What is a Firewall?

A Firewall is your first line of defence for your device against attacks from the internet. These threats take many forms from links in emails which is a virus to people hacking your device with a Trojan and gaining all your personal details.

Firewalls work in the background, you won’t even notice they are there but they are the main part of any devices defence. They work by following a set of rules which include authentications certificates and logins to prevent hackers and viruses getting into a device or network, they also scan data coming and going from the device. Thus only data and people you allow are granted access, everything else is blocked.

A good combination is a Firewall with a VPN service, this encrypts the data as it leaves the device and protects it until it reaches its destination. Making a fully secured device and connections.
