Sending Encrypted Emails

Microsoft Exchange​

Microsoft Exchange provides built-in email encryption that uses end-to-end encryption to protect your sensitive communications. When you include secure or encrypt in the subject line, Exchange automatically encrypts the message and its attachments before sending.

How It Works​

Microsoft Exchange encryption uses industry-standard encryption protocols to ensure that your emails are protected both in transit and at rest. The encryption process:

  • Encrypts the message content - All text, attachments, and metadata are encrypted using strong encryption algorithms
  • Protects in transit - The encrypted message is securely transmitted over the internet
  • End-to-end security - Only the intended recipient with proper authentication can decrypt and read the message
  • Automatic decryption - Recipients using Microsoft 365 or Outlook can automatically decrypt and view the message without additional steps

This method is ideal for sending sensitive information, financial data, or confidential documents that require protection from unauthorized access.

Document Guardian​

Document Guardian is a secure file transfer and encryption service designed for sharing sensitive documents and large files. It provides an additional layer of security beyond standard email encryption and is particularly useful when you need to send files that exceed email size limits.

Key Features​

  • Large file support - Send files and attachments that are too large for standard email (no 35MB limit)
  • Secure file transfer - All files are encrypted during upload, storage, and download
  • Access control - Set expiration dates, password protection, and download limits for shared files
  • Audit trail - Track when files are accessed and downloaded by recipients
