Securing Our Community

We protect what matters most

Headquartered in Southfield, Michigan, Guardian Alarm was founded on the principle of protecting those living and working in the communities that we serve. Since 1930, Guardian Alarm has grown to become one of the largest security providers in the Midwest, working every day to help protect families and businesses. From single-family homes to multiple corporate locations, we have the latest technology to secure what matters most.

Our Cultural Values

The Core 8


Do the right thing, even when no one is watching. Our team acts with integrity, accountability, and honesty above all else. Building trust builds a better company.


We communicate openly, honestly, transparently, and with integrity in every connection with both our customers as well as our fellow team members.

Own It

We hold ourselves accountable for our actions and outcomes, both good and bad. We don’t pass the blame.

Have Fun

It’s good to surround ourselves with happy, positive, joyful, and motivated people. We laugh, have fun, collaborate, and celebrate the wins. It’s good for both our team and our company.

One Team

We recognize that we are stronger together. We show up for each other, learn from each other, act with empathy, thrive in a diverse and inclusive environment, and treat each other with respect and kindness not for our own personal gain, but for each other.

Evolve & Adapt

Continuous improvement is an expectation of us by our customers, and we share that expectation of ourselves. It’s a responsibility we embrace daily and never stop pursuing. By acting with the courage to challenge the status quo, we seek to understand and evolve with curiosity and determination.

Customer Experience

Our customers are the lifeblood of our business and they entrust their most precious assets to us. We empower our employees to provide solutions and services that meet or exceed our customers’ expectations every time.

Hire to Aspire

We hire people based on who they are and their talents, not just to fill a job. Our employees are the heart and soul of our business and we invest in development, reward excellence in performance, and help you get to where you want to go in your career.

In Our Community

Staying involved and giving back

Guardian Alarm cares about the communities we serve. We’re actively involved with local chambers and organizations to help give back, engage with those living and working around us, and build lasting partnerships. Each year, we encourage our employees to spend time volunteering, giving back to their favorite non-profit organizations, and engaging with their community.

Great Security Services along with an Application for anyone who is in a hurry. If you have a Smartphone, you can control your home security from your anywhere. The newest feature is FACE ID which can be used with the new iPhone X. While you are in the car, just smile, you can skip the PIN entry and choose Alarm or Disarm. Very convenient. The other feature that I enjoy is that if you forget to set the Security Alarm and move out of a certain area, they call it Geofence, a notification is sent to remind you to set your alarm. Hopefully this won't happen, but if an intrusion occurs or your home loses electricity a notification is sent immediately to your phone. Of course the local law enforcement agency is also informed at the same time. Guardian provides excellent support services that get you thru any unexpected glitches you run into while using the Application.

I am a new customer with Guardian Alarms. This was an install on a new office building. There were delays on the construction of the office and this caused changed install dates with Guardian.They worked with me thru the confusion and everyone I dealt with was professional and competent. I want to recognize one install technician in particular whose customer service was excellent. My hats off to James. He represents your company well.

Guardian Alarm is a company of integrity. They have always been willing to work with me, and has never threatened to disconnect my servicebecause of challenges. I’ve had other alarm companies but Guardian Alarm is the best. I would definitely recommend them to family, and friends.
