Dorbar
Sovereign communication. Two levels of trust, by design.
Dorbar is a secure messaging platform built for organizations that cannot place their communications on foreign infrastructure. It is deployed on infrastructure the customer controls and is designed around a simple principle: the organization decides exactly how much the server is allowed to see.
The two-class room model
Official rooms
Server-trusted spaces for day-to-day organizational communication, with the auditability and administration that institutions require.
Sealed rooms
Server-blind spaces protected by end-to-end encryption using the Messaging Layer Security protocol (RFC 9420) with post-quantum hybrid key exchange (X-Wing). The server relays messages it cannot read.
Design principles
Dorbar is engineered for sovereignty: customer-controlled deployment, standards-based cryptography, and an interface designed for institutional use, with full Bengali language support.
