Sealed on arrival, sealed at rest.
Confidential delivery that never leaves the portal.
Postrider lets banks, law firms, and businesses send secure messages and documents to their customers. The content stays protected on the portal — recipients only get a notification that something is waiting for them.

How it works
1. Send securely
Write a message or upload a document for a customer. It’s protected the moment it’s sent.
2. Notify, don’t expose
The customer gets a simple email saying something is waiting — never the content itself.
3. Read on the portal
The customer signs in to read the message or download the document — safely, in one place.
Built for both sides
For businesses — onboard customers automatically: address someone by email and they’re invited to a secure account. Invite your whole team, organize by company, and keep a complete record of everything sent. Store files in an encrypted team vault, sort everything into folders, and keep client details in a private or team address book that stays encrypted — even we can’t read it.
For consumers — one trusted place to receive and read sensitive communications from the businesses you work with, plus private encrypted storage for your own files, with optional auto-deletion.
