Firewall, What Is It?

What is it?

A firewall is a device that secures the network, restricting traffic to the internet and to the local network. It works by blocking or allowing access according to predefined rules. Its operation helps prevent malicious actions and stop any user from performing unauthorized actions.

How Firewalls work

Firewalls can be seen as barriers, funneling traffic so that each piece of information passing through can be analyzed. This way, it decides what’s considered safe or dangerous. The main goal of a firewall is to protect devices connected to the local network from threats present on the internet (Ransomware, Spyware, Viruses, and Botnets).

Unprotected networks are vulnerable to malicious actors and can expose private information. Firewall tools are able to act proactively, inspecting all network access, thus protecting the network against cybercriminals.
