Plain text formats

Any extension not listed above is scanned as plain text. For example, .txt, .csv, .html and source code files.

We do not currently support scanning “Strict OOXML” Office documents. These files will have either .docx, .pptx, or .xlsx extensions. When scanning, these files will be skipped, and will show up as unsupported in attachment scan exports.

Enabling and Disabling Attachment Scanning

We recommend leaving attachment scanning enabled, for the best security coverage. Nevertheless, you can turn attachment scanning on or off by navigating to the settings page, and toggling the “Scan attachments” setting.

Exporting Information About Scanned Attachments

To get information about which attachments Security for Confluence scanned, skipped, or failed to scan, you can export information about scanned attachments. These exports are CSV formatted with the following columns:

  • Space key

  • Parent page title

  • Parent page ID

  • File name

  • Attachment ID

  • Attachment version number

  • File Size

  • Scan status - will be one of the following:



    • FAILED

  • Reason for not scanning - If the file is not scanned, then this will have a reason code:



    • TOO_BIG






  • Error message - an optional error message which may indicate why scanning the attachment failed.

From the Soteri Dashboard, you can export attachment scan information for all attachment versions in all spaces you can view reports for:

From the Security Analysis page, you can export attachment scan information for a specific space:

You can also export this information using our REST API.
