Overview

The conventional way to protect a network from attackers and threats is to use a firewall to inspect all traffic to and from the Internet. This is a very common design, which focuses on protection from the Internet, but leaves the network vulnerable to attacks from within the network itself, from connected endpoint devices and external media.
Ideally, a network would defend itself based upon the threat detected and the device that caused the problem. Enter the Allied Telesis Self-Defending Network solution. We created this solution to work with your existing firewall to instantly respond to insider threats and automatically decide the appropriate reaction for any detected attack.
The major benefit of the Self-Defending Network is immediate and accurate threat response, without any manual intervention. Actions are configurable depending on the firewall event, so that inadvertent visits to questionable webpages can be distinguished from malicious attempts to steal data.
Suspect endpoints can be automatically isolated whether they are wired or wireless, ensuring there are no weaknesses anywhere on your network. The Allied Telesis Self-Defending Network does not require any special software or agents to be installed on the endpoint. Instead of shutting down the user’s device, we control the network to restrict access until remediation can be applied. We can block a threat emanating from a data center server just as easily as one from a mobile device.
The Self-Defending Network also monitors and protects traffic moving within a corporate network without adding unacceptable latency. Our solution allows the security appliance to monitor a copy of the traffic (i.e. “one-armed”) so no latency is introduced, and threats can be blocked instantly and automatically.
