Frequently Asked Questions

How do I compare security companies?

Use the search box and filters to narrow results by location, service, or company information, then review each company's license status, services, and business details on its profile page. Add companies to your quote list to compare them side by side.

What does an active license listing mean?

An active license listing means the company's state security license -- such as California's Private Patrol Operator (PPO) license -- was current as of our latest verification, sourced from the issuing state agency.

Does a company address indicate its complete service area?

No. Location filters match a company's registered business address. Some companies also report specific service areas on their profile, but an address alone does not confirm every area a company is willing to serve.

How does the quote list work?

Add companies to your quote list directly from a result card or a company profile. Your list is saved so you can review, compare, and request quotes from multiple companies at once.

How are company services verified?

Services shown on a listing are drawn from a company's public website when available, or from licensing records when no verified website information exists. Companies without confirmed service details show a general fallback description instead.
