Security Systems Services (Except Locksmiths)

NAICS 561621 · Federal Contracts & Awards

$100,227,046.35 is the USAspending.gov obligation sum for Security Systems Services (Except Locksmiths) (NAICS 561621) in FY2026. About 2.8 percent of a 3.5-billion-dollar security-systems extract sits on this early FY2026 cell. Six thousand five hundred sixty-seven industry-extract awards make 561621 a thick services parent, not a FY2026 alarm-account census. That pair is Security Systems Services (Except Locksmiths) (NAICS 561621) and federal fiscal year 2026 — not every federal dollar in FY2026, not Security Systems Services (Except Locksmiths)'s $3,526,034,037.08 extract-wide book, and not cash already paid. The cell is 2.8% of this industry's published obligation total. 6,567 is the industry-extract award-record count, not a FY2026-only instrument tally. USAspending.gov is the source. Correlation is not causation.

Key figures

  • Security Systems Services in FY2026: $100,227,046.35 in USAspending obligations (NAICS 561621).
  • That cell is 2.8% of the industry's $3,526,034,037.08 extract-wide total.
  • 6,567 is the industry-extract award-record count, not a FY2026 census.
  • NAICS 561621 × FY2026 is an obligation join, not an outlay and not a named-recipient list.
  • Cite USAspending.gov; quote /industries/561621/ and /fiscal-years/2026/ if live tables moved.

The two-key cell: security systems services (except locksmiths) in FY2026

NAICS 561621 and fiscal year 2026 meet here. $100,227,046.35 is the USAspending.gov obligation sum on the yearlyTrend row that carries both tags. It is not Security Systems Services (Except Locksmiths)'s nationwide all-year total of $3,526,034,037.08, not every federal dollar coded to FY2026, and not an outlay register. The packet does not split alarm monitoring from installation; locksmiths are excluded by NAICS definition. 6,567 is an industry-extract action count: modifications and repeat awards add rows across years. Unique recipients are unpublished. This cell is not an alarm-account census, a named-vendor roster, or a device-install log.

Open /industries/561621/ (NAICS 561621) for the industry table without this FY2026 filter, /fiscal-years/2026/ (FY2026 federal spending) for the year table without this NAICS filter, /industries/ (All industries) for every industry, and /ties/ (All spending ties) for the rest of the join list. Quote those hubs as parents, not as addends to $100,227,046.35. Security-systems services (561621) are not investigation-and-background-check services (561611).

This page reports security systems services (except locksmiths) activity USAspending tagged to FY2026. The headline $100,227,046.35 sits beside an industry-wide obligation total of $3,526,034,037.08; the 2.8% share is arithmetic on those two packet facts, not a ranking of fiscal years as winners or losers. Obligations are not outlays. Vendor names and device counts are unpublished. Quote 561621 and FY2026 together.

Security Systems Services is the industry key, not a program name

USAspending labels NAICS 561621 as Security Systems Services (Except Locksmiths). That code produced $100,227,046.35 when crossed with fiscal year 2026. The industry-wide 561621 hub does not require a FY2026 filter. The year hub does not require Security Systems Services. Only this tie applies both filters. The packet does not split alarm monitoring from installation; locksmiths are excluded by NAICS definition. Locksmiths are excluded by the NAICS label as written. This page will not add them back.

Questions

How much Security Systems Services spending is obligated in FY2026?
USAspending.gov lists $100,227,046.35 in Security Systems Services (Except Locksmiths) (NAICS 561621) obligations for FY2026. That yearlyTrend amount is 2.8% of the industry's $3,526,034,037.08 extract-wide total. It is an obligation join, not an outlay and not every federal dollar in FY2026. Unique recipients are unpublished.
Is $100,227,046.35 the entire Security Systems Services USAspending total?
No. NAICS 561621's extract-wide total is $3,526,034,037.08. FY2026 is 2.8% of that book. Other fiscal-year rows for the same industry are separate cells. Do not add /industries/561621/ into this join. 6,567 award records stay on the industry extract, not on this yearlyTrend row.
Is $100,227,046.35 cash already paid in FY2026?
No. Obligations are commitments recorded on USAspending.gov awards. Outlays — money that actually left the Treasury — are a different concept and are not this packet's headline. Treating $100,227,046.35 as checks already cleared in FY2026 confuses those terms. Prefer the live industry and year hubs if the tables moved.
Are FY2026 figures final?
Not necessarily. The source note says FY figures can be incomplete for the current year. $100,227,046.35 is the published yearlyTrend amount for NAICS 561621 in FY2026 on this snapshot. Prefer /industries/561621/ and /fiscal-years/2026/ if live tables moved. Outlays are unpublished.

USAspending.gov NAICS yearlyTrend by fiscal year. Obligations are not outlays. FY figures can be incomplete for the current year.
