Firewalls vs. Data Diodes

When talking about data Diodes, a question that people often ask is, “So, what’s the difference between firewalls and Data Diodes?”
We say that the two are complementary, as Data Diodes provide additional security measures for especially vulnerable network segments. Looking into more detail, however, it is clear that firewalls and Data Diodes have totally different concepts.

Also, we tend to believe OT subsystems are immune from threats because threats will only originate from the enterprise or upstream networks.
