About Us

About Custom Security



Onne L. Heeren founded Custom Security in 1977.  What began as a one-man operation has since grown into a business of over 80 people. In the early 90s, our monitoring center was certified by Underwriters Laboratories (UL). Today, Custom Security Systems remains the only Baton Rouge-based UL-listed 24-hour monitoring station. So that none of these ever have to be subcontracted, we also have on-site service, installation, sales, and billing departments.

Custom Security provides security, fire and camera systems for residential and commercial clients. We also provide electronic gates and access control for businesses and homeowners’ associations. In addition, we offer the convenience of smart home/business features like thermostats and electronic door locks.

Our steady growth has given us customers in multiple parishes but we remain in Baton Rouge to be highly accessible. A local person is always available to answer calls, a standard that sets us apart within and outside of the industry.

Baton Rouge is good to us and so we give back to our community by participating in first responder-sponsored events. We are active in the Louisiana Fallen Firefighters’ Ceremony, Night Against Crime for BRPD, and other events throughout the year.

Honeywell has recognized Custom Security Systems with Technical, Life Safety, and Community Service Awards. SDM (the security industry’s leading magazine) consistently lists us as one of the Top 100 Security Dealers in America.

Custom Security has the perfect balance of a company that embraces new technologies while keeping alive customer care principles established by our founder, Mr. Heeren.
