Sending a secure message

1. Log in to SDS Enterprise.
2. Write the message as you usually would using your e-mail software.
   Use HTML format to write messages. Stormshield Data Mail does not support rich text format (RTF) as it may cause information loss.
3. If you wish to sign the message, in the Security area in the Message tab, click on . E-mail signatures in PGP format are not supported.
   - or -
   If you wish to encrypt the message, in the Security area in the Message tab, click on .
   
   The lower banner Stormshield Data Security appears in the message window and displays the security options you selected.
4. In the lower banner, click on Edit... to select the format in which secured messages will be sent – S/MIME or PGP. This option is only available if PGP was configured in the policy. For more information, see the SDS Enterprise Administration Guide, sections Configure Stormshield Data Mail and Configure Corporate Directories.
5. Click on Send.

Your sent message is stored in your folder (Sent items by default), secured with the security options you have selected. If you have selected encryption, the message is automatically encrypted with your own public key. It will be decrypted when you open it.

NOTE
Editing a secure message directly in the outbox is not supported.

You can also encrypt and sign your messages by applying Microsoft Purview Information Protection sensitivity labels.

Automatic message encryption and signing can be associated with the use of labels. They are defined in the security policy. For more information about this Microsoft feature, see the Microsoft Purview Information Protection product documentation.

For more information on the use of sensitivity labels in the policy, see the SDS EnterpriseAdministration Guide, section Configuring Stormshield Data Mail.

The use of Microsoft labels is complementary to the use of the Encrypt and Sign options of the SDS Enterprise Agent, described above.
