Why You Need CUJO

Traditionally, PC security software, like antivirus or antimalware, is designed to only protect you the device it’s installed on. With so many connected devices in your home, you and your family’s personal lives are now on display through the networked home gadgets you have. Once connected to your router, CUJO smart firewall protects your entire home from nosy and unwanted intrusions.

Traditional Approach

Anti-virus and anti-malware software that you have on your PC mostly fails to protect you against hacks. Virtual criminals penetrate your network using vulnerabilities found in your router and your connected devices. Once they are in the network, traditional security software is mostly incapable to keep your information secure. One rogue device exposes your entire network, including the PC that has traditional security software installed.

Our Approach

CUJO creates a guarded gateway between your devices and their connection to the Internet. We analyze packets for malicious intent right there on the CUJO whether it’s coming in from the Internet, going out to the Internet, or making moves across your network. CUJO applies IP/DNS Threat Intelligence, Behavioral Analysis using machine learning, Unauthorized Remote Access detection, Command & Control detection, and other security methods. When we catch something we send packet statistics (but not full packets) to the Cujo Cloud to analyze device behavior and make sure every other CUJO is aware of this kind of attack. We guard every single connected device on your network, not just your PC. Unlike traditional solutions, CUJO keeps improving all the time to protect your home. Contact us at evg@getcujo.com if you would like to get a more detailed technical overview.
