MetaDefender Security Gateway provides unilateral or bilateral inter-zone data transfer and streaming across the zones. The zones are referred to as BLUE (inner) and RED (outer) and are joined by a PCI cable. This cable facilitates the transfer of non-routable data between the zones. No direct network connection exists and no pertinent network information (IP address, MAC address) is exchanged.
The unilateral (USG) and bilateral (BSG) versions of MetaDefender Security Gateway are separate products. MetaDefender Unidirectional Security Gateway transfers data from the BLUE zone to the RED zone only. In addition to all unilateral transfers and streams, MetaDefender Bilateral Security Gateway adds support for bidirectional TCP.
The inner zone (BLUE) corresponds to the network in the customer site that requires protection. The outer zone (RED) is the more public-facing network of the site. Usually, the inner and outer zones are isolated from one another to protect the inner zone.
For example, a water treatment plant would have all its systems in the OT (BLUE) zone. Areas such as Plant Management, Accounting, and Engineering would be in the IT (RED) zone. MetaDefender Security Gateway would pass data in a secure manner from the OT zone to the IT zone.
