in the East Bay
Complete security for every property
From marked mobile patrols to dedicated on-site officers, we tailor coverage to the way your property actually operates.
The dependable presence your property deserves
Security only works when it shows up — consistently, visibly, and accountably. That's the standard we hold every shift to. We don't just observe and report; we prevent and protect.
Visible deterrence
Marked vehicles and uniformed officers make it obvious your property is protected — most threats leave before they start.
Always reachable
Real people answer, day or night. You get a direct line to the team protecting your property, not a call center.
Documented accountability
GPS-tracked patrols and time-stamped reports mean you always know exactly what was checked, and when.
Licensed professionals
Every officer is licensed, background-checked, and trained to represent your business with professionalism.
