Secure Email Threat Defense, a cloud-scale advanced email security layer, harnesses AI powered detections to provide comprehensive protection against advanced email threats, integrated as an API-based supplemental control or with the addition of new pre-delivery inline gateway protection. It provides the most comprehensive protection against damaging and costly email threats that compromise your organization’s brand and operations. Email Threat Defense uses advanced threat detection systems leveraging multiple detection engines that simultaneously evaluate different portions of an incoming email to uncover known, emerging, and targeted threats.
