Company profile
researched Aug 2026Bannerman operates a platform through which businesses book and manage contract security guard services. Customers can confirm guard coverage or request a quote, and then view and edit guard schedules from a web dashboard. The company positions itself as combining a contract guard network with software for an industry it describes as traditionally low-tech.
The platform consolidates security operations functions in one place, including management of post orders, real-time reporting, centralized communications and automated billing. Real-time GPS tracking is offered so clients can see a guard's patrol, shift and location. Bannerman states that every guard in its network is screened, licensed, insured and certified, and that clients can select among security providers to match pricing and coverage needs. In addition to buyer-facing services, the company runs a program for security firms to become security partners on the network.
Business model
Bannerman acts as an intermediary between businesses needing guard coverage and contract security providers, pairing deployed guard services with a software dashboard for scheduling, reporting, communications and automated billing. Security companies can join the network as security partners.
