Cujo’s Firewall Protects Connected Home’s Smart Devices

The cybersecurity battle is currently shifting from businesses to homes because homes have an increasing number of Internet-connected devices that don’t have the security protection that office networks have.

Consequently all the billions of connected devices are in danger of exposing users’ private data like user names, passwords and account numbers to cybercriminals and hackers – whether kids down the street or someone in Asia – can cause a great deal of damage and monitor eve-ry user’s activities.

 

cujo-boxCujo box: looks nothing like dog from eponymously-titled movie

 

Cujo is a simple yet powerful solution to keep homes safer by bringing business-level security to guard the home network.

It’s housed in a small cylinder-shaped box with a smile that is a smart firewall to keep home networks safe from cyber-attacks and hackers. It promises to protect “all of your wired and wireless Internet connected devices.”

Cujo CEO Einaras Gravrock said Cujo should be thought of as “an immunity system for your network.” The product, he said, brings enterprise-level security to the home network, helping protect against cyber-attacks the home’s vulnerable network and its connected devices – from PCs to smart lightbulbs to TVs to thermostats to baby monitors to smartphones.

The Cujo box looks nothing like the mad dog in the Stephen King novel and movie with the same name. It’s a small plastic cylinder-shaped unit with “eyes” that light up and which plugs into the home’s modem or router. An app shows viewers everything on their network. It continuously monitors all the devices connected to the home’s network and looks for suspicious file transfers or communications with distant IP addresses.

 

 Cujo Continuously Analyzes Network Traffic in Real Time

Cujo continuously analyzes in real time the traffic on a network. It sends statistics on that data, but not the data, to the cloud for further analysis. To protect privacy and improve performance it does not send the contents to the cloud. If it detects a threat or even suspects a threat, it immediately tells the cloud what it has blocked, which results in the user getting a notification via Cujo’s mobile app on a smartphone or tablet. Users can manually override any of Cujo’s automatic blocks.

Cujo cites these statistics when justifying the purchase of its product:
– 55% of cyberattacks are unnoticed by commercial antivirus software, according to The Guardian
– 70% of connected devices are vulnerable to security threats, according to HP
– 75% is the success rate for home hackers getting into devices
– 90% of connected devices store personal information.

If the user goes to a bad site or if something bad comes to it, such as someone trying to access the user’s camera, it blocks the bad behavior and sends the user a notification. A typical warning is “We blocked an unauthorized attempt to access device ‘IP camera’ from [IP number].”

Gravrock says that in a connected home, someone hacking into a smart lightbulb can access to other devices such as cameras and PCs where they copy files or …
