Kiteworks secure file transfer allows you to securely send files with high-risk, confidential data (Level 4), internally and externally. Kiteworks is only recommended for Harvard Google Workspace users who don’t have access to a Microsoft 365 email account or anyone who needs to send attachments that are greater than 150 MB. (Microsoft 365 users should instead use Outlook's message encryption feature for securely sending confidential files with low- to high-risk data.)
