Safe islands with Microwall

Use micro-segmentation to protect vulnerable devices in the network


Safe islands model

The Microwall separates especially sensitive or obsolete systems from the surrounding network in the form of their own network segments. These secure islands are thus protected from undesired access.

Yet they still remain connected to the network: The Microwall monitors communication with the island based on individually configured rules – only explicitly specified connections are allowed.

Background information: Firewalls, segmentation and islandization
