Maine's single-source security partner since 1997
Commercial electronic and physical security integration for Maine's financial and business sectors — designed, installed, and serviced by our own licensed local technicians.
What we do
Most security companies handle alarms or equipment. We do both — so you get one accountable partner for your entire security platform.
Video surveillance, access control, and intrusion detection — engineered as one integrated package, backed by 24-hour UL-listed monitoring.
The fixed equipment that protects cash, documents, and daily transactions — sold, installed, and serviced by our own team.
Who we serve
Complete branch security — from vault doors and undercounter steel to integrated alarm, video, and access platforms. We're the single source Maine banks and credit unions rely on.
Customized systems for offices, retail, restaurants, schools, and medical facilities — sized to your needs and your budget, with no long-term contracts. The same security we build for banks, fitted to your business.
