Cambridge Industries Group (CIG) device on my network
Cambridge Industries Group (CIG) is a Shanghai-based manufacturer of broadband and networking equipment.
What Cambridge Industries Group (CIG) makes
CIG builds fibre optical network terminals, broadband gateways, Wi-Fi routers and optical modules, mostly for internet providers who supply them under their own name.
What the device on your network probably is
Most likely the fibre box or router your internet provider installed. Less often a provider-supplied Wi-Fi extender or mesh unit.
How to work out which device it is
Compare the MAC address with the label on your fibre box, router or extender. If it is the device at your router's IP address (often 192.168.1.1 or similar), that settles it.
Should you be worried
Nothing to worry about: this is almost always your provider's own equipment. The CIG name is the manufacturer, not the provider brand on the box.
The app finds every device on the Wi-Fi you are on, at home or in a rental, and puts the vendor next to the hostname, the services it advertises and its open ports, which together usually name the product. Where it cannot tell, it says so instead of guessing. Get RECON for iPhone — one-time purchase, no account, nothing leaves the device.
