What it means to see this device on your network
Knowing the manufacturer helps identify what is connected to your Wi-Fi or company network. A Juniper Networks MAC you don't recognize could be a legitimate device (a phone, a TV, a camera) — or one that shouldn't be there. Juniper Networks has 213 MAC prefixes registered with the IEEE (see others under "Read also").
