Standard features in Office 365 provide basic protection. However, in highly regulated B2B environments, such as when transferring financial data or health information, friction points quickly arise in everyday operations.
Not every communication partner uses Microsoft 365. Native encryption often forces external recipients into portals or requires Microsoft accounts. This disrupts business processes and reduces acceptance.
When encryption must be manually activated per email by the user, compliance risks arise due to human error. IT managers lose traceability of critical data leaks.
Your employees send emails as usual from Outlook. Detection of confidential content and encryption (via S/MIME or PGP) occur fully automatically in the background. No add-ins.
