The Fortinet Internal Segmentation Firewall (ISFW) Solution

With advanced threats growing rapidly in number and sophistication, perimeter security is no longer enough to keep your sensitive information safe. Once a threat gains entry, it can spread and eventually extract the valuable assets it was sent to retrieve.

You can dramatically improve your security by adding FortiGate Internal Network Segmentation Firewalls to your network to prevent the proliferation of threats once they get inside. ISFWs provide network segmentation inside the perimeter. They may sit in front of specific servers that contain valuable intellectual property or a set of user devices or web applications sitting in the cloud.
