They support privacy preservation, provide parental controls, safeguard IoT devices, and aid in thwarting possible attacks.

What is the main difference between hardware firewall and software firewall?

A software firewall is installed on a different computer, but a hardware firewall operates on its own physical device. This is the primary distinction between the two types of firewalls.
