A non-monitored home security system isn't a security system.

If your security system can't call for help, you're putting yourself, your family and your home at risk.

Guardian is committed to your safety.

We NEVER outsource your security:

We have our own 24-hour monitoring center.
We have our own installation professionals.
We have our own customer service professionals
We have our own service technicians.

Our average response time to an alarm is less than 1 minute!

Save up to 20% on your homeowners insurance.
