Confidentiality
Encryption and controlled recipient access help keep sensitive information private and limit who can read it.
Businesses already have ways to send messages and files securely. The missing layer is proof. WSD combines secure communication with cryptographic provenance, creating independently verifiable evidence of origin and integrity.
Traditional communication systems answer: Can this information be sent securely?
WSD also asks: Can we prove where it came from and that it is unchanged?
Screenshots, email headers, audit logs and provider records can all be useful. But they can leave organisations dependent on a system or service provider explaining what happened. WSD was designed to attach cryptographic evidence to the protected communication itself.

Cryptographic evidence helps establish origin and integrity, so protected content can be checked rather than simply accepted.
WSD brings both together in one communication platform.
Use WSD as a hosted service without running your own server or cloud environment. Straightforward subscription plans let organisations start with the team they have and add users as they grow.
View SaaS plans →When authenticity matters, a defensible record is more useful than another assertion.
Hosted WSD combines client-side encryption, controlled recipient access, organisational separation and cryptographic provenance. These layers protect access to sensitive information while creating evidence about its source and integrity.
The architecture supports secure communication without requiring customers to configure their own infrastructure.
Read the security architecture →WSD is built for teams exchanging sensitive information internally and with outside parties.
Most organisations can use WSD as hosted SaaS. For those requiring dedicated infrastructure, customer-specific encryption architecture or greater deployment control, WSD also offers Private Deployment.
To give organisations more than a secure delivery channel—to give them cryptographic evidence they can retain and independently verify.
Move from “trust that this is genuine” to “prove that this is genuine.”WSD combines secure communication with cryptographic provenance and independently verifiable evidence.
