Your servers.
Your data. Your control.
The full platform deployed on your own infrastructure under commercial licence. Nothing leaves your estate, and you operate it with our support behind you.
Self-managed licence at a glance
- Runs in your data centre or cloud — AWS, Azure, on-premise, wherever you need
- Your data never leaves your estate, which settles most sovereignty questions outright
- Annual licence, no revenue share — your growth doesn't increase what you pay us
- Training and handover included so your team can actually run it
- Custom modules built to spec and delivered into your deployment
- Source remains Zephyr property — escrow discussed where procurement requires it
What you get out of it
Every deployment model runs the same platform. What differs is who operates it and where the data sits.
- Full operational control — you decide maintenance windows, not us
- No per-port licensing, so scaling channels doesn't trigger a renegotiation
- Your compliance posture — data residency answered by where you deploy it
- Support from the engineers who wrote the code, not a partner channel
Self-managed licence questions
Who is this for?
Operators with regulatory or contractual requirements that make hosted deployment difficult — government, financial services, or markets where data residency is legislated. Also anyone who simply prefers to own their infrastructure.
What do we need to run it?
A Linux environment with reasonable specification. We'll size it against your expected concurrent channels and CDR volume rather than quoting a generic figure, and we'll be honest if your estimate looks light.
Do we get the source code?
No. Source remains Zephyr property. You get a licensed, supported deployment you control operationally. If source escrow is a procurement requirement, raise it early and we'll discuss terms.
What happens when we need an update?
We package and you apply, at a time you choose. Nothing is pushed to your environment without your say-so.
