About
About MNB Security
MNB Security is a low-voltage security contractor based in the Greater Toronto Area. We install, service, and maintain access control, CCTV, alarm systems, intercoms, gate systems, structured cabling, and fiber — for commercial properties, multi-residential buildings, and industrial facilities.
We handle the full scope of work. That means door prep, conduit, cable pulls, device mounting, panel programming, and network configuration. One crew, one point of contact. No subcontractors for the hard parts.
We've completed projects for municipal facilities, logistics hubs, and healthcare environments across the GTA — typically through general contractor networks. If you're a GC scoping a low-voltage package, or a property manager looking to upgrade building security, we're set up to handle the job.

Partnerships
We work alongside Idea Networks on projects that combine security infrastructure with broader IT and network requirements. This partnership lets us take on larger-scope jobs while keeping a single point of accountability for the low-voltage work.
