Hornetsecurity AI Recipient Validation analyzes email communications in real-time to prevent security breaches and data loss by identifying potential issues such as unintended recipients, missing recipients, sensitive information, inappropriate wording, and replies to large distribution lists. It provides instant feedback, allowing users to correct errors before sending emails and learns from user behavior to refine its warnings and suggestions over time. The solution integrates with Microsoft 365 and operates locally within the Outlook client without transmitting email content to Hornetsecurity's servers, while administrators can configure warning scenarios and monitor instances through a dashboard to enhance data privacy awareness.
