What is a Firewall and How Does It Protect You?

A firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies.

At its most basic, a firewall is essentially the barrier that sits between a private internal network and the public Internet.

There are different types of firewalls, including packet filtering, stateful inspection, and next-generation firewalls (NGFW).

Implementing a strong firewall strategy is crucial for protecting your data from external threats and unauthorized access.
