What if you knew that—no matter where you were or what you were doing

Meet SimpliSafe’s industry-leading professional monitoring.

24/7 Protection

Our monitoring centre is always available. Ready to dispatch help in any emergency.

Disaster Ready

We’ve got 6 monitoring centres. So if one goes down, you’re still covered.

Illustrations Alert

Confirmed Alerts

We send an alarm signal until the monitoring centre confirms they got it.

Authorities alerted. Guaranteed.

Without professional monitoring, if someone enters your home, there’s no guarantee the police will be alerted. “Self-monitoring” makes you do all the work—but what if you’re in a meeting? Or you don’t hear the phone?

With SimpliSafe’s professional monitoring, we’ll alert the authorities the moment there’s trouble, guaranteed. Our monitoring specialists are trained to stay on the phone with you to make sure you are okay and provide updates as the police arrive on scene.

THE VERGE 9/7/18

Less markup. More security.

A common misconception: the more you pay, the more you get. But the truth is you’re paying for more markup. Not more security.

You shouldn't have to pay more so we can do less. We cut out the technicians, so you get award-winning protection at fair and honest prices.
