To customize both the appearance and content of messages that are displayed to users, you can upload HTML files to Sophos UTM. As a guide, Sophos provides several sample templates. These templates show you how to use variables that can dynamically insert information that is relevant for individual user messages. For example, if a file is blocked because it contains a virus, you can include a variable that inserts the name of the virus that was blocked.
You can upload custom versions of Sophos UTM notifications, including block messages, status messages, error messages, and authentication prompts. The four sample templates contain working examples of variables as well as several sample images. Either use the sample templates as a basis for your custom messages and notifications or upload your own HTML files. Valid variables are described in Using Variables in Sophos UTM Web Templates in the Sophos Knowledge Base.
If you want to use the text from a message configured on the Web Messages tab, you can insert the appropriate variable in your custom template. For more information, see chapter Web Messages.
To download the sample templates and images, click the link below, and save the .zip file:
Note – The zip file contains examples with and without embedded images. If an image is embedded into an HTML file, you do not need to upload the corresponding image.
Once you have edited and saved your custom template, you are ready to upload it to Sophos UTM.
