How to transfer large file to multiple user without using FTP SERVER.

Hi reddit, So I need to transfer a large file size like 55GB (for work from home) And I tried using ftp but in my country ISPs have limit on FTP download. So i was looking for a way to transfer this huge file to multiple users but the data has sensitive information that I don't want other people to get ther hand on.

Is there any torrent service which is secure for sensitive files. Or any other recommendations
