In critical sectors like energy supply, transportation, defense, and industrial manufacturing, protecting IT/OT networks from cyberattacks is essential, especially in applications demanding Safety Integrity Levels (SIL) 3 and 4. Implementing an air gap between OT and IT environments strengthens security by physically separating operational technology systems from external IT networks, significantly reducing the risk of cyber threats.

To enable operators to transmit data, such as sensor information, from OT networks to IT networks while maintaining the required air gap, a robust solution is necessary to securely bridge both environments.
