Send Files Securely

Why are we offering secure file sending services?

Email exchanged between a Princeton University email account and one managed by any organization outside of the Princeton network is insecure. The message and attachments passing between the sender's and recipient's email systems are in a form that can be read by anyone with access to the computers through which the email travels.


Email exchanged exclusively among Princeton University email accounts is afforded a higher level of security. Each message is encrypted as it travels from the sender to the University's email server and from the University's email server to the recipient. However, Princeton email users may currently forward University email to an off-campus email account potentially exposing an email and attachments to unintended parties. Your message to a Princeton email account may actually leave the campus, potentially being delivered insecurely to a non-Princeton account, e.g., GMail, Yahoo mail, etc.

 
To ensure that a file being sent to a non-Princeton email address will be transferred securely, or if you want to provide additional security for files you need to transfer to someone within Princeton, we offer several secure file sharing options.
