Security Services & Protective Force Contracts

The government is one of the largest buyers of security services in the country. The Federal Protective Service (FPS) alone is responsible for protecting roughly 9,000 federal buildings, and most of that protection is delivered by contract guard forces. Add in DoD installations, DOE nuclear sites, VA medical centers, courthouses, and thousands of state and local government facilities, and the market for contract security services runs into the billions annually. But this is a market where margins are thin on commodity guard services and the real money lives in specialized security — cleared guard forces, SCIF protection, cybersecurity consulting, and executive protection. If you run a security company or are thinking about entering government security contracting, this guide covers the landscape honestly, including the parts that are not particularly profitable.

Overview

Government security contracts fall into several categories, each with different requirements, margins, and competitive dynamics. Basic unarmed guard services at a county office building is a different business than providing armed protective force officers at a DOE nuclear facility. Understanding where you fit — and where you want to be — matters more in security than in most other government contracting sectors.

At the commodity end, unarmed guard services for office buildings and parking structures are bid LPTA and margins run 3-8% after wages, benefits, insurance, and overhead. The Service Contract Act sets the wage floor, and everyone prices off the same wage determination. Differentiation is minimal. You compete on price, and you win or lose by pennies per hour.

At the specialized end, armed protective force contracts at DOE nuclear sites or cleared guard forces at classified facilities command significantly higher billing rates and better margins. These contracts require extensive personnel qualifications, security clearances, and specialized training programs that most security companies cannot provide. The barriers to entry are the competitive advantage.

Contract values range from $50K for a small municipal security contract to $500M+ for large federal protective force IDIQs. The typical mid-size security company targets contracts in the $500K-$10M range, usually with base-plus-option-year structures running 3-5 years total.

NAICS Codes & Service Types

• 561612 — Security Guards and Patrol Services: The primary code for contract guard forces, both armed and unarmed. SBA size standard: $29 million annual revenue. This is the most commonly used NAICS for security contracts.
• 561611 — Investigation Services: Background investigations, surveillance, fraud investigation, insurance investigation. Size standard: $25 million.
• 561621 — Security Systems Services (except Locksmiths): Alarm system installation and monitoring, CCTV, access control systems, intrusion detection. Size standard: $29 million.
• 541990 — All Other Professional, Scientific, and Technical Services: Used for physical security consulting, threat assessments, vulnerability assessments, and security program management. Size standard: $19 million.
• 561613 — Armored Car Services: Cash-in-transit, high-value cargo protection. Size standard: $37.5 million.
• 541512 — Computer Systems Design Services: Relevant if your firm provides cybersecurity services alongside physical security. Size standard: $34 million.

Most security companies register under 561612 as their primary NAICS code and add others based on their service lines. If you provide both guard services and security system installation, register under both 561612 and 561621.

Key Programs & Agencies

Federal Protective Service (FPS): FPS, part of the Department of Homeland Security, is responsible for protecting federal buildings managed by GSA. FPS uses contract security guards — approximately 13,000 of them nationwide — through a series of regional contracts often called MegaCenter contracts. These are massive, multi-year contracts covering hundreds of buildings across a geographic region. FPS contracts are among the largest security contracts in the federal government. Competition is fierce, and the incumbents have significant advantages because of the transition complexity involved in replacing guard forces across dozens of buildings simultaneously.

DOE Protective Force: DOE nuclear sites require armed protective force officers with security clearances, often at the Q or L level. These officers protect nuclear materials and classified information. DOE protective force contracts are specialized and high-value, with stringent training requirements including firearms qualification, tactical response, and nuclear material handling awareness. The prime contracts at major DOE sites (Hanford, Savannah River, Oak Ridge, Pantex, Y-12) are worth hundreds of millions over their performance periods.

DoD Installation Security: Military installations use a mix of military police and contract guards. Contract guard services at DoD installations require various levels of security clearances and may require armed qualifications. The Army, Navy, and Air Force each manage their own security contracts through installation-level or regional contracting offices.

U.S. Marshals Service — Court Security Officers (CSOs): The Marshals Service contracts for security officers at federal courthouses. CSOs are armed law enforcement officers who screen visitors, provide courtroom security, and protect judicial officers. These positions require law enforcement backgrounds and specific training certifications.

