Who we are
We're a team of licensed security professionals who know the East Bay because we live and work here. From Berkeley's commercial corridors to Oakland's industrial districts and Hayward's retail centers, we understand the real risks local businesses face — and how to prevent them.
Unlike national chains that treat every site the same, we tailor each security plan to the property in front of us. That means the right mix of mobile patrol, on-site officers, and rapid response — and a direct line to the people actually protecting your business.
Every officer we deploy is licensed, background-checked, and trained to act professionally and report thoroughly. When we say we'll be there, we're there.
The standards behind every shift
Visibility first
The best incident is the one that never happens. A visible, professional presence prevents far more than it reacts to.
Genuine accountability
We document our work and answer the phone. You're never guessing whether your property was actually covered.
Professional standards
Licensed, background-checked, and trained officers who represent your business the way you would yourself.
