Protocol Converter/ Multiprotocol Gateway
with enhanced IT-security

OHP’s protocol converter ensures that communication partners in our digital world understand each other securely. To this end, the ProXkon protocol converter has the most common protocols, enabling communication networks with heterogeneous participants to be set up and secure data exchange to be implemented between network participants from different manufacturers.

Integrated data processing, analyzer and router functions allow data to be pre-processed for other communication participants. Due to the continuous maintenance of the software, the central components of the IT security functions, such as VPN tunneling, encryption, authentication, etc., are state-of-the-art and can be certified in an ISMS according to ISO 27001.
