A firewall is a type of network security device that is used to protect your network from unwanted traffic. The firewall monitors incoming and outgoing traffic and decides whether the traffic is accepted or blocked based on predefined rules.

Firewalls can be implemented as a hardware or software solution and can be customized according to the company's needs. They are an important part of the network security infrastructure.

How does a firewall work?

A firewall provides protection by monitoring traffic and responding to threats. It can filter traffic based on IP address, protocol type, or port number. The firewall can also determine whether the traffic comes from a known or unknown source or destination and respond accordingly.

The firewall typically operates at the following three levels: network level, transport level, and application level. It can also support special security functions such as VPN.

In summary, a firewall is an important tool to protect your network from unwanted traffic. By monitoring traffic and responding to threats, it saves time and money and enables companies to operate safely.
