Managed Firewall

Managed Firewall

A firewall is your corporation’s first line of defense for protecting valuable information assets. Yet expertise in this field is not always up to the challenge as demonstrated by the constant reports of corporate systems that have been successfully attacked and penetrated by unauthorized intruders. Installing, configuring, and monitoring a firewall can be more dangerous than a complete lack of one because it creates a false sense of network security.

Firewall Basics

Properly installed and configured, a firewall acts as a gatekeeper between your internal network and the Internet, monitoring network traffic and allowing only the services and access that your enterprise requires.
