SecureShare Discontinuation and ProofPoint Transition of Services

In this article:

Earlier this year CaTS was notified that ProofPoint’s SecureShare, our current secure file-sharing service, is being discontinued this Summer. With the elimination of SecureShare, ProofPoint’s service offerings were no longer as attractive.  As a result, we are migrating away from ProofPoint products in favor of software already in our portfolio.

This migration will consist of several modifications to email processing and the transition to a Microsoft 365-based file-sharing portal. The impact on email processing and file sharing will be minimal.

SharePoint Secure File Share to Replace ProofPoint SecureShare

With the elimination of ProofPoint SecureShare, Wright State members will now be able to utilize SharePoint's Secure File Share to share sensitive documents with others, both inside and outside of the university. 

What is Secure File Share?

Secure File Share is a secure SharePoint site that allows you to securely share files with other people, both inside and outside the university. The files are stored for a temporary amount of time (typically 30 days) and are then deleted from the system. Files are encrypted while they are stored on SharePoint, and also during transfer.  

You can access Secure File Share at

Who can use Secure File Share?

At this time, all individual Wright State employees can utilize the new Secure File Share service. You can also request a Library be set up for a Microsoft Group by submitting the CaTS Online Communities request.

When will ProofPoint SecureShare go away?

ProofPoint SecueShare will be officially replaced with SharePoint's Secure File Share on June 20th, 2024. CaTS strongly recommends downloading any files currently stored in SecureShare by June 15th, 2024. Any files stored in SecureShare will be deleted once this service is discontinued on June 20th. 

When is it Appropriate to use Secure File Share?

Secure File Share should only be used for sharing files that contain confidential data. The University Data Classification and Risk Matrix provides more information to help determine the type of restricted data your document may contain, and how best to share/transfer the file to another individual. For standard file sharing services, individuals should use Microsoft OneDrive.

How do I use the new Secure File Share service? 

Requesting a Secure File Share Library (Individual Employees)

  1. Log in to
  2. Click 'Request your Secure File Share Library'
  3. Review the Wright State University IT Security Policy, select 'Yes' and hit 'Submit'
  4. Your Secure File Share Library will be automatically set up (this process takes under a minute), and will appear in the 'Files shared with you' menu on the bottom half of the Secure File Share homepage

Sharing a File or Folder

Important Notes:

  • If you request a file, be sure to follow up with the user.  These are classified as spam by many providers because they're asking the user to provide information to an unknown point.
  • Links to anonymous users are valid for 30 days.
  • Files collected in this site can be moved or copied to any other SharePoint site where you have access to do so and permission to store that particular data; just select the files or folders and choose Move or Copy at the top.  There is no requirement to download in between.
