GoKawiilNot everyone feels at ease with self-defense tools that rely on physical confrontation, and I'm no exception. For many, myself included, personal safety alarms offer a straightforward alternative. These devices are especially helpful for families, whether it's a child signaling for help after getting separated in a crowded space or a parent needing a quick way to alert others in an emergency. But personal safety devices are useful for everyone, from solo joggers to commuters and hitchhikers.
In this guide, I've rounded up some of the best personal safety alarms that I and WIRED staffers have tested. We also have a guide for the Best Personal Safety Apps, as well as a guide for apps that help people with disabilities travel more easily.
Updated July 2026: I've removed discontinued products and added an FAQ section. Prices, links, and product information were also updated.
