Microwall Bridge

  • Microwall Bridge

Protecting machines and equipment - without changing the IP setup

Segmenting network and isolating of sensitive network areas is one of the basic measures in virtually any IP security concept for protecting industrial environments. With the Microwall Bridge this can be done IP-transparently while the network configuration including routing of all involved components remains unchanged. Whitelist-based and using simple and intuitive filtering rules on the TCP/UDP/IP level only the explicitly desired communication between the island and the surrounding network is enabled. The protocol-transparent operation makes the Microwall Bridge especially suitable for post-segmenting of already existing network environments.
