Security Companies in San Antonio, Texas

Start with what you need covered, since San Antonio company pages range from guard firms to national branches. All of those below state San Antonio coverage on their own pages.

By Security Briefing, an independent publication. Details checked . Listings are not endorsements.

Do I need someone on site, or just patrols?

Fixed posts suit busy sites, while mobile patrol suits closed lots and properties. Ask for each company's options.

How do I check a license?

Texas DPS regulates private security. Use the license search on its licensing page with the company's legal name.

Does a company have experience near military facilities?

Ask directly, and ask for a reference. San Antonio has several military installations, but base access and contracting have their own rules, so a company's general guard experience may not apply.
