Secure your home

The insecurity of things

Who connects to your home network? Are your devices secure, and if not, what can you do about it? Many devices are vulnerable to external access and control, which puts your privacy at risk. Home Guard helps keep you safe by identifying ways hackers can hijack your smart devices.

Intruders in
your network?

Are neighbors freeloading on your Wi-Fi and slowing you down? Home Guard regularly scans your network, mapping all connected devices, noting new ones, and storing previously detected devices in your dashboard.
