Enterprise Software Firewalls

A software based enterprise firewall is a software package that gets installed on top of an operating system and manages a security policy for an entire enterprise. This is typically installed as a gateway between the Internet and the Enterprise network, but can also be deployed inside the network for internal compartmentalization.  Many come with Management software components to help manage multiple devices in the network.
