Safety for All Communities

While every community deserves to be safe and secure, there are several types of communities that should pay close attention to their security plan.

Some of these include:

Condominium Associations: Condos benefit from a firm access control system that keeps track of who goes in and out of the building. Defender One Security can help set up new and existing condos with a robust system.

Apartment Complexes: Depending on the property, apartment complexes can utilize a wide array of security solutions to protect their tenants. From foot patrols to surveillance cameras, our guards can craft a solution to fit the needs of your property.

55 and Older Communities: Communities for older populations greatly value safety and security for themselves and their grandchildren. Defender One Security can offer a professional and friendly visible presence that will make everyone feel at ease.

Government Subsidized Housing: Defender One Security understands the importance of protecting those in need of affordable housing. We offer a range of security solutions for government subsidized housing, including access control, surveillance cameras, and foot patrols.


We are committed to ensuring the safety of your community and its residents.
