Secure Email for Encryption

Secure Email can be used to encrypt email messages and attachments when sending from a CUIMC email account to an address outside of approved Organized Health Care Arrangement (OHCA) email systems listed below.

If you are unsure whether an email message or attachment being sent outside of internally protected email systems contains sensitive data, you must contact your supervisor or the Office of HIPAA Compliance before initiating the email communication.

We also do not recommend sending a secure email a mailing list.
