INTRODUCTION

• Most home networks are particularly vulnerable to
  network security threats and depend on a Wi-Fi
  router's firewall to secure our network.
• CUJO is a smart firewall that keeps your
  connected home and business safe from cyber
  threats so that you can stay secure and private
  online.
• The Cujo is a small plastic stump with light-up
  eyes that stands in adorable contrast to its mad
  dog name and home security mission statement.

WHY CUJO?

• Your home is your sanctuary (safety from danger).
• That's where we experience our most private
  moments, safeguard our most precious files, and
  experience peace of mind. Until now.
• With our homes full of connected devices we've
  become easy targets for criminal hackers.
• You read it in the news every day baby monitors,
  smart TVs, tablets - all hacked. 

5
How does cujo work?

• CUJO acts as a gateway between your devices and
  for your connection to the Internet. We
  inspect packets of data coming and leaving your
  network and block threats before they can reach
  the target or do damage. We analyze behavior and
  secure all devices connected to your network.
  This is critical because newly connected devices
  don't have pre-installed security.
• Unlike traditional solutions, CUJO adapts and
  reacts when your home is attacked and does not
  rely just on libraries of known malware issues.
  We analyze a humongous amount of behavioral data
  in our cloud and push learnings from one home to
  all CUJO protected homes.

CUJO SETUP

• Step 1 Download the App Before you proceed to
  set up CUJO as a security device for your
  network, please download the CUJO app for your
  phone or tablet. All configurations, controls,
  and notifications are handled using the CUJO app.
  You can download the app from the App Store or
  Google Play.
• Step 2 Activate Make sure your phone is
  connected to the same network as your CUJO and
  proceed with activation process on the app.
• CUJO's two installation modes are
• Direct/DHCP mode
• DHCP mode
• Standby mode
• Bridge mode

7
Direct/DHCP mode

• Direct/DHCP mode is designed to automatically
  configure your router, so that all you have to do
  is connect the CUJO device to your router.

8

• 1. DHCP mode.
• In this mode, CUJO will be running the DHCP
  server, but it requires disabling the DHCP server
  on your router. The CUJO app will help you change
  the DHCP settings automatically.
• 2. Standby mode.
• In this mode, CUJO is just another device
  connected to your router, it does not protect
  your network.

9
BRIDGE mode

• In this mode, CUJO sits between your router and
  another network device such as a second router or
  Ethernet switch. In this scenario, the bottom
  Ethernet port on the CUJO is connected to your
  first router, and the top Ethernet port on the
  CUJO is connected to a LAN port on the second
  router or to a port on your Ethernet switch.

CUJO EYE STATUS

• What do the CUJO eyes mean?
• When CUJOs eyes are round, it means that it is
  filtering something.
• CUJOs eyes appear to be smiling when
  everything is good it is connected properly.
• When CUJOs eyes appear to be sad, means it is
  offline or disconnected.

11
CUJO SECURITY

• CUJO is a smart home security device that
  protects the connected home from the latest and
  most-sophisticated virtual intrusions such as
  malware, viruses and hacking techniques. CUJO
  uses self-learning technology to keep watch over
  computers, smart phones, baby monitors, TVs and
  other connected devices by constantly updating
  itself to block new threats. Created by online
  security experts with extensive experience
  fortifying software and hardware against virtual
  threats, the company is situated to transform the
  face of cybersecurity.

PROS of cujo

• Installation is simplified by just connecting a
  single Ethernet cable and making a few small
  changes.
• All DHCP enabled devices will automatically
  communicate through the CUJO and be protected by
  the CUJO.
• It requires the least amount of network equipment.

15
CONS OF CUJO

•  CUJO is also performing Network Address
  Translation (NAT). This means your network is now
  double-NATed, since your router already is
  performing NAT. It can cause problems with VoIP,
  gaming, and other connection-sensitive traffic. 
• All traffic on your network is going first to
  your router's built-in switch, then to the CUJO,
  and then from CUJO back to your router, which may
  reduce overall network throughput.

16
CONclusion

• Laptops, tablets, and smartphones offer good
  firewall protection already, but if you have IoT
  devices connected to your home or office network,
  then CUJO will help you keep protected. In
  particular, if you have webcams or baby monitors
  in use, then I would highly recommend installing
  a smart firewall like CUJO to stop hackers
  gaining access and invading your privacy.
• A smart firewall may not yet be an essential
  item for the home, it will be in a couple of
  years and it is best to get protected early to
  avoid having to deal with the consequences of a
  breach and block down after the fact.
