Write an encrypted message…
The problem
Encryption alone isn't control.
WhatsApp and Signal encrypt your messages, and that's good. But your organisation still depends on a company it doesn't control, in a country it didn't choose.
- Someone else runs the serversYour accounts, contacts and activity sit with an outside company.
- Someone else makes the rulesThey can change terms, suspend accounts or shut down a service at any time.
- Foreign laws applyYour data is governed by the laws where that company operates, not yours.
- Tied to personal phone numbersStaff must share a phone number, and anyone with the app can try to contact them.
What Salus gives you
Everything your team needs to talk safely.
The same ease as the apps people already use, with the security and ownership an organisation needs.
Your server, your data
Salus runs on your own server, in your country or your data centre. You decide where your information lives.
No phone number needed
People sign in with an account you give them, not a personal phone number that can be looked up or shared.
Only people you approve
No public sign-up. Your administrator creates every account and can remove access instantly.
Secure voice & video
One-to-one and group calls, encrypted and routed through your own infrastructure.
Works everywhere
Apps for iPhone and Android, plus a web app for computers. Messages stay in sync across devices.
How it works
Up and running in three steps.
No technical knowledge needed for your staff. If they can use WhatsApp, they can use Salus.
We set up your private server
Your own Salus server is installed where you want it: our secure hosting, your cloud, or your own premises.
Your admin invites your people
Accounts are created only for the people you choose, from a simple web admin console.
Your team chats and calls
Staff install the app, sign in to your server, and start talking. Encryption is on automatically.
Locked on your phone
Unreadable on the way and on the server
Unlocked only by the recipient

WhatsApp and Signal are trademarks of their respective owners. Comparison based on their standard consumer apps.
Built on Matrix
An open standard trusted by governments.
Salus is built on Matrix, an open, decentralised standard for secure communication. No single company owns it, so you are never locked in.
Open and independent
Matrix is a public standard anyone can inspect and build on, with no single company in charge.
Decentralised
Every organisation runs its own server. There is no central company holding everyone's data.
Connect when you choose
Stay fully private, or securely connect with trusted partner organisations later.
Matrix is used by public institutions across Europe, including:
French government
German armed forces
German public administration
Luxembourg government
Who it's for
For organisations that can't afford a leak.
Government & public bodies
Keep official communication on infrastructure you own.
Security & defence
Closed, controlled networks for sensitive operations.
NGOs & journalists
Protect sources, staff and partners in the field.
Businesses
Keep confidential deals and client data in-house.
FAQ
Common questions.
Is Salus as easy to use as WhatsApp?
Yes. People install an app, sign in, and chat, send files or call, just like they already do. The security works in the background.
Can the people running the server read our messages?
No. Messages are encrypted on the sender's device and can only be unlocked by the people in the conversation. The server stores them in scrambled form. Like any messaging service, the server does know which accounts exist and when they are active, which is why it matters that you control it.
Where is our data stored?
Wherever you choose: in your own country, your own data centre, or a trusted cloud provider. This demonstration server is hosted in Germany.
What happens if someone loses their phone?
Your administrator can sign the lost device out immediately. The user signs in on a new device and uses their personal recovery key to restore their encrypted message history.
Can we talk to other organisations?
By default, your Salus server is a closed network. If you want to, it can be securely connected to specific trusted partners that also use Matrix, and to nobody else.
Is it open source?
Salus is built on the Matrix open standard and on open-source software that is publicly available for independent security review.
Your conversations. Your servers. Your rules.
Secure communication shouldn't depend on someone else's company.
