Email security your clients can see.
Deliver email security capabilities to client environments with a gateway you deploy on infrastructure you or your clients control, and licensing that's clear from the start.
What we hear from teams like yours.
Every client is different
Different mail systems, domains and tolerance for change.
Tools that are hard to hand over
Complex consoles mean every change becomes a ticket.
Licensing surprises
Per-seat pricing that shifts as clients grow.
Clients asking where their data lives
Regulated clients want an answer that isn't “someone else's cloud.”
Practical protection, clearly licensed.
Deploy per client or per gateway
Install on a Debian host per client, or run one gateway for many domains on the license that fits.

An accounting firm that wants it on-prem
Install on the client's own VM; your team administers through the console with operator accounts.
A client with dozens of domains
Enterprise licensing removes user and domain limits.
Know the boundaries.
We'd rather you hear the limits from us.
- Each deployment holds its own master key on its own host; nothing is shared through Rubix.
- Licenses are node-locked to the appliance they're activated on.
- We don't claim multi-tenant MSP management features beyond what's documented. Ask us about your setup.
- Managed hosting by Rubix is available by request only.
Managed Service Providers questions
Is there an MSP partner program or multi-tenant console?
We don't publish a multi-tenant management console. Licenses are per appliance and node-locked. Talk to us about MSP terms and how best to structure client deployments.
Can one gateway serve several client domains?
Yes, within your license: Professional covers up to 10 domains; Enterprise covers unlimited domains. Domains can have their own policy overrides.
How does licensing work for multiple appliances?
Each appliance is activated with its own node ID. An activation code can carry multiple seats; each appliance you activate uses one.
Can Rubix host it for our clients?
Managed hosting is available by request, not as a catalog plan.
