Choose the deployment model based on a control you need.

Letro is available in three deployment models: Cloud, Dedicated, and Sovereign. Each gives you the same core platform for secure client communication, document handling, and structured workflows. What changes is the level of operational separation, infrastructure control, and residency governance.

Insights That Drive Secure Communication Forward

Forget Your Size, Define Your Preferred Control

Our pricing is set based on different data control, not on company sizes. Every Letro deployment is built for formal, secure communication. The difference is not whether you a less advanced product. The difference is how the environment is operated, isolated, and governed.

A smaller regulated firm may need Sovereign from day one. A larger organisation may choose Cloud for speed and simplicity

Choose by Requirements, Not by Size

The right deployment model depends on how much control your business needs over infrastructure, data location, operational boundaries, and external trust. A five-person firm handling sensitive matters may need Sovereign. A large institution launching a new workflow may begin in Cloud. The right choice is the one that matches your operating reality.

Letro Dedicated

is not reserved for organisations with 200 people. It is built for any firm whose regulatory obligations — or whose clients — require that no other entity's data ever touches their communications server.

Letro Sovereign

runs on your infrastructure. Your servers, your data centre, your jurisdiction. Letro has no access to your environment once deployment is complete. It is not a feature we add to an existing plan.

For clients

requiring air-gapped operation — where the communications server has no connection to the public internet — Sovereign is the only architecture that makes this possible.

FAQs

Can a small company choose Sovereign?

Yes. Sovereign is for organisations that need stronger control, not for organisations of a certain size.

Is Cloud less serious?

Cloud is a fully valid deployment model for businesses that want secure communication without private infrastructure overhead.

Why would a business choose Dedicated?

Dedicated gives a business its own environment and clearer isolation, which is often important for internal policy, customer assurance, or procurement review.

Can the right model change over time?

Yes. Deployment is a strategic choice, and the right model can evolve as requirements become stricter or more complex.
