About Us
Started in 1984, Knight Security Inc. has been Western South Dakota's and Eastern Wyoming's trusted name in security for over 28 years.
We are proud to be a small business in Rapid City, offering the only local monitoring in the area and providing quality work from the sale, to installation, to service.
We view each potential sale as the start of an ongoing relationship. We take the time to meet with you, discover your needs, view your property, and find your best security solution.
Even after trained technicians install your system and show you how to use it, our job is not over. Should a question arise or your system need servicing, we follow through on our work.
While other security companies often outsource their monitoring, at Knight Security we monitor each account 24/7 from our office in Rapid City. A real person will take prompt action should a signal be sent from your property.
It is important to choose a security company you can trust. Knight Security is licensed, insured, and a member of the Better Business Bureau.
