Hanssak

Hanssak makes software that controls and secures the transfer of data between separate, isolated computer networks, a capability used by government agencies, defence organisations, and enterprises that need to keep sensitive information from leaking across network boundaries.

Its customers span the public and private sectors, wherever strict separation of internal and external networks is required. Listed on KOSDAQ, Korea's tech-focused small-cap board, the company has expanded into cloud development and artificial-intelligence research to broaden its product range.
