Problems with e-mail attachments

Attachment size problem:

Most e-mail servers limit the size of attachments to less than a 50 MB (often even 5 MB or 10 MB). E-mail communication is therefore not suitable for exchange of large documents, which often exceed these size limits for attachments.

Attachment blocking problem:

The security nowadays often requires using highly restrictive policies for attachments allowed in e-mails. Such policies for example block executable files, documents containing macros and even archives containing such files.

The SOFiE application enables you to safely send and receive files, which are problematic in e-mail communication. Files can be analyzed by a SandBox (protection from zero-day threats).
