Protecting Northern California Since 1952

In 1952, the Cooke family established All-Guard Systems in the San Francisco Bay Area. Three generations later All-Guard remains family owned and operated. We understand the special concerns of Northern California families, schools, businesses and government agencies – because we live and work in the communities we serve. All-Guard offers a full range of security products and services and we specialize in working with our customers to build customized solutions. All-Guard owns and operates our own UL Listed monitoring center in a secure campus facility in Hayward, California, providing you with the vital link between your security system and the appropriate emergency response agency.

Whether you are interested in security for your home, a small or large business or a high school campus, All-Guard has the solution for you, and we are here for you 24-hours a day, 365 days a year.

“At All-Guard, we recognize that our strength and our competitive advantage is – and always will be – people. People working together to deliver excellence in sales and systems design, technical and administrative support, and monitoring center services. We understand that satisfied customers are essential to our success – therefore, the All-Guard team will remain committed to providing quality products and services, quality people, and above all, total customer satisfaction.”
