Safe browsing the internet has become a security concern for everyone of late. Hackers may attempt to access your personal finances if they identify security flaws in the connected devices. They may thus tamper with hack your smartphones, plant malicious malware in net-enabled devices, and alter your Wi-Fi router. Most homes and small offices depend rely on a Wi-Fi router firewalls to keep their connection secure. This smart internet security firewall is designed with small offices and home internet connections in mind. It will keep your business and home connection secure from cyber threats so that you can keep information secure and private online. In this article, we will give you everything you need to know about CUJO Smart internet security firewall.
Why choose the Cujo Smart Internet Security Firewall
Upon CUJO cloud’s service detecting a suspicious activity or threat on a specific network, the cloud service directs the firewall to create a rule for blocking the traffic. In addition to the blocking, cloud sends a mobile app notification of the blocked traffic to the user. In case the user wants to exempt the blocked traffic, he/she does it via the CUJO app.
CUJO smart internet security firewall has an interesting shape for any network device. This firewall has an egg-shaped device with a flat top. On its backside is an AC power port and 10/100/1000 Ethernet port. The device also has 1.2 GHz 64 bit MIPS Cavium Octeon Core processor that has two Gigabit Ethernet ports and a RAM of 1 GB.
To detect security threats, cloud runs behavioral analysis engine. Although CUJO does not use deep packet inspection, it analyses traffic in order to detect threats; a similar mechanism to that of Intrusion Prevention System (IPS). This firewall device protects and detects threats and has the capacity to determine if a device on your network is compromised or is participating in a botnet.
CUJO Smart Internet Security Firewall receives and forwards from your Wi-Fi router via the 10.0.0/24 network. It communicates to your end devices via the 192.168.0.0/24 network. This happens through the same physical interface. The CUJO is seen as the default gateway by your end devices. To communicate on two different network connections that use the same physical interface, the device utilizes two different IP addresses and MAC addresses on one physical interface. The pair of two half circle eyes on the front indicates status. During normal operations, you should only light the upper half of the eyes. If you see both eyes on, then that denotes a detection of a threat.
On the downside, CUJO only looks at packet data. It is, therefore, unable to block phishing emails unless they come from a known IP address or domain. It also unable to detect downloaded files and email attachments that contain a virus. This calls for regular update malware and virus protection so as to protect all the smart devices that run it.
See the Pros & Cons
The DHCP set up mode can be simplified connecting a single Ethernet cable and making a few minor changes. In addition, all the DHCP devices that are enabled communicates automatically through the CUJO, and are protected by CUJO too. Also, the least amount of network equipment is required. Other advantages of this device include:
- Behavioral analysis of all devices
- Safe and Smart browsing
- Auto-device identification
- Recognizing device by brand, type, and model
- User-friendly devices
- Encrypted network analysis devoid deep packet inspection
- Protection from remote access, DDos
- Access control by the device
- Parental controls: URL/IP filters based on categories, time limits, schedules per profile and per device, App, shopping, adult, service and social media filters.
No great device is devoid of disadvantages. CUJO is now performing Network Address Translation (NAT) for the direct setup mode. So, if your network will now be double NATed since your router will be performing NAT. However, this shouldn’t be a big deal for most traffic. Nevertheless, with gaming, VoIP and other traffic that are connection sensitive, you might experience some problems.
Secondly, with the DHCP mode, all your network will first be going to your routers built-in switch, then to the CUJO, and back to your Wi-Fi router. This may reduce the overall throughput of your network. Thirdly cons of the Direct Mode is that it will stop the working of all devices with static IP on your computer. If you are using a VPN on your Wi-Fi router to remotely access network, the VPN will cease to work.
However, you can re-enable all statically addressed devices by configuring them for DHCP. You can also give them a static IP address on the 192.168.0.0/24 subnet. Finally, the con of the Bridge Mode is that you will need an extra network equipment. You also have to hook it up correctly as well as configure it well. With this mode, you will require two routers. The first router will be your connection to the net. Notably, any device connected to the first Wi-Fi router will bypass the CUJO Smart Firewall. Also, you will need to disable the Wi-Fi on the first router. The other router will provide Ethernet ports and Wi-Fi to the devices downstream of the CUJO device. DHCP should be disabled and the Wi-Fi enabled on the later Wi-Fi router.
Hardware and Set-up Requirements
CUJO Smart Internet Security firewall has three installation modes namely: Direct/DHCP, Direct/Automatic, and Bridge mode. In places with large networks, the CUJO firewall is normally installed in front of your network. This enables it to see all the traffic coming in and going out of your network. In-home network connections where only a single network device exists, a Wi-Fi router is normally connected to the internet. However, this may at the time be challenging. The CUJO Smart Firewall usually does not directly connect to the internet; it typically needs a router in front of it.
The first mode is the Director Automatic Mode is purposely designed to automatically configure your Wi-Fi router. All you will need to do is connect the firewall device to your router. However, the direct mode only works best with routers. For instance, it does not work well with Linksys LRT224. Below is a sample of a direct mode connection.
The second mode is the DHCP/ Direct needs few manual steps on the end user’s part. Connect the firewall device with a single Ethernet cable; this should be at the Ethernet port on the bottom; to a LAN on your router. The connection should look like the diagram below.
The third mode is the Bridge Mode. Ensure your CUJO Smart Internet Firewall sits between the Wi-Fi router and other networks devices such as Ethernet switch or a second router. Connect the bottom Ethernet port to the first Wi-Fi router. Then, connect the top Ethernet port of the CUJO Smart Internet Firewall to a LAN port on the other Wi-Fi router. The connection should look like the diagram below.
Protecting your smart devices from dangerous malware has never been this good. We have brought you one of the best net security firewalls. CUJO Smart Internet Firewall is slowing upload throughput. This is a point worth a mention. Nevertheless, for users whose ISP connection is above 250 Mbps, and are concerned about uploads, this shouldn’t worry you. CUJO Smart firewall will serve in bridge mode. CUJO is planning to add parental control feature on the firewall device. So, why not keep your browsing secure with CUJO smart internet security firewall? Make your purchase, enjoy the support of our experts, and stay secure online.
