Phoenix Contact offers license for mGuard firmware to support OPC communication

MIDDLETOWN, Pa. – A new license for Phoenix Contact’s FL mGuard security devices can protect OPC Classic applications. While traditional firewalls do not offer protection for this protocol, users of mGuard firmware version 8.1 and beyond can now upgrade to the OPC inspector license.

The OPC inspector firmware looks into the transmitted data packets, analyzing and modifying them as necessary. The OPC inspector dynamically creates firewall rules matching the ports and directions used by OPC traffic. It identifies and blocks all non-OPC traffic. It also permits the use of network address translation (NAT) procedures, such as masquerading or 1:1 NAT routing.
