What we protect
Every property has its own risks, so we plan our security guard services around yours, with unarmed officers, armed security guards or a mix of both.

Why clients stay with us
Three things you can check before you sign, and count on for as long as we're on site.
You know who is on your site before they take their first shift
Every officer passes a criminal background check and fingerprinting before we hire them, not after. Each one is also certified, insured and bonded before they're placed on your property.
You get coverage planned around your property, not a one-size package
We start by assessing your property for free. Whether that points to a single unarmed officer or armed guards on every shift, the plan comes out of that visit, and the price follows the plan rather than the other way around.
You can reach a real person at any hour, including nights and holidays
Our dispatch line is staffed 24/7, so your call never ends up in a voicemail box. Supervisors are local to the sites they cover, so when something happens, you're dealing with someone who already knows your property.
