Secure Team Messaging

Private, encrypted messaging for your team

A secure, end-to-end encrypted messaging system for iPhone and Android, set up individually for each team on its own private server. Your conversations stay between your people—on infrastructure built only for you.

Introducing Red.One Encrypted Messaging: secure communication, built for privacy. Two smartphones show an encrypted team chat, with end-to-end encryption, your data under your control, and private-by-design messaging.

Built for teams that need to communicate privately

Executive protection details, family offices, leadership teams, and other groups with elevated privacy requirements need a way to talk that is not tied to personal phone numbers or shared public infrastructure.

Sealed End to End. Only your team can open it. A black envelope closed with a red Red.One wax seal, surrounded by glowing encrypted data.

End-to-end encryption

Every message, photo, voice note, and file is encrypted on the sender’s device and can only be decrypted by the people in the conversation.

Post-quantum-resistant protection

One-to-one conversations add modern post-quantum-resistant key exchange, designed to help protect against traffic being recorded today and decrypted in the future.

No phone number, email, or username

Staff do not need a phone number, email address, or username to use it, so team members are not tied to personal identifiers.

Your own private server

Each team runs on its own dedicated server, set up individually for that team—not on shared public servers.

Password-locked access

The team server is protected by a team password, so only your people can connect—even if an invite code or link is shared outside the team.

You control who is in

Your team administrator decides who joins and who is removed. When someone leaves the team, their access can be closed off.

A server that cannot read your messages

The server only relays encrypted data. It cannot read the content of your messages or files.

iPhone and Android

Works on both iPhone and Android, so mixed-device teams can communicate on one secure system.

Set up and maintained by Red.One

Red.One builds, secures, and maintains the server for your team, so your staff can focus on the work, not the technology.

Set up individually for each team

Every Red.One Secure Team Messaging deployment is configured for a single team. Your team gets its own private server, its own access password, and its own administrator controls. Nothing is shared with other Red.One clients.

Dedicated infrastructure

Messages and files are relayed through a private server set up only for your team, not through shared public servers.

Encrypted end to end

Content is encrypted on each device before it is sent. The server passes along encrypted data it cannot read.

Locked to your team

A team password is required to connect to the server, keeping outsiders off your system.

Managed for you

Red.One handles server setup, security, and ongoing maintenance.
