Encrypt Your Email

spar

You must use encryption if you are emailing anything confidential or classified such as:

  • protected health information (PHI)
  • personally identifiable information (PII)
  • HIPAA information
  • FERPA information
  • educational records
  • credit card information
  • anything protected by governmental or institutional regulations, it must be encrypted

Encryption ensures that protected or sensitive information is not intercepted during email transmission, thus protecting you and the university from potentially costly and reputation-damaging data breaches.

Sending an Encrypted Email

You can enter a descriptive subject line as long as the word encrypt is included somewhere within it. Examples: New Student Information encrypt or Encrypt New Student Information.

Note that words such as "encryption” or “encrypted” will not trigger the encryption process.
