Encryption for serial Modbus or DNP3 

EncryptorPak is a serial encryption appliance that secures point-to-point and multi-drop links that use Modbus, DNP3, and other stream protocols. It features the advanced encryption standard (AES), hash authentication, up to 200 secure links, and two levels of encryption keys. Easy installation; no change to existing network. 

Flexible serial interface  
Mix or match any combination of RS-232, RS-422, or RS-485 (2- or 4-wire) interfaces via DB-9 or terminal block.  
Mixed mode for seamless operation  
Allows a mix of encrypted and clear traffic over a single link for segmentation or migration purposes.
