SafeToOpen Email Security

SafeToOpen Email Security analyses every email you receive in Microsoft Outlook and delivers an instant threat verdict — Safe, Caution, or Dangerous — so you never get caught out by phishing, business email compromise (BEC), or social engineering attacks.

How it works

Open any email and click the SafeToOpen button in the ribbon. Within seconds you get a trust score based on deep analysis of the sender, email headers, links, attachments, and domain reputation.
