We introduce a custom solution for protected private communication, suitable for groups of 2-50 persons. It is based on a server software appliance that can be either hosted by us or self-hosted by the user and a set of modified smartphones with customized LineageOS . It covers three types of communication:
- Voice and video calls.
(Conference calls are possible, but require one of the parties to have bandwidth and hardware capacity for all participants due to the end-to end encryption)
- Instant messaging with group chat, audio and video messages.
(Based on the Jabber protocol)
- Internal E-Mail
To ensure the safety of communication multiple layers of encryption are overlapped:
- Secure VPN connection to the server
(Using WireGuard or OpenVPN)
- Protocol encryption based on two way certificate exchange
- End-to-End data encryption
