Talk to us about MSP terms
Tell us about your client base and we'll walk through deployment and licensing.
Simple to explain. Simple to run.
- Pick the deployment
One gateway per client, or one gateway for several client domains within your license.
- Activate per appliance
Each license is node-locked to the appliance it runs on.
- Operate with your team
Operator accounts for day-to-day work; auditors get read-only access.

Clear about what it does and doesn't.
Each deployment keeps its own key on its own host.
Every configuration change is logged automatically and exportable.
There's no published multi-tenant console, so we'll be straight about what fits your model.
Before you ask
Is there a multi-tenant MSP console?
Not one we publish. Licenses are per appliance; per-domain policy lets one gateway serve several domains. Let's talk about how you'd like to structure it.
Can Rubix host gateways for our clients?
Managed hosting is available by request only.
Can clients start free?
Yes. Community is free for one domain and one administrator, handy for a pilot.
