Buying a Security Guard Business
First, the Qualifying Agent
Security guarding is a licensed trade, and the license decides the deal before price does. Most states require a company-level license, often a Private Patrol Operator or security agency license, and it rests on a qualifying agent: a named individual with the state's required security experience who backs the company's authority to contract guards. If the selling owner is the qualifying agent, the buyer needs a qualified replacement in place at close, or the company legally cannot operate. On top of it, every guard must hold a state guard card, guards must be W-2 employees not contractors, and the company must carry a surety bond and liability insurance. Confirm the qualifier, the guard cards, and the bond first.
Why Searchers Look at Guard Companies
The draw is contracted, recurring revenue: guard companies bill clients monthly under standing post orders, and demand is non-discretionary and growing, pushed by public-safety concerns and thin police staffing. The market is deeply fragmented under a few global strategics, Allied Universal, GardaWorld, and Securitas, so a searcher buys a local or regional book below their attention and can exit to them later. The honest caveat leads into the next section: this is a labor-arbitrage business with thin margins, so the recurring revenue is real but the profit is a spread that must be defended, not a cushion.
What Guard Companies Trade For
Guard companies trade low because margins are thin. Valuation observations put single-state local operators at roughly 2.5x to 4x SDE, profitable diversified single or small multi-state firms at 3x to 5x SDE, and small multi-state platforms at 4x to 6x EBITDA, with regional and premium platforms higher. A searcher is at the SDE end, so anchor there and treat the strategic-buyer platform multiples as the exit, not the entry. Where a business lands is mostly the spread, contract stickiness, and management depth the next section covers; a book of low-margin contracts with the owner scheduling every shift is worth less than its revenue suggests.
The Bill-Pay Spread and Contract Risk
Two numbers and one risk decide a guard company. The first number is the bill-pay spread: the gap between what clients are billed per hour and the fully loaded cost of the guard, wages, payroll taxes, overtime, workers' compensation, and supervision, and that spread is often single digits, so a small wage increase or a client that will not accept a bill-rate pass-through erases the margin. The second is contract concentration: a book leaning on one or two clients can lose most of its revenue on a non-renewal. The risk is turnover: guard attrition runs high, and constant rehiring and retraining is a real cost and a service-quality threat. Read the spread by contract, the client concentration, and the turnover before crediting the margin.
What to Verify in Diligence
The record to assemble before the offer holds:
- The qualifying agent, the company license, and whether the qualifier stays
- Guard cards current for every guard, and W-2 rather than contractor status
- Bill rate versus fully loaded pay by contract, and the real spread
- Client concentration, contract terms, renewals, and cancellation notice
- Guard turnover, overtime reliance, and open post coverage
- Workers' compensation history, experience modifier, and open claims
- Surety bond, general-liability limits, and any litigation
Financeability Notes
Guard companies finance under SBA 7(a), and lenders read contracted, recurring billing favorably, but they underwrite the thin margin and labor risk closely. Expect the lender to want the qualifying-agent transfer resolved, since a company that loses its license cannot bill, and to weigh client concentration and the workers' compensation record. Model debt service on margin that survives a wage increase, and net of a market salary for a scheduler or operations manager if the seller runs the posts, and stress the biggest client rolling off. The margin risk to underwrite is a wage or minimum-wage increase the company cannot pass through to clients, so read the bill-pay spread and the contract escalators, not just the trailing profit.
What the Data Says
Valuation observations put security guard companies at roughly 2.5x to 4x SDE for single-state local operators, 3x to 5x SDE for profitable diversified firms, and 4x to 6x EBITDA for small multi-state platforms, rising for regional and premium scale; directional ranges, not comps, and margins are thin by nature.

Security services M&A regained momentum in 2025 after several flat years, with a fragmented market consolidating under global strategics such as Allied Universal, GardaWorld, and Securitas; advisor data describes healthy sector EV/EBITDA multiples at scale, well above the small-operator SDE range a searcher buys in.
Most states license the company through a Private Patrol Operator or security agency license that requires a qualifying agent with security experience, and every guard must hold a state guard card and be a W-2 employee, with a surety bond and liability insurance required; the qualifier and guard cards must be in order at close.
