Concentric Security LLC

What Concentric Security LLC does

Concentric Security LLC is a US-based perimeter security solutions integrator and a registered trade name/division of Intellimar, Inc., founded by Mark Oakes in 1995. The company delivers turnkey hostile vehicle mitigation (HVM) systems for government, defense, commercial, sports and entertainment, data center, and critical infrastructure clients through a four-phase Assessment-Engineering-Construction-Service process. Core products include crash-rated wedge barriers, bollards (including exclusive distribution of patent-protected Heald Matador and Raptor shallow-mount lines), barrier arms, perimeter gates, fencing, cable systems, guard booths, and custom programmable logic controller (PLC) control panels. The portfolio is augmented by proprietary S.M.A.R.T. middleware for barrier monitoring and predictive diagnostics, Ferrocast bollard covers, and Intelligent Optical Inspection Technologies for under-vehicle and license plate inspection. As a certified dealer for major brands (Heald, Delta Scientific, Gibraltar, HySecurity, Alvarado, Boon Edam, B.I.G. Enterprises, Par-Kut, Porta-King, Panel Built, Guardian Booth), the company functions primarily as a systems integrator rather than an OEM.

The business operates as a privately held, founder-led B2B/B2G enterprise with roughly 11-50 employees and three US offices (Maryland HQ, Alabama, North Carolina). Revenue is generated through hardware resale, turnkey installation and construction services, and recurring maintenance/service contracts covering 1,500+ barrier units across 350+ sites, with barrier renovation programs offering up to 70% cost savings versus replacement. Federal procurement is channeled through the GSA Federal Supply Schedule (47QSWA22D0019), and notable contracts include a $49M, 5-year Blanket Purchase Agreement with WMATA, plus installations at the Pentagon, United Nations HQ, World Bank, FBI, U.S. Air Force Strategic Command, U.S. Department of State, Smithsonian, and Major League Baseball venues. The 30-year operating history, multiple INC 500 recognitions (2004, 2005), Heald's 2020 Distributor of the Year award, and management team's 75+ years of combined security industry experience underscore an established, credential-heavy position in a niche perimeter security market.
