SPX Templates
SPX (Secure PDF Exchange) encryption is a next-generation version of email encryption. It is clientless and extremely easy to set up and customize in any environment. Using SPX encryption, email messages and any attachments sent to the Sophos XG Firewall device are converted to a PDF document, which is then encrypted with a password. You can configure the Sophos XG Firewall device to allow senders to select passwords for the recipients, or the server can generate the password for the recipient and store it for that recipient, or the server can generate one-time passwords for recipients.
When SPX encryption is enabled, there are two ways how emails can be SPX encrypted:
User can download the Sophos Outlook Add-in from Sophos XG Firewall's User Portal. After having it installed, an Encrypt button is displayed in the Microsoft Outlook user interface. To encrypt a message, the user needs to click the Encrypt button and then write and send the message. Only if something goes wrong, for example the sender does not enter a valid password, a notification will be sent, if configured.
If you do not use Outlook you can also trigger SPX encryption by setting the header field
X-Sophos-SPX-Encrypt to yes.
In the Data Protection feature, you can enforce SPX encryption for Emails containing sensitive data (see Device Configuration > Protect > Email > Email Scanning Rules .
The encrypted message is then sent to the recipient's mail box. Using any PDF reader, the recipient can decrypt the message with the password that was used to encrypt the PDF. SPX-encrypted email messages are accessible on all popular smartphone platforms that have native or third-party PDF file support, including Android, IOS, Blackberry and Windows Mobile devices.
The SPX template defines the layout of the PDF file, password settings and recipient instructions. You can also define different SPX templates. So, if you are managing various customer domains, you can assign them customized SPX templates containing for example different company logos and texts.
