25 Years Protecting Michigan Businesses
When you hire a security company, you’re trusting them with your people, your property, and your reputation. That decision deserves more than a sales pitch from a national chain. Like our clients, our reputation is most important and is essential that our service supports and upholds our reputation every day, every shift.
Alimar Security is a family-owned, faith-based company headquartered in Warren, Michigan, and licensed in the state since 2001. For 25 years we’ve protected banks, credit unions, schools, retail centers, construction sites, gated communities, and event venues across Detroit and Southeast Michigan. We’re members of the Michigan Association of Security and Investigative Professionals (MASIP), and we hold our officers to the standard that membership implies.
What does local and family-owned actually mean for you? It means the person answering your call has authority to act. It means same-day coverage within hours, not a 48-hour corporate intake process. And it means our name is on every officer we deploy — so supervision, communication, and accountability aren’t add-ons. They’re the business.
Real Guards + Real-Time AI: Smarter Security, Backed by Experience
Most security companies make you choose: cameras or guards, technology or judgment. We don’t believe in either/or.
Alimar combines trained officers with AI-enhanced monitoring that detects threats the moment they develop — motion detection, license plate recognition, facial match, and behavior alerts, running 24/7. When the technology flags something, our professionals respond, verify, and act. The AI never gets tired. Our officers never stop thinking. Together, they close the blind spots that let incidents happen.

Our Services
