SCOTTSVILLE, Va.–()–Castle Shield Holdings, LLC., today released the first version of its Hermes secure email encryption add-in for Microsoft Office Outlook. Hermes uses strong elliptic curve Diffie-Hellman (ECDH) asymmetric encryption protection and the company’s licensed quantum-resistant symmetric Polymorphic Encryption Core (PEC) algorithm that is FIPS 140-2 validated and certified. Hermes works with the Microsoft Outlook Windows client and integrates seamlessly into the current Outlook menu and ribbon options.

The Hermes Outlook Add-in seamlessly encrypts both the message content and attachments with zero latency, producing productivity enhancements while providing the most advanced encryption ensuring your emails are secure, private, and safe. Unlike some of the other available add-ins that create special links to send attachments and then insert those links in the email message, Hermes lets users compose an email and add attachments as they normally do today. The sender then clicks the secure “Encrypt” button and the add-in automatically handles encryption for both the email content and attachments. Recipients receive the encrypted email message as they would any other email, and they have a menu option to decrypt the message at their convenience. Once the email has been read and closed, it remains encrypted on the employee’s desktoplaptop. Hermes automatically encrypts emails and securely manages the exchanging of encryption keys for users. No other encryption provider provides such a seamless user experience.

“Castle Shield continues to work with enterprises to keep their most prized asset (i.e., their data) secure, private, and safe. With today’s release of Hermes, our holistic approach to cybersecurity now includes data-in-transit via the Outlook Windows email client. There are other Outlook email add-in solutions and encryption email providers however, Hermes includes our quantum-resistant, FIPS 140-2 validated and certified symmetric encryption algorithm in addition to leveraging today’s best-in-class ECDH asymmetric public key encryption (PKE) algorithms,” said Dr. Milton Mattox, Chief Technology Officer at Castle Shield.
