The new Modbus Inspector license for mGuard security routers from Phoenix Contact is here, making Modbus/TCP communication between machines even more secure.

When the license is installed on class 4000 security routers, the Modbus/TCP communication rules can be set with a very fine degree of granularity. With this Deep Package Inspection module, access rights can be set not only at the IP address and port level, but also for the function codes and registers used within the Modbus protocol. Modbus Inspector supports the defense-in-depth concept as defined under ISA-99 or IEC 62443 and increases the security of machines and systems that communicate using Modbus/TCP.
