Cryptshare is a secure communication platform that makes it easy to exchange sensitive emails and large files with anyone—customers, partners, and suppliers—without risky workarounds or complex user accounts.

 

Built for everyday use, Cryptshare works directly inside Outlook and Microsoft 365 and in any modern browser, so users can start sending protected content in minutes.

​

At its core, Cryptshare encrypts messages and attachments in transit and at rest, then wraps them with policy-based controls such as expiry dates, download limits, and optional access codes delivered via a separate channel (e.g., SMS).

 

Recipients don’t need to register or remember passwords; they simply authenticate with the agreed method and download securely.

 

This removes the friction of portals while eliminating file size limits that plague standard email, enabling transfers of gigabyte-scale content reliably.
