Cryptshare.express is an on-demand service from Cryptshare for businesses that need a straightforward way to protect email communication and exchange files. Designed for companies with up to 25 employees, it helps users address security needs associated with sharing confidential business information and supporting GDPR requirements, without requiring their own IT infrastructure. Customers can send and receive secure emails and transfer files of up to 10 GB; transfers can be recalled through Outlook or the web app and remain available for up to 10 days. Communication partners do not need their own Cryptshare email accounts.

The service includes the Cryptshare Web App, an Outlook integration, and browser integrations for tools including Firefox, Chrome, Edge, Opera, and Safari. Users need an email address and a modern web browser to get started. Plans are offered as prepaid one- or two-year subscriptions, with transparent terms, no setup fee, and secure payment by credit card or direct debit. A seven-day free trial is available for organisations.
