Initial Situation - Attachments Overwhelm Mail Server & Compliance
Email systems rarely accept more than 50 MB mail size. However, departments need to transfer CAD models, CT image series, log archives or contract volumes with three-digit megabyte sizes.
Many competitors can only be rented from US cloud platforms as cloud products. Your data is often outside the EU; FTP servers lack traceability and end-to-end encryption.
