RavenFlo encrypted group chat on a phone and a laptop, between Treasury Ops colleagues.

End-to-end encrypted By default, on every message and call.

On your premises Or your private cloud, never ours.

Designed for 30,000 people Across headquarters, disaster recovery and every branch.

Your biggest decisions are being made on apps you don't own.

Approvals, deal terms, customer data, board discussions. Every day they travel through consumer messengers and foreign clouds, outside your security, your retention rules and your audit trail. Not because people are careless, but because those apps are easy.

RavenFlo makes the secure choice the easy one.

Familiar

Nothing new to learn.

Chats, groups, voice notes, photos, documents and calls work exactly the way your people expect. On Android, iPhone, Windows and Mac, from the first minute.

Message↑

RavenFlo screens for chat, files, a call, the desktop app, and a message queued offline.

Private

Readable only by the people in the conversation.

Every message, file and call is encrypted on the sender’s device and decrypted only on the recipients’ devices. Our servers, and yours, only ever see sealed envelopes.

A message is encrypted on the sender’s phone, carried through your server as a sealed envelope, and decrypted only on the recipient’s phone. Sender’s device Your server sees a sealed envelope Recipient’s device

Keys stay on devices.

Each device creates its own keys. They are not kept for us, or for your administrators, to read the chat.

Post-quantum hybrid encryption.

Protects today’s messages against tomorrow’s quantum computers, as well as the computers we have now.

Verified, open design.

Read the whitepaper. Review the architecture with our engineers.

Governed

Privacy for people. Accountability for the organisation.

Regulators and auditors still need records. RavenFlo keeps a copy of every message sealed to a compliance key that only your organisation holds, and opening it takes two authorised people, every time, with a permanent audit trail.

Your key, your HSM.

The compliance key lives in hardware you control.

Two-person approval.

Every archive access needs two authorised people.

Retention, legal hold and audit.

Built in, and written down when someone uses them.
