Security Company E&O: Why General Liability Will Not Pay for a Failure to Perform

When a client's building is burglarized on your watch, the claim is not bodily injury or property damage. It is a failure to provide the service you were hired to provide, and general liability excludes it.

What does security guard E&O actually cover?

Security errors and omissions covers financial loss a client suffers because your firm failed to perform its services properly. That includes missed patrols, failure to respond to an alarm, inadequate monitoring, failure to detect or report an event, negligent report writing, and failure to follow the post orders in the contract. The damages are usually economic: the client's stolen inventory, their business interruption, their contractual penalties, and their legal fees.

It is a claims-made coverage in most of the market, with a retroactive date, and limits commonly written at $1,000,000 per claim and $1,000,000 to $3,000,000 aggregate. Premiums for a small to mid-size guard company frequently fall between $2,500 and $15,000 depending on revenue, services performed, and whether officers are armed.

  • Missed patrols, checkpoints, and post order violations
  • Failure to respond to or report an alarm or incident
  • Negligent investigation, surveillance, or report writing
  • Failure to detect theft, vandalism, or unauthorized access
  • Client economic loss and contractual damages, not just bodily injury

Why does general liability exclude failure to perform?

General liability responds to bodily injury and property damage caused by an occurrence, defined as an accident. A failure to deliver a contracted service is neither. The client's stolen inventory was taken by a thief, not damaged by your guard, so there is no property damage caused by you within the meaning of the policy. Courts across jurisdictions have consistently held that pure economic loss from a service failure is outside the CGL grant.

General liability forms compound this with several exclusions that hit security firms directly. The contractual liability exclusion removes liability you assumed by contract beyond your common law duty, which is exactly what a service agreement creates. Business risk exclusions remove claims arising from your work not performing as promised. And most CGL policies carry a professional services exclusion, which by itself removes claims arising from the rendering of your security services.

The result is a firm with a $1,000,000 general liability policy and no coverage for the most likely claim it will face. The general liability policy still matters, for slip and falls, for assault and battery where covered, for property damage a guard physically causes, and for the additional insured obligations in client contracts. It simply does not reach failure to perform.

How do alarm monitoring and service contracts limit liability?

Contract terms are the primary risk control in this industry, and well-drafted ones work. Alarm monitoring companies have used limitation of liability clauses for decades, typically capping damages at a small fixed amount such as $250 or $500, or at six months of monitoring fees. Courts in most states enforce these clauses between sophisticated commercial parties, provided they are conspicuous and were not procured through fraud.

Guard service agreements should carry similar protections adapted to the service. Practical provisions include a limitation of liability capped at the annual contract value or a stated dollar figure, an explicit disclaimer that the firm is not an insurer of the client's property, a waiver of consequential damages, a mutual indemnity limited to each party's own negligence, and a requirement that the client maintain its own property and crime insurance with a waiver of subrogation in your favor. That last item is quietly one of the most valuable, because it stops the client's insurer from paying the loss and then coming after you.

The counterweight is that clients negotiate these terms and large clients often strike them. When a limitation of liability is removed, price the account accordingly and make sure the E&O limit reflects the uncapped exposure. Contract review before signature is materially cheaper than litigation afterward.

  • Limitation of liability clauses are widely enforced between commercial parties
  • State clearly that the firm is not an insurer of the client's property
  • Require the client to carry its own property and crime coverage with a waiver of subrogation
  • Waive consequential damages and cap indemnity at each party's own negligence
  • Review any contract that strikes these terms and adjust price and limits accordingly

What limits do client contracts require?

Requirements vary by sector but have converged on recognizable ranges. Commercial property managers and retail clients commonly require $1,000,000 per occurrence and $2,000,000 aggregate general liability, $1,000,000 auto liability, workers compensation at statutory limits with $1,000,000 employers liability, and an umbrella of $1,000,000 to $5,000,000. Healthcare, education, government, and critical infrastructure clients typically require higher umbrella limits, often $5,000,000 to $10,000,000, and increasingly require professional liability at $1,000,000 or more.

Two contract items deserve specific attention. Assault and battery coverage is frequently excluded or sublimited on security company general liability policies, and a client requiring full limits for assault and battery needs to be met with a policy that actually provides it rather than a certificate that implies it. Firearms coverage, where officers are armed, is similarly a named grant rather than an assumption, and unarmed-rated policies do not become armed policies because a client asked for one.

Additional insured status, primary and non-contributory wording, and waivers of subrogation are standard requests and are generally available on general liability and auto. They are usually not available on professional liability, which follows the same market convention as other professional lines.

How do insurers underwrite a guard company?

Underwriters look at four things: what your officers do, who your clients are, how you hire, and how you document. Services are ranked by hazard, with unarmed observe-and-report at the low end, access control and concierge in the middle, and armed officers, bar and nightclub security, crowd control, executive protection, and patrol response at the high end. Firms that mix low-hazard and high-hazard work should expect the whole account to be rated toward the higher-hazard portion unless the split is clearly documented in payroll records.

Client industry matters because it drives severity. Healthcare, schools, residential properties, and hospitality generate higher-severity claims than office buildings and warehouses. Hiring practices are examined closely: background checks, drug screening, state licensing verification, use of force training with documented hours, de-escalation training, and firearms qualification frequency for armed personnel. Annual requalification is the market expectation for armed officers, and many carriers require it as a condition.

Documentation is the last piece and the cheapest to improve. Written post orders for every site, signed by the client. Electronic patrol verification systems that timestamp checkpoints. Incident reports filed within 24 hours. Body camera policies where used. Firms with these systems present better, price better, and defend claims far more successfully, because the record shows what actually happened rather than what each side remembers.
