Cujo - Smart Internet Security Firewall with FREE SUBSCRIPTION

CUJO smart firewall protects your computers and IoT devices against malware, ransomware, viruses, and other hacking threats. Think of it as advanced antivirus for all your connected devices - from laptops to smartphones to smart TVs or gaming consoles.

CUJO acts as an internet security gateway between your connected smart devices and the internet. CUJO sends packet meta data (but, for your privacy, never full packets) to the cloud to analyze device behavior. It compares your traffic to commercial internet security threat feeds and makes sure that unauthorized IP’s do not connect to your wired and wireless home network.

CUJO network hardware firewall is blazing fast. 1GB Ethernet ensures that your network speed is unaffected by network security. CUJO connects to your WiFi router in two modes: Direct connection using DHCP mode (automatic setup for most routers), or bridge mode for networks with several routers and/or modems.

Connect With Your Router

CUJO connects to your router using an ethernet cable. It immediately begins protecting your internet devices. In CUJO app you will see all smart devices on your network. CUJO will send alert notifications when it blocks internet threats.

If you need any support, CUJO support team is available by phone, in-app video call, or email. Our team will guide you through the setup. CUJO can also send an installer to your home to provide white-glove setup service (US only).

CUJO connects with most standard routers such as Netgear, Eero, Linksys, D-Link, and TP-Link. CUJO also works with most ISP routers from Comcast, AT&T, Verizon, TWC, and others. CUJO is not compatible with Luma and does not support Google Wifi Mesh.

Business-Level Internet Security For Your Entire Network

With our homes full of connected devices, we have opened our doors to become easy targets for criminal hackers. When a criminal hacker attempts to access your smart home devices, or when you are lured to malware sites, CUJO smart internet firewall will block those cyber threats.

CUJO applies IP/URL threat intelligence, behavioral analysis using machine learning, unauthorized remote access detection, command & control detection, and other internet security methods to keep your smart home safe. When CUJO firewall appliance detects a hacking threat, it alerts all other CUJOs firewalls. Using shared intelligence, CUJO hardware firewall evolves to offer up-to-the-minute protection against malware and hacks

Protect Your Finances

Hackers use ransomware, viruses or malware to access your finances by exploiting internet security flaws in your smart devices. Your antivirus software and malware security software can only protect your laptop. CUJO internet security firewall will protect all devices connected to your WiFi router.


Safeguard Your Family

CUJO Parental Controls finally give you control over what your kids access online. Protect your children from inappropriate sites, provide internet access policies to any or all devices such as a smartphone, gaming console, tablet, or computer. With CUJO app you can control your kids’ online activity when they connect to your home WiFi router.

Ensure Privacy

A hacker can trick you into visiting a malicious phishing site to gain access to your data, hack your cameras and smart devices. Antivirus software only protects your laptop and only against a limited type of cyber threats. VPN software will encrypt your communications, but it will not prevent hackers from accessing your devices. Exposed and unsecured devices mean it's a matter of when, not if, you will be hacked. CUJO adds wireless security and hacking protection for all your connected devices.
