About the Cisco Registered Envelope Service (CRES)

Indiana University uses the Cisco Registered Envelope Service (CRES) to provide protection of certain sensitive information when it leaves the IU network. IU (including the IU Health Sciences community) uses the Cisco Data Loss Prevention appliance (IronPort) to encrypt email containing certain sensitive data, including identifiable medical, personal, and financial information; see About sensitive data at IU and What is protected health information (PHI)?

All outbound messages from IU mail servers to external recipients are scanned for certain potentially sensitive information; if the scan determines that the message is likely to contain sensitive data, it is encrypted, and the recipient is sent email with instructions for accessing and reading the message (see Read a CRES-encrypted message or Read a CRES-encrypted message received at your Gmail at IU, Imail, or Umail account).

For more about CRES, see Cisco's About Registered Envelopes and Registered Envelope Help pages. You can also click Help when on the Cisco site to read context-sensitive help.

If you have problems reading an encrypted message, see If you can't read a CRES-encrypted message or contact your campus Support Center.

If your outbound email message was encrypted and you don't think it should have been, see What should I do if IronPort encrypts my outbound email?
