What is a Letro Dedicated Server

A Letro Dedicated Server is your organization's own private, encrypted communication environment, running on dedicated infrastructure inside the Letro Private Cloud.

Security note: On a Dedicated Server, content is end-to-end encrypted before it's stored or routed — Letro cannot read your conversations. Only the operational information needed to run the service exists on the server, and your organization chooses which jurisdiction that server lives in.

The idea in one line

Instead of sharing a general messaging service, your company gets a dedicated, isolated Letro environment on its own infrastructure — deployed on AWS or a selected European cloud provider, in the region you choose, governed by your organization. It's built for teams whose sensitive work has outgrown ordinary messaging tools and who need to control where data lives, who has access, and whether the provider can read the content (Letro can't).

What you get

  • A dedicated private cloud. Your own isolated environment on dedicated infrastructure, deployed on AWS or a European cloud provider — not a shared, multi-tenant service.
  • Data-residency control. Choose where your environment is hosted — the EU, Switzerland, Germany, or another supported jurisdiction — to meet GDPR and sector-specific rules.
  • End-to-end encryption. Content is encrypted before it's stored or routed. Letro cannot read your encrypted conversations.
  • Access & device governance. Decide who belongs, which devices are trusted, and who can reach your most sensitive spaces.
  • Company-owned identity. Organizational identity and user governance with secure business workflows — no reliance on employees' personal phone numbers.
  • Controlled external communication. Limit, approve, or route outside contact through managed guest access, rather than through unmanaged channels.

Who it's built for

Organizations that handle confidential or regulated information, including financial services, trustees, family offices, law firms, healthcare, and other regulated professional services. See Benefits & who it's for for how these map to real needs and how Letro compares to consumer and workplace chat tools.

How it works, briefly

Under the hood, a Dedicated Server is a dedicated, end-to-end encrypted server just for your organization. Sensitive content is never stored unencrypted; only the operational information required to run the service (such as which accounts and devices exist) lives on the server. That's what lets Letro offer both a managed service and content it cannot read.

For end users, it looks and works like any other Letro sign-in — the difference is that their app connects to your organization's dedicated server. See Create your account & first sign-in.

Inside the guide:

  • What to have ready — your Dedicated Server address, your PostNumber, and your password.
  • Installing and signing in — choosing your organization's server instead of the default, then signing in with your PostNumber.
  • Backing up your data — turning on encrypted backup and saving your recovery key.
  • Adding a second device — signing in and verifying a new phone or laptop.
  • If you can't sign in — the first things to check.

Good to know

  • End users don't manage the server. As someone using Letro day to day, you simply sign in to your company's environment. Provisioning, region choice, and administration are handled by your organization — see Set up & administer your Dedicated Server.
  • Dedicated is how most regulated teams run Letro. If your company handles confidential information, a Dedicated Server is usually the deployment behind your account.
  • The encryption is the same strong end-to-end encryption Letro uses everywhere — the Dedicated Server adds ownership, residency, and governance around it. See How Letro protects your messages.
