Outlook: Fonts in Outlook for iOS and Android

🚨 The Signal: Outlook for iOS and Android now supports custom fonts in emails. This change primarily affects email presentation, with minimal direct security posture implications, but could indirectly impact data loss prevention (DLP) visibility.

The Impact

End users gain new formatting options, posing a low security risk related to content rendering and potential DLP bypasses.

  • End users: New formatting options could lead to inconsistent email presentation.
  • Security teams: Potential for obfuscation in content, slightly complicating DLP analysis.
  • Compliance teams: Minor risk of content rendering issues affecting audit trails.

The Action

  1. Review existing Data Loss Prevention (DLP) policies to ensure they account for varied font rendering.
  2. Communicate to users about appropriate use of fonts for official communications.
  3. Monitor user feedback regarding email readability and presentation issues.
