Darktrace / EMAIL vs. Mimecast Advanced Email Security

Darktrace / EMAIL secures email and collaboration by training exclusively on each organization’s own communication patterns, not shared threat intelligence. It builds a Unique Behavioral Profile for every user – spanning email, identity, DLP, and human risk – to catch novel phishing, business email compromise, and account takeover that signature-based tools miss by design. It’s recognized as a Leader in Gartner’s Magic Quadrant and in the 2025 Voice of the Customer for Email Security Platforms.

Email Security, Cloud Integrated (CI) protects organizations against all forms of email-based attacks, from phishing and credential theft to ransomware and zero-day threats. This solution deploys behind M365 to collect emails after they have passed through Microsoft security, reinspect them, and take action as needed. With a setup time of just four minutes and out-of-the-box settings designed to optimize security immediately, Email Security CI delivers best-in-class efficacy in the simplest way possible.
