 Trustindex verifies that the original source of the review is Google.  I had a Respectful and Professional experience with Guardian Security Services. Although the site was far North, I was physically checked on and asked several times if I needed anything. Site Supervisors Shirley, Tim are Awesome Leaders and Teachers. Management and Human Resources answered any and all questions in a timely manner and were patient and kind to me. If you don’t like to be held accountable for your actions/rules this is not the place for you. Thank You S/O A.Fryer

 Trustindex verifies that the original source of the review is Google.  I live in an upscale residential building in downtown Chicago.  I have confidence our building is secure and safe.  Our guards are very polite and helpful, always by the book.  Someone tried to gain access to our building and the officer was professional yet assertive when needed, making the policy known to the person in a clear, definitive manner.

A Legacy of Client Satisfaction

Our long-term partners share their stories of consistency, professionalism, and care that define Guardian Security’s commitment to service.

The team at Guardian is performing excellently from top to bottom. We have the right guys in the right places. David, is a pleasure to work with and contributes immensely to the team's performance. Whether it be for after-hours calls, odd requests, or even being willing to meet with us weekly. Not only do you make the security services here a comfortable and stress-free topic for Management, but our residential building would be far worse off if we had anyone else supervising our property or a different firm managing. I hope the building never has to see the day. Again, thank you for all that you do. It does not go unnoticed.

I am new to the Guardian Security experience. Being a Property Manager, we are often concerned about making the correct recommendations to our Boards. The staff that has been placed at my guardhouse has made me look like a hero in the eyes of the Board. It is always a pleasure to interact with the guards, as well as the office staff. Their customer service is stellar. Their professionalism is stupendous. I am looking forward to a long relationship. Should I ever pick up another gated property, you can be sure I will get Guardian aboard. Thank you for making my job easier.

I have had the opportunity to work with many of the larger nationwide security firms throughout my career and working with Guardian Security has been a breath of fresh air. I have been most impressed with the professionalism of the officers assigned to our facility.

On behalf of myself and the community, I want to express my gratitude to you and our Guardian team. Guardian Security has been our 24/7 security provider since 2015, and I am heartened to say that switching firms have proven to be an excellent decision.

As a property management company, we are always looking for a sound relationship and exemplary service for our customers. We have found that with Guardian Security! Currently, the Guardian Team provides service for 5 gated communities in the western suburbs for the past seven plus years.

Guardian Security Services has partnered with our bank since 2009. I have had the personal pleasure of working with Guardian for the last five years as the bank’s head of security. Guardian’s team provides the best service and will always go above and beyond to make sure our security needs are met.

Guardian Security is the first security company I’ve worked with that gave me peace of mind. I don’t need to be in constant communication with them because the very few times there are challenges, they are handled swiftly and appropriately by their entire team; which helps us all sleep better at night.

Guardian Security stands out above the rest. Coming from onsite union staff and from other third party security firms, I would use Guardian as my first choice at any building I manage in the future.

Guardian Security has been our Security Provider for more than eight years now and I must say that the security operation continues to improve and respond to the ever-changing environment.

Guardian has served our homeowners association as their premiere security company for the last ten years. They have been far superior to our previous security company, and in our opinion, they are one of the best.
