Completely isolate the PROFINET network from the outside world or implement security measures?

[Webinar_Question]

It seems simpler to totally isolate your PROFINET network from external surroundings rather than implementing these complex security measures.

It seems simpler to totally isolate your PROFINET network from external surroundings rather than implementing these complex security measures.

In an ideal world, security mechanisms would be unnecessary. However, due to developments such as IIoT and IT/OT convergence, the number of devices in factories is increasing, making it difficult to maintain entirely isolated PROFINET networks in all scenarios. This growth facilitates emerging use cases like predictive maintenance and production insights. Importantly, the security mechanisms in place are designed to be transparent to customers.
