Best security company in Chicago with the best rates. When I was told that this company beats any rate and gives A1 service I was definitely sold. TEAM USiA Oh, and the owner is hands on.

Deborah Patterson

I can’t say enough about the professionalism and dedication of USIA Private Security. The staff showed up on time, treated our staff and our guests with the utmost respect and the armed security guard never once presented himself as a threat to anyone, but was welcomed by everyone who was at our event. We cannot thank USIA enough for becoming a new part of our community. I recommend their company to anyone looking for professional security services.

David Orloff

We have been using USIA security services for several years now, and they have been nothing short of excellent! Super reliable, as well as very responsive whenever there have been any security issues. We would highly recommend this company.

Tony centanni

USIA has been a great security partner to work with for our company. The Security officers they get are great with our employees and all of our business needs. Before we used USIA we had some issues with building security and even some theft from employees. Since we have had them all those problems have gone away. SO’s are at the door to make all of our employees feel safe and doing so with a smile on their faces. Our company couldn’t be any happier with the service and professionalism USIA has offered us.

CCS

Great company to work with. Management is personable and responsive. Services are proactive, not reactive, and highly reliable. We've contracted with multiple companies over the years and USIA has provided the best services.

Dave H

Our facility was experiencing missing product on a monthly basis. After describing the issues with USIA, Chris and his team did a thorough analysis of our situation and developed a plan. They were able to identify several areas of weakness and the losses were virtually eliminated in less than a month! We have since added security officers for each of our 3 shifts and we have been loss-free for 10 months! We could not be happier with the results and recently signed a long term contract with USIA.
