Your home is smart, and therefore vulnerable

From smart TVs, smart thermostats, cameras, and lights to smart kitchen appliances, your home is smarter than you think. But there’s a catch. Every internet connected device is vulnerable to external cyberthreats.

Home Guard scans your home Wi-Fi network to detect every connected device including laptops, smartphones, routers, smart TVs, IoT appliances and more.

The app displays vital information: device category, IP address, MAC address, device name, model, vendor, then performs a vulnerability check for each device. Home Guard helps keep uninvited guests where they belong: out of your smart home.

Keep your smart home secure and hackers frustrated

Who’s on your Wi-Fi network?

Are neighbors accessing your Wi-Fi? Home Guard displays all your connected devices, detects new ones, and stores the list in your dashboard, so you always know what’s happening.

Is your smart TV spying on you?

Your smart devices may do more than what you expect. Home Guard scans all detected devices for security flaws, notably open ports, which can be used to spy on you.

Is your Wi-Fi speed up to speed?

Your favorite TV series is buffering right during the season finale? Home Guard tests your Wi-Fi speed, checks your download and upload speeds, and ping latency.
