Kastle Systems LLC

Kastle Systems LLC, a Falls Church, Virginia-based for-profit limited liability company, delivers physical security infrastructure and operations-and-maintenance services to federal civilian agencies as a prime contractor under full-and-open competition, with no SBA certifications and no subcontractor relationships across its federal award footprint.

Kastle competes almost exclusively on the GSA Multiple Award Schedule (MAS), where it holds two principal federal supply schedules. The vendor's capability portfolio centers on access control systems, video surveillance and closed-circuit television operations, identity management infrastructure (including Personal Identity Verification card reader certification and maintenance), and integrated facility security system operations and monitoring. Representative prime work includes a $1.6 million delivery order from the Small Business Administration's Office of the Chief Operating Officer for maintenance and operations of physical security access control systems across Washington, DC and satellite locations (New Orleans and Herndon), running through July 2027; a $639 thousand delivery order from the Department of the Interior's Fish and Wildlife Service for operations and maintenance of the headquarters Skyline Electronic Security System in Falls Church through February 2030; and a $586.8 thousand Federal Election Commission delivery order for access control and security systems operations and maintenance through June 2028. Kastle also holds an incumbent sole-source relationship with the Commodity Futures Trading Commission for access control and video operations and maintenance across headquarters and regional offices, with multiple overlapping task orders totaling approximately $890 thousand in combined potential value.

Kastle's customer base is broad but concentrated in civilian agencies. The top five customers by potential value — Securities and Exchange Commission ($30.2 million across 27 awards), Department of the Treasury Departmental Offices ($4 million across 15 awards), Small Business Administration Office of the Chief Operating Officer ($3.9 million across 11 awards), Commodity Futures Trading Commission ($2.4 million across 19 awards), and Treasury Inspector General for Tax Administration ($1.3 million across 15 awards) — account for 33 percent of combined potential value across 121 distinct customer agencies. By award count, Treasury IRS leads with 47 awards totaling $751 thousand, followed by the Securities and Exchange Commission with 27 awards worth $30.2 million; the disparity reflects the IRS's reliance on smaller, recurring task orders against the MAS while SEC task orders carry higher individual ceiling values. Kastle has served 121 distinct federal agencies over its award history, with particularly strong penetration among financial regulatory and civilian administrative agencies.

Kastle operates exclusively as a prime contractor; its 826 total awards over its recorded history are 100 percent prime, with zero sub-award relationships in the source data. The vendor's recent activity has remained relatively stable — 14 awards in 2022, 10 in 2023, 9 in 2024, 13 in 2025, and 9 awards through October 2026 — but the combined potential value across all awards sits at approximately $125 million with only $49.3 million obligated to date (39 percent), indicating a substantial pipeline of option years and task orders not yet funded. Fifteen awards (combined potential value $5.6 million) reach ultimate completion within the next twenty-four months and face recompete exposure.

The vendor's work is grounded almost entirely in two NAICS categories: Security Systems Services (except Locksmiths) with 364 awards and Automatic Environmental Control Manufacturing for Residential, Commercial, and Appliance Use with 351 awards. Across PSC codes, the portfolio is dominated by Miscellaneous Alarm, Signal, and Security Detection Systems (317 awards) and Maintenance/Repair/Rebuild of Equipment — Alarm, Signal, and Security Detection Systems (99 awards), with smaller pockets of support and communications security work. SCI-reported invoiced revenue is minimal — only $903 thousand in FY2022, with zero reportable invoicing in FY2023–FY2025 — a reflection of the fact that most of Kastle's federal work falls below the $150 thousand SCI reporting threshold or consists of micro-purchases and firm fixed-price delivery orders that do not trigger labor-hour reporting. The vendor reports zero FTEs across all SCI records, consistent with its delivery-order-based service-contract profile. GSA labor rates shown in the source carry placeholder pricing ($0.00/hr) and do not reflect actual charged rates; the source does not provide actionable labor-rate intelligence.
