Government Contracts for Security Companies: Guard Services, Surveillance & Cyber (2026)

TL;DR: Government agencies at every level — federal, state, and municipal — contract out security services worth billions annually. Physical guard services, surveillance system installation, cybersecurity assessments, and access control are all procured through competitive bidding. The key is knowing which NAICS codes to register under and where to find opportunities before they close. Search security contracts on GovBid — free.

The government security market

Security is one of the largest categories of government contracting. The federal government alone spends over $20 billion annually on security-related services, and state and local governments add billions more.

The market breaks into three broad segments:

• Physical security — guard services, patrol, access control, event security
• Electronic security — surveillance cameras (CCTV), alarm systems, intrusion detection, monitoring
• Cybersecurity — penetration testing, vulnerability assessments, incident response, compliance audits

Most security companies start with one segment and expand. A guard services company might add alarm monitoring. A cybersecurity firm might add physical security assessments. Government procurement treats these as distinct services with different NAICS codes, so understanding the classification system matters.

NAICS codes for security contractors

Your SAM.gov registration determines which opportunities you see in federal searches. Register under the wrong codes and you miss contracts. Register under too many and you dilute your profile.

Tip: Register under your primary codes first. You can add codes later as you expand services. Having too many codes with no past performance in them can hurt rather than help.

Types of security contracts

Guard services (561612)

The most common entry point. Federal buildings, military installations, courthouses, and government offices all need guards. These contracts are typically:

• Multi-year — 1 base year plus 2-4 option years
• Labor-intensive — pricing is per guard hour, so your labor rates and benefits package matter
• Clearance-dependent — many require guards with active security clearances
• Performance-based — agencies measure response times, incident reporting, and post coverage

Key buyers: Department of Homeland Security (FPS), Department of Defense, GSA, federal courthouses, Veterans Affairs medical centers.

Surveillance and electronic security (561621)

Agencies procure camera systems, access control (badge readers, biometrics), intrusion detection, and monitoring services. These contracts combine equipment and installation labor.

• Technology refresh cycles — agencies upgrade systems every 5-7 years
• Integration requirements — new systems often must integrate with existing infrastructure
• Compliance standards — federal facilities require FIPS 201 compliant access control
• Maintenance included — most contracts bundle installation with ongoing maintenance

Cybersecurity (541512, 541519)

The fastest-growing segment. Every federal agency must comply with FISMA, NIST frameworks, and zero-trust architecture mandates. State governments are following suit after high-profile breaches.

Common cybersecurity procurements:

• Penetration testing and red team exercises
• Security Operations Center (SOC) services
• Incident response retainers
• Compliance assessments (FedRAMP, CMMC, StateRAMP)
• Security awareness training
• Managed detection and response (MDR)

Note: Federal cybersecurity contracts increasingly require CMMC certification for the contractor itself, not just the end deliverable.

Small business set-asides

Security is one of the strongest categories for small business set-asides, especially guard services. Common set-aside types:

• Small Business (SB) — most guard service contracts under $7M are set aside
• Service-Disabled Veteran-Owned (SDVOSB) — very common for physical security
• 8(a) — sole-source awards up to $4.5M for services
• HUBZone — facilities in designated areas get preference
• Women-Owned (WOSB) — eligible under NAICS 561612

If you qualify for any set-aside category, register it in SAM.gov. Guard service contracts are frequently sole-sourced to 8(a) and SDVOSB firms.

Where to find security contracts

Federal:

• SAM.gov — all federal solicitations. Search NAICS 5616xx for security services.
• GovBid security contracts — AI-filtered security tenders with plain-English summaries, updated daily.
• GSA Schedule 84 — the primary vehicle for security services. Getting on Schedule 84 opens access to task orders.

State and local:

• State procurement portals (Texas ESBD, Pennsylvania eMarketplace, Washington WEBS)
• GovBid Canadian security contracts — for companies operating in Canada

Subcontracting:

• Large security firms (Allied Universal, Securitas, Paragon) often need subcontractors for specific sites or clearance levels.

How to get started

1. Get your SAM.gov registration active. This is mandatory for federal contracts. SAM.gov registration guide.

2. Identify your NAICS codes. Pick 2-3 that match your current capabilities. Don't overreach.

3. Get clearances if needed. Facility clearances (FCL) and personnel clearances take 6-12 months. Start early if you plan to pursue classified work.

4. Start with state and local. Lower barriers to entry, smaller contracts, faster award cycles. Build past performance here.

5. Consider GSA Schedule 84. Once you have 2+ years of past performance, apply for a GSA Schedule. This opens federal task order opportunities.

6. Set up daily alerts. New security contracts are posted every day. Missing a solicitation by one day means missing the opportunity entirely.

Common mistakes

• Bidding without clearances. If the solicitation requires cleared guards, you need them before you bid, not after you win.
• Underpricing labor. Guard service contracts are evaluated on price, but underbidding on wages leads to high turnover and poor performance ratings.
• Ignoring past performance requirements. Most contracts require 3 references for similar work. Start small to build your record.
• Missing the Q&A period. Government solicitations have formal question-and-answer periods. Ask clarifying questions — the answers are shared with all bidders and often reveal evaluation priorities.
