"Extraordinary Experience"

“Our experience with Knight Security has been extraordinary since we made the switch. They always respond to any problem we have within the hour and fix it immediately, they always have the equipment to do the job right the first time.

We never have to worry about the security of our businesses anymore. Keith and his staff are very knowledgeable with what they are doing and keep us up to date on the newest technology to secure all of our businesses.”

"Admirable Standard"

“Knight Security sets an admirable standard for security systems companies.  In my ten years working with Knight, I have interacted with a knowledgeable and helpful office support team. The security monitoring department has been consistently competent and dedicated to my protection. The techs who come out to install or check my system are skilled and good communicators on their area of expertise. All of the above factors have provided for my on-going association and satisfaction with this locally owned and operated business.”
