Do you want to transfer a large file? You probably attach the file to an email. If the file size is larger than a few dozen MBs, you receive a notification and the mailbox or mail server rejects the file. To transfer the large file anyway, you use a USB stick, an online service, a courier, a DVD, or complex SFTP servers. However, these means are time-consuming, some are expensive, and all are difficult to really secure. ZIVVER makes transferring large files secure and incredibly easy.
