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.

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.
