CUJO is a smart firewall for the connected home, designed to bring business-level security to the home network. Using machine learning, CUJO safeguards ALL smart devices connected to your wireless router against web threats. It detects and blocks malicious sites, viruses, and hacks, working like an antivirus software for your entire network.
I was very excited when Best Buy sent me a CUJO for review. My home is full of smart devices with WiFi capability, including smartphones, tablets, laptops, TV, thermostat and security cameras. I was seriously in need of help in the online safety department when CUJO arrived in this cute little box. Before starting to use the device, I was already impressed by its compact size and sleek design. It's lightweight too, easy to handle with one hand. My CUJO box comes with a 3-feet Ethernet cable, an AC Power adapter, a sticker, and best of all, FREE lifetime subscription with automatic software updates. Unlike any antivirus software I've purchased before, there is no need to pay any additional fees to keep my firewall protection up to date.
My kids think CUJO is super cool because it has a face with light-up eyes indicating its working status. When it's not properly connected, it will have an unhappy or warning face as shown in the picture above. The face will turn to a smiley one when things are all set. Both the upward and downward curves will be present when CUJO is working hard to get things right.
It was amazingly easy to set things up with CUJO. It took me less than 5 minutes to get the device up and running. Just plug in the adapter and cable, install the CUJO app on my phone and follow the prompts to complete installation and registration. As our router requires some special adjustment during installation, I received a call from a CUJO customer service representative guiding me through the process. This was the first time ever that tech support was being offered without me having to ask for it. Very impressive indeed!
