Secure E-Mail Overview Northern Trust offers a secure method to facilitate e-mail communication called Secure E-Mail. This secured approach is supported by PGP Universal encryption software. Encryption software minimizes the potential for unauthorized individuals to view information that is confidential or proprietary by converting an e-mail message and contents into an unreadable format. The message is decrypted on the receivers end by logging in, which converts the message to clear text so that it can be read There are no set-up or usage costs for participating in the secure email program.
