Dualog

Dualog provides the communication software that moves email and files between ship and shore over expensive, intermittent links. Fleet IT teams use it to control what gets sent, compress and queue traffic, and keep a managed mail path when the vessel is not on a normal office network.

It is connectivity and messaging infrastructure, not a chartering inbox. Sedna organizes the commercial conversation; Dualog gets the bytes off the ship. Operators who run their own mail policy, rather than a cloud desk product, are the usual buyers.
