Please say hello to us on Facebook, Twitter, and Instagram @cujounited. Follow us there to get great security tips and inspirations. Also, be sure to catch up on our blog posts where we provide important connected home security information.

We do see your IP, and is anonymized. Messages come in via push notification on your mobile device.

Do you log? Will you share with 3rd parties? Could you be required to divulge the information? We collect metadata based on destination IP addresses. We log that the communication of your CUJO device is functioning with our cloud. We will NOT share data with 3rd parties. If legally obliged, we can divulge, but the derived data may not be of much use.

We cannot see encrypted data from banks, social media, etc. We do analyze metadata in order to ensure the safety of webpages visited. The information is encrypted and anonymized. The exact behavioral data of users on your network NEVER leaves your CUJO device and it is not stored.

A VPN device secures the information you are sending to your destination. It does not keep you safe from criminals penetrating your network. Though we have a VPN feature in our product roadmap, we are focusing on the larger issue of home hacking. We do that in several ways: behavioral analysis of your device payloads, malware and virus scanning DNS, and packet inspection.

Any device can be hacked. It is a matter of how much effort and resources one would spend to do it. Being a security company we naturally focus much of our attention to prevent that from happening. We encrypt our connections. And we secured our hardware to be very difficult to penetrate. If it were to happen, criminals would not find much information since we do not store credit card data ourselves and we aggregate only limited packet information in the cloud.

We see CUJO as a very important, hopefully most important, layer of your Internet security. That said, no single solution could protect you against 100% of attacks. For example, modern Antivirus solutions are said to be effective in less than half of attacks. We believe CUJO will be much more effective because it inspects attacks at the gateway level. However, you should keep your current software security and, most importantly, stay vigilant.

CUJO does not scan what is on your PC, but rather looks at traffic coming to and leaving from your PC and other devices. Security needs to be multi-layered so it is absolutely important for you to have a good Antivirus software on your desktops and laptops.

We used to have 1 or 2 computers in our homes. Now our home is full of connected devices – from tablets to thermostats – that don’t have proper security installed. Virtual criminals are exploiting our networks to steal data, destroy devices, and monitor us at home. This has led to countless incidents that have affected people both virtually and physically. CUJO acts as a shield for your entire home network, adapting continuously to keep you safe.
