond Security operates as a 100% prime contractor with no subcontract footprint. The vendor competes predominantly under 8(a) set-asides: across the recent award portfolio, 8(a) sole-source designations dominate the IRS contract work and account for the majority of the dollar value, with occasional full-and-open task orders from Navy and other agencies. The company also holds Department of Transportation Certified Disadvantaged Business Enterprise (DBE) status. Primary NAICS categories are 561622 (Locksmiths) and 561621 (Security Systems Services except Locksmiths), with secondary construction exposure under NAICS 236220 (Commercial and Institutional Building Construction).

Customer concentration is extreme and IRS-anchored. The Internal Revenue Service accounts for 14 awards carrying $70.8 million in combined potential value—86% of the vendor's total portfolio value across 97% coverage of top customers. The next largest customer, Navy Naval Facilities Engineering Command, carries only $4.7 million across 7 awards. Navy Installations Command places 16 awards but with modest dollar density ($2.9 million combined potential value), reflecting routine maintenance and locksmith call work. Department of Veterans Affairs, General Services Administration, Customs and Border Protection, Immigration and Customs Enforcement, and National Oceanic and Atmospheric Administration round out the active customer set with single-digit award counts and sub-million valuations each.

The vendor's vehicle position reflects this customer concentration. The $49.9 million Blanket Purchase Agreement with the IRS for design-build security systems installations (valid through August 2028) dominates the vehicle footprint—24 task orders under that single BPA carry only $1.2 million in combined potential value at the time of the source snapshot, suggesting that the ceiling remains largely uncommitted. Secondary Navy Indefinite Delivery Contracts for locksmith and routine facility services produce N4008515D7606 (24 task orders, $1.2 million), N0018920D0013 (5 task orders, $602 thousand), and N0018917D0061 (3 task orders, $487 thousand). These vehicles position Diamond Security to respond to task-order opportunities in both civilian facility upgrades and military installation support.

Recent activity is modest and contract completions near-term. The vendor averaged 5.25 awards per year over 2021–2025, with a near-flat trajectory: 9 awards in 2021, declining to 4 in 2025. Two awards with combined potential value of $3.2 million reach ultimate completion within the next twenty-four months, representing recompete exposure of 4% of the portfolio's combined potential value. The December 2025 award for security camera purchase and installation at Joint PEO Chemical and Biological Defense ($21.7 thousand) and the September 2025 IRS Andover air handling unit design-build task order ($563.6 thousand) illustrate the vendor's current work scope: small to mid-sized facility upgrades with firm fixed pricing.

Service Contract Inventory data captures only five years of activity and reflects a narrow federal footprint. SCI-reportable invoiced revenue of $3.4 million in FY2022 involved 2.5 full-time equivalents at government-paid median hourly rates around $406/hr, with senior labor pricing through $526/hr. FY2023 and FY2024 show zero SCI-reportable invoicing and zero FTE activity in the dataset, indicating either an absence of reportable service contracts above the $150,000 threshold in those years or a shift toward purchase-order and small-dollar work below SCI visibility. Across prime contracts captured in SCI, subcontractors represented approximately 10% of total contractor hours, and the vendor named two subcontractors, suggesting a predominantly direct-delivery operating model with minimal leverage.

The portfolio skew toward IRS sole-source awards—both the $49.9 million BPA and numerous definitive contracts for CCTV upgrades, access control systems, high-voltage equipment replacement, and security turnstile installations at IRS buildings in Philadelphia, Andover, Washington D.C., and Richland—indicates strong incumbent positioning with a single large civilian customer but limited diversification. Competitive exposure is confined to Navy routine maintenance and occasional full-and-open facility work with DHS Customs and Border Protection and other smaller agencies. The absence of defense primes, IT contractors, or GWAC seats outside the IRS vehicle suggests limited teaming pipeline for larger prime contractors seeking security subcontractors.
