The benefits of a firewall:

• Firewalls protect your systems by monitoring and analysing network traffic and applying pre-set rules and filters. You can manage your degrees of security based on what you see flowing in and out of your firewall if you have a well-trained IT team.
• The ability to restrict your system's access points and thwart virus attacks is one of the most evident benefits of firewalls. Depending on the type of virus, the cost of damage from a virus attack on your systems could be immeasurable.
• Firewalls have grown even more critical as a result of the surge in data theft and criminals holding systems hostage, as they prevent hackers from obtaining unauthorised access to your data, emails, systems, and more. A firewall can either entirely block a hacker or persuade them to choose a less difficult target.