VA Police and Security: VA medical centers use both VA police and contract security officers. VA security contracts prioritize veteran-owned small businesses under the Veterans First program. If you are a VOSB or SDVOSB, VA security contracts are a natural fit.

State and local government: State capitol buildings, courthouses, public schools, transit systems, and municipal facilities all contract for security services. State and local contracts tend to be smaller and less competitive than federal, making them good entry points for newer security companies.

Licensing & Security Clearances

Security contracting has some of the most fragmented licensing requirements of any government contracting sector. Every state regulates security companies differently, and many contracts require security clearances on top of state licensing.

State security company licenses: Every state requires security guard companies to be licensed. The requirements vary significantly — some states require the company owner to pass an examination and background check, others require specific training hours, and some require financial bonding. If you operate in multiple states, you need a separate license in each one. Do not underestimate the time and cost to obtain multi-state licensing. Some states take 60-90 days to process applications.

Individual guard licenses and registrations: Most states require individual security guards to be registered or licensed. Requirements typically include background checks, fingerprinting, and completion of minimum training hours. Armed guards face additional requirements: firearms training, qualification courses, and separate armed guard permits. These vary widely by state — California requires 40 hours of training plus 16 hours of firearms training for armed guards; Virginia requires different hour counts; other states have their own standards.

Security clearances: Many federal security contracts require personnel with active security clearances. SECRET clearances are common for DoD installation guard forces. TOP SECRET and SCI clearances are required for guard forces at classified facilities and SCIFs. The clearance process takes 3-12 months depending on the level, and only U.S. citizens are eligible. Having a workforce with existing clearances is a major competitive advantage because agencies do not want to wait months for guards to be cleared before they can start work.

POST certification and equivalents: For armed guard positions at many federal facilities, Peace Officer Standards and Training (POST) certification or equivalent state law enforcement training is required. Some contracts accept alternative certifications, but POST or equivalent serves as the baseline for demonstrating firearms proficiency and use-of-force training.

Service Contract Act & Wage Determinations

Security guard contracts at the federal level are covered by the Service Contract Act (SCA, also known as the McNamara-O'Hara Service Contract Act). SCA requires contractors to pay service employees at least the prevailing wage and fringe benefit rates as determined by the Department of Labor for the geographic area where the work is performed.

How wage determinations work: The Department of Labor publishes Wage Determinations (WDs) for each geographic area, listing minimum hourly wages and fringe benefit rates for specific job classifications. For security guards, the relevant classification is typically "Guard I" (unarmed) or "Guard II" (armed). The solicitation will reference the applicable WD, and you must price your proposal using at least those rates.

Why this compresses margins: Because every bidder must pay the same minimum wage and fringe rates, labor cost — which typically represents 75-85% of a security contract's total cost — is largely equalized across competitors. The margin difference between winning and losing bids comes down to overhead efficiency, insurance costs, and how thinly you are willing to price your profit. This is why commodity guard services have razor-thin margins.

Health and welfare fringe: The SCA health and welfare (H&W) fringe benefit rate is a per-hour dollar amount that you must pay on top of the base wage. You can satisfy this through health insurance contributions, cash-in-lieu payments, or a combination. How you structure your H&W benefit directly affects your cost competitiveness — firms that provide health insurance efficiently spend less per hour than firms paying cash-in-lieu at the full WD rate.

Paid time off: SCA also mandates paid holidays (typically 10 per year), vacation days (based on length of service), and sick leave under Executive Order 13706. These paid hours do not generate revenue but cost you wages and benefits. Factor unproductive paid hours into your pricing — they typically add 10-15% to your effective hourly cost above the base WD rate.

Armed vs. Unarmed Services

The distinction between armed and unarmed security services fundamentally changes the economics and requirements of a contract.

Unarmed guard services: Lower barriers to entry, lower billing rates, more competition, thinner margins. Typical unarmed guard contracts at federal buildings pay $20-$35/hour depending on the geographic wage determination. After wages, fringe, insurance, overhead, and taxes, your margin might be $1.50-$3.00 per billed hour. Volume is the only way to make money. You need enough contracts to cover your fixed overhead and still clear a profit.

