The Department of Defense's NAICS 561621 (Security Systems Services (except Locksmiths)) market: incumbents, spending trend, set-asides and open solicitations — from FY2026 USAspending awards and live SAM.gov notices.
Contract data as of Oct 18, 2026 (USAspending) · recent coverage verified weekly
| Quarter | Awards | Obligated | Change |
|---|---|---|---|
| Q1 FY2026 | 48 | $102.7M | — |
| Q2 FY2026 | 82 | $14.6M | -86% |
| Q3 FY2026 | 39 | $16.5M | +13% |
| Q4 FY2026 · partial | 21 | $1.9M | -88% |
Federal fiscal quarters (Q1 = Oct–Dec). Awards are counted in the quarter they start; obligations are the award's obligated amount. The Department of Defense publishes contract awards to USAspending with a 90-day delay, so Q4 FY2026 is still missing most DoD awards — treat that quarter as incomplete, not as a spending decline.
| # | Contractor | Obligated | Share |
|---|---|---|---|
| 1 | SERCO HOLDINGS LIMITED | $90.0M | 66.3% |
| 2 | M. C. DEAN, INC. | $7.0M | 5.2% |
| 3 | AKAMAI INTELLIGENCE LLC | $6.4M | 4.7% |
| 4 | JOHNSON CONTROLS BUILDING AUTOMATION SYSTEMS, LLC | $5.9M | 4.3% |
| 5 | ITM4G LLC | $4.6M | 3.4% |
Registrations are rolled up to their corporate parent (USAspending parent UEI), so a company with several SAM registrations ranks once.
