We run Rhema on servers your organization controls.
Rhema is a private app for messages and calls. SiliconBlast installs it in your private cloud or your own data centre and keeps it running. Your conversations and files stay on your machines, and your people use the same Rhema apps on their phones and computers.

Who we set it up for
We set up the same Rhema for a small organization or a whole government department.
Small organizations
This suits churches, schools, clinics and firms that want their own messaging. One small server in a cloud account you own is enough.
- Runs on a single virtual machine
- People sign in with Google, Microsoft or Apple
- We look after updates and backups
Enterprises
Rhema runs inside your own cloud, with the sign-in your company already uses.
- AWS, Azure, Google Cloud or your private cloud region
- Sign-in through Microsoft Entra ID, Okta or Google Workspace
- Files, calls and backups on infrastructure you own
Government
Your messages and calls stay inside your jurisdiction.
- On-premise, or in a sovereign cloud in your country
- Runs inside isolated networks
- You hold every server and every copy of the data
What SiliconBlast does for you
You don't need a team to run servers. We install Rhema, keep it up to date and watch it, while the servers and the data stay yours.
Installation
We set up Rhema, its storage and its calls server where you want them.
Updates
New versions are tested first, then rolled out at a time you agree.
Monitoring and backups
We watch the servers and back them up to storage you own.
Support
Your administrators have a direct line to the people who build Rhema.
Encryption works the same on your servers.
Messages, files and calls are encrypted on each person's device before they reach the server. Whoever runs the server can see who talks to whom and when. It cannot read what they said. The security page explains how this works.
- Keys live on people's devices
- SiliconBlast cannot read your messages
- Your administrators control accounts and devices
