Emailing large files can be a security risk
Emailing large files creates problems for both users and IT departments. As the size of documents, images, presentations and other file attachments continues to grow, sending large files via email can quickly lead to performance problems with email servers and cause email traffic to slow. But users need to be able to share large files as part of their daily workflow in order to be productive.
To circumvent file size limits on attachments, many users turn to workarounds, including third-party file sharing services like Dropbox when emailing large files. While this simplifies big file sharing for users, it creates headaches for IT departments. Content can't be checked for data leaks or malware, and since third-party services fall outside the organization security parameters, large files are more likely at risk.
For organizations that want to know how to send a large file securely and easily, Mimecast offers Large File Send, a solution for emailing large files that meets the needs of users and IT administrators alike.

Large File Send also enables users to receive large files from contacts outside the organization, delivering a bi-directional tool for sharing data that overcomes the limitations on mailbox sizes and file attachments of infrastructure for both internal and external participants.
When emailing large files, attachments are securely uploaded from the user's mailbox to the Mimecast cloud.
