Features and Benefits of a Dual WAN Firewall

Today, it is more important than ever to keep your company and employees connected to the Internet. Email, remote access, and research are just a few of the critical functions the Internet plays in your business today. However, when the Internet connection goes down business comes to a stand still. No one is able to work at their fullest level of productivity and your customers are waiting for that all important email from you.

What is a Dual WAN firewall?

The dual WAN firewall is a security appliance that allows you to stay connected to the Internet even if you main ISP goes offline. In order to achieve this you will need to have a second ISP connection. This can include:
  • » DSL provider
  • » Cable provider
  • » Satellite ISP provider
  • » Wireless ISP provider
When the main Internet connection goes offline the second ISP connection is switched to immediately and everyone continues to work... business as usual.
