Enterprise adds API and mixed-mode deployment, account-compromise protection, email link and attachment isolation, and Microsoft 365 outbound data-loss notifications with message blocking. Enterprise + PhishGuard adds managed detections and retractions, threat hunting, fraud and insider-threat response, customized campaign and indicator-of-compromise reporting, and dedicated technical resources.
