What is the Cisco Registered Envelope Service (CRES)?

Indiana University has begun deployment of 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 What is sensitive data, and how is it protected by law? 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 How can I read a CRES-encrypted message? or How can I read a CRES-encrypted message received at my 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 Why can I not 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?
