    How to send encrypted email with Mimecast

    Mimecast Secure Messaging protects sensitive data by making it easy for users to send and receive secure messages, and enabling policy-initiated secure messages at the email encryption gateway for an added layer of security. 

    Here’s how it works: 

    • When employees need to send an encrypted email, they simply create a new email in Outlook and select a Send Secure checkbox on the Mimecast for Outlook tab. Secure messaging can also be automatically triggered when email content or attachments meet certain policy criteria.
    • Once the user presses Send, the email and attachments are securely uploaded to an email server on the Mimecast cloud, scanned for malware, checked against email privacy, content and data leak prevention (DLP) policies, and then stored in a secure AES-encrypted archive.
    • A notification message is sent to the recipient of the email, directing the recipient to log into the Secure Messaging portal where they can read and reply to secure messages and compose a new message to the original sender.
