Verify Licensing and Insurance First
Every state that requires security company licensing maintains a public registry. Look up the company's license status before you take a meeting. An expired or suspended license means the company is operating outside the law, and any contract you sign with them may be unenforceable if an incident occurs. Ask for the license number upfront — a legitimate company will provide it without hesitation.
Insurance is equally non-negotiable. Request certificates of general liability and workers' compensation coverage. Verify the policy dates, coverage limits, and whether your site would be covered under their existing policy or requires an endorsement. If a guard is injured on your property and the company's workers' compensation is lapsed, the claim lands on your organization.
Confirm coverage is active with the insurer directly, not just by reading the certificate the company hands you. Certificates can be outdated or issued before a lapse. A five-minute phone call to the insurance carrier eliminates a risk that could cost your organization significantly more than the time it takes to make the call.
Evaluate Staffing and Training Standards
Ask how the company recruits, screens, and trains its guards. Background checks should include criminal history, employment verification, and drug testing at minimum. Training should cover your specific site type — a retail environment has different protocols than a warehouse, a corporate campus, or a residential community. Generic training programs that do not adapt to the client site produce guards who look present but cannot respond effectively when something actually happens.
Ask about the company's backup staffing plan. When a guard calls in sick at midnight, what happens? A company with a deep roster and a defined call-out procedure covers the gap within a guaranteed window. A company that relies on the same five guards for every account will leave your post empty until morning. The staffing guarantee belongs in the contract with a defined response time, not in a verbal assurance during the sales pitch.
Request information on guard retention rates. High turnover means your site gets a rotating cast of guards who never learn your facility, your tenants, or your emergency procedures. Consistent staffing builds familiarity and situational awareness that no amount of written protocol can replace.
Check References and Performance History
Request references from at least three clients in your industry or site type. Call each one and ask specific questions: How often were posts left unmanned? How quickly did the company resolve complaints? Did the billing match the contract terms? Were incident reports submitted on time and with useful detail? Vague praise is worth nothing — you want concrete answers about reliability, communication, and billing accuracy.
If the company has been in business for more than a few years, look for patterns in online reviews and complaint filings with your state's licensing authority. A single negative review is noise. A recurring theme — high guard turnover, unresponsive management, disputed invoices, or slow incident response — is a signal that the problems are structural rather than isolated.
Use the guard coverage cost estimator on the home page to compare what the company quotes against a baseline model built from your post count, shift hours, and coverage days. If the quote lands far below the baseline, ask what it excludes. Suspiciously low pricing usually means corners are being cut on insurance, training, guard pay, or all three — and those cuts transfer risk from the vendor's books to yours.
Red Flags to Walk Away From
Any company that pressures you to sign before you have completed your due diligence is hiding something. A refusal to provide license numbers, insurance certificates, or client references is a disqualifying red flag that should end the conversation immediately. Pricing that undercuts every other bid by a wide margin usually means the company is cutting corners on training, insurance, or guard compensation — all of which increase your exposure.
Watch for contracts that auto-renew without notice requirements, or that lock you in for multi-year terms with no performance-based exit clause. If the company resists adding a staffing guarantee, guaranteed response time, or an incident-reporting protocol to the written agreement, they are telling you those commitments will not be met consistently when it matters.
Finally, evaluate communication quality during the sales process. If the company is slow to return calls, vague in its answers, or inconsistent in the information it provides before you sign, those patterns will not improve after you become a paying client. The sales phase is when companies put their most responsive foot forward — if that foot is already slow, the service will be slower.
Licensing requirements and insurance standards vary by state — confirm your local regulations before applying this checklist.
