Armstrong Security places trained, licensed Agents at schools, houses of worship, businesses, and residential properties. We start by understanding your site, then staff it to the standard it needs.
Illinois-licensed private security contractor agency, IDFPR PSCA #122.001579
Every site is different. We staff each post with the tier its risk calls for, so you pay for the protection you need and nothing that you don't.
Armed Agents who observe and report
Licensed armed Agents carrying the full duty load-out. They carry the full use-of-force continuum — OC spray, taser, and firearm — and deter through visible presence, direct people verbally, document what happens, and report it.
How Sentinels workAgents trained to engage a threat
Our advanced tier, trained in counter-terrorism response, combatives, and crowd and riot control — for posts where an Agent may have to act, not just report.
How Protectors workOur highest tier
Every Protector standard, held at 90% or better across two years, plus executive protection training and the judgment complex operations demand. Not great once — great every time.
How Phalanx worksTheir presence allows our staff, volunteers, and community members to focus on the mission, knowing that security is in capable and trustworthy hands.
Daniel SchwartzPresident, Chicago Jewish Alliance
Good security rarely draws attention to itself. Our Agents are trained to deter first, de-escalate when they can, and act decisively when they must.
