VNCiom

VNCiom is the federation layer of the chat: it lets people in two different organizations message each other securely, while each organization keeps full control of its own users, data and policy.

Federation changes the trust model. In a normal chat deployment, all participants belong to the same organization and the same directory. With VNCiom, two organizations — each with its own directory, its own server and its own rules — agree to exchange messages. Nobody has to create an account in somebody else’s system, and no organization hands over its user list.

What it delivers

Cross-organization messaging without a shared tenant. Two independent deployments can talk to each other; identities stay in their own home.
Policy stays local. Each organization decides who may federate and with whom; the other side’s directory is not imported.
Sovereign data boundaries. Messages are delivered between the two organizations, not mediated by a public messaging provider.
A basis for supply chains and partnerships. A supplier, a partner or a public body can be reached over chat without inviting them into the internal workspace.

Main capabilities

Capability	What it gives you
Server-to-server federation	Messages between organizations’ own chat servers.
Home identity	Each person messages from their own organization’s account.
Domain-level trust	Federation is granted per partner organization, not per stranger.
Local retention and policy	Each side keeps its own history and rules.
Coexistence with internal chat	Federated contacts sit next to internal ones with a visible distinction.

Typical use

Two companies working on a joint project exchange updates in chat without creating guest accounts in each other’s systems.
A supplier answers questions from the procurement team in a federated conversation instead of a public messenger.
A holding company connects its subsidiaries’ separate deployments while each keeps its own directory.

How it fits the suite

VNCchat und VNCvideo is the chat application; VNCiom extends it beyond the organization’s boundary.
VNCdirectory provides the internal identities that federation exposes only as needed.
VNCchannels remains the internal record; federated chat is the conversation across the boundary.