Armed guard services: Higher wages (SCA armed guard rates are typically $2-$5/hour above unarmed), higher insurance costs (firearms liability coverage is expensive), more training requirements, and more licensing complexity. But billing rates are proportionally higher, and the pool of competitors is smaller because not every company can meet the armed guard requirements. Margins improve to $3-$6 per billed hour.

Insurance implications: General liability insurance for armed security companies costs significantly more than for unarmed operations. Expect to pay $50,000-$200,000+ annually for a general liability policy that covers armed services, depending on your revenue and claims history. Umbrella and excess policies add further cost. This insurance premium is a barrier to entry that keeps some competitors out, which is good for firms that can absorb it.

Where the Real Money Is

Commodity guard services keep the lights on, but specialized security is where companies build profitable, sustainable businesses. Here is where margins and barriers align in your favor.

Cleared guard forces: Providing guards with active SECRET or TOP SECRET clearances commands a premium. Agencies will pay $45-$75/hour for cleared armed guards at sensitive facilities, compared to $25-$35 for standard armed guards. The key is building and maintaining a cleared workforce, which requires facility clearances (FCL) for your company and individual clearances for your employees. The investment in clearances pays back over years.

SCIF and classified facility security: Sensitive Compartmented Information Facilities (SCIFs) have specific physical and personnel security requirements under ICD 705. Providing security for SCIFs requires deep knowledge of Intelligence Community Directives and the ability to integrate physical security, access control, and personnel security into a unified program. This is consulting-level work with consulting-level billing rates.

Cybersecurity consulting: The line between physical security and cybersecurity is blurring. Firms that offer both physical security assessments and cybersecurity services — vulnerability assessments, penetration testing, security architecture review — can pursue larger, more integrated security contracts. NAICS 541512 work pays significantly better than 561612 guard services.

Executive protection: Protecting senior government officials, visiting dignitaries, and high-threat individuals requires specialized training and experience. These contracts are rare and usually sole-sourced or limited competition, but they are lucrative for firms that have the credentials.

Security system integration: Designing, installing, and maintaining access control systems, CCTV, intrusion detection, and perimeter security at government facilities involves technology margins on top of service margins. The hardware and software components of security system contracts generate better margins than pure labor services.

Tips for Security Contractors

• Get your state licenses squared away before bidding. A missing state security license will disqualify your proposal. Maintain current licenses in every state where you plan to compete. Keep renewal dates on a calendar — a lapsed license even briefly can be a disqualifier.
• Obtain and maintain a facility security clearance. If you want to compete for the higher-value cleared security contracts, you need an FCL. This requires sponsorship from a federal agency or a cleared prime contractor. Start the process early — it can take 6-12 months.
• Build a cleared workforce proactively. Hire veterans and former law enforcement officers who already hold active clearances. Cleared personnel are your most valuable asset in security contracting because agencies will not wait months for guards to be cleared. A roster of cleared, qualified personnel is a competitive weapon.
• Price SCA contracts carefully. Work through the full cost build-up: SCA base wage, H&W fringe, FICA, SUTA/FUTA, workers' comp, general liability, paid leave, uniforms, equipment, overhead, and profit. Missing a single cost element can turn a winning bid into a losing contract. Use a detailed pricing spreadsheet that captures every loaded cost component.
• Do not compete solely on price for commodity guard work. In LPTA guard service contracts, the margins are already razor thin. If you are winning bids because you are the cheapest, you are probably underpricing. Instead, focus on contracts that value quality — best-value procurements where your training program, supervision model, and quality control plan can earn you higher technical scores.
• Move toward specialized services. Use commodity guard contracts to build past performance and cash flow, but invest in capabilities that move you up the value chain: cleared personnel, armed guard programs, security system integration, cybersecurity. That is where the margins support a sustainable business.
• Target SDVOSB and VOSB set-asides. Security contracting has a high concentration of veteran-owned businesses, and many security contracts — especially VA contracts — are set aside for SDVOSBs and VOSBs. If you qualify, these set-asides significantly reduce your competition.
