Why Sentry

Many security companies treat their customers like a number. At Sentry, we know our company would not exist without our customers. That’s why when you call Sentry; our phone is answered by people, not machines. Our friendly service operators answer your questions or find someone who can. We schedule sales, installation, and service calls within hours or days, not weeks. It’s a simple thing, but we believe people like doing business with people, not automated attendants. With Sentry as your security partner, you can feel safe knowing we will be there for you.

As Chicago’s hometown security company, we pride ourselves on a high level of customer service, customized solutions that work perfectly in your business, and the “human touch” that sets us apart from our competitors. We take the time to get to know you and your needs, and let you get to know us by answering the phone ourselves. Our security solutions are developed based upon your needs, not what is easiest for us to install and service. Protecting your business is an important responsibility, and we care enough to be there for you.
