Your confidential conversations live in someone else's house.
With Naisho, internal chats, files, calls and meetings go through your own computer. No external provider reads or stores them.
内緒 (naisho), Japanese for “let's keep it between us”.
What changes in the office.
- 1
A computer in the office.
A computer or mini-PC that stays on, with Windows 10/11 or Linux (64-bit, x86_64), an SSD and 4-8 GB of RAM depending on how many of you there are. Whoever looks after your computers installs it in under an hour. Chat and calls need no open ports on the router; only the optional High quality video needs one or two.
- 2
An app for everyone.
Web, Android, iOS. One invite each.

You keep the tools you already use for customers and suppliers.

Questions from your IT manager
Do we need to open ports?
No. The Outpost can only be reached through Tor, a public and legal network.
Does the Outpost read the messages?
No. They are encrypted on the sender's device; the Outpost holds them for whoever is offline, without reading them.

How it works
No open door for messages: your own computer, which nobody can find on the network.
