FOLLOW THE EXCHANGE1 of 6
01 Recipient
It starts in their own inbox.
The recipient receives a Greyfell-branded email from Helen, with a link to open the protected message. This is the email that actually arrived.
A familiar starting point for someone outside your organisation.
02 Recipient
One clear route to the message.
Open Secure Message takes the recipient to Greyfell’s secure page. Email verification controls access to this message; the confidential document stays in the protected exchange.
WSD handles the access checks behind the link.
03 Recipient
The document opens in their browser.
The recipient opens the engagement letter directly in the secure message. They can read it without creating a WSD account or installing an application.
The recipient works with the document. WSD handles decryption.
04 Recipient
They can check the proof themselves.
Download the evidence bundle and select it in the browser verifier. WSD checks the evidence locally against the message and protected files.
No manual hash comparison or command-line verification.
05 Recipient
Authenticity becomes something they can check.
The recipient’s browser confirms sender identity, message integrity, attachments and valid cryptographic evidence. Here is the actual successful result.
Confidence for the recipient. A verifiable record for the sender.
THE VALUE FOR BOTH SIDES
Easy to receive. Powerful to prove.
Your recipient gets a simple way to open the document—and a way to establish that the protected message and files match their cryptographic evidence.
For the recipient
Read the document, check its authenticity and reply without creating a WSD account.

WHAT WSD BRINGS TOGETHER
The complexity stays underneath.
A secure exchange needs more than an attachment: protected files, controlled access and a way to establish authenticity. WSD brings those pieces into one conversation.
