What Insurance Does a Security Guard Company Need?

By OnPost Insurance · Updated July 2026

1. General Liability Insurance

General liability (GL) is the foundation of a security company's insurance program and the coverage every client contract asks about first. It pays for third-party bodily injury and property damage claims arising out of your operations — a visitor injured at a post you control, property damaged during a patrol, a slip-and-fall a guard allegedly failed to prevent.

Standard contract requirements are $1 million per occurrence / $2 million aggregate, with your client named as an additional insured. Larger commercial and government contracts often layer an umbrella on top for $5M total limits.

2. Assault & Battery Coverage — The One That Actually Matters

Here is what most guard-company owners don't learn until claim time: the single most common lawsuit against a security firm is an excessive-force or assault allegation, and many general liability policies exclude assault & battery entirely — or cap it at a tiny sublimit like $25,000.

When you compare quotes, this is where cheap policies hide their savings. A policy that's $1,500 cheaper but carries a $25K A&B sublimit is not cheaper — it's uninsured for your #1 exposure. We quote policies with full or meaningful A&B limits and show you the sublimit in writing before you buy.

3. Workers Compensation

Required by law in nearly every state once you have W-2 employees. Security guard class codes carry real injury exposure — altercations, foot patrols, night work — so comp pricing varies widely between carriers. This is often where our 30% average savings comes from: putting your payroll in front of carriers that actually want security class codes instead of surcharging them.

4. Errors & Omissions (Professional Liability)

E&O covers claims that your guard service failed to perform: a guard who missed rounds before a break-in, failure to detect, failure to report, negligent monitoring. These "negligent security" suits don't involve bodily injury caused by your guard, so GL often doesn't respond — E&O does.

5. Commercial Auto

Patrol vehicles need commercial auto — personal policies exclude business use, and a patrol route is unmistakably business use. If guards use their own cars between posts, add hired & non-owned auto (HNOA), which many client contracts now require at $1M.

6. Firearms Liability (Armed Operations)

If any guard carries a weapon, the policy must say so. Many standard carriers decline armed risks outright; getting armed coverage means specialty and surplus-lines markets. We place armed firms every week — see our dedicated armed security guard insurance guide.

7. Supporting Coverages

• Surety bonds — required for state licensing in many states; California PPOs (Private Patrol Operators) must post a ,000 BSIS surety bond alongside general liability. We package the bond with the policy.
• Fidelity bonds / crime — covers employee theft at client sites; increasingly required for concierge and residential contracts.
• Umbrella / excess liability — stacks $1M–$5M above GL and auto for larger contracts.
• Cyber liability — for firms running monitoring centers or storing client access credentials.
