Generative AI has erased the tells your email security relied on

Attackers now use generative AI to write phishing that passes the grammar, formatting, and authentication checks legacy tools were built to catch. 70% of phishing emails now pass DMARC authentication, and deepfake audio and video are adding new impersonation vectors to business email compromise campaigns. Security stacks have grown more complex without growing more effective — 83% of malware breaches are email-driven and 54% of ransomware originates from phishing. Tools trained on other companies' threat data simply can't catch attacks built specifically for one organization.

Why behavioral defense catches what rules can't

Darktrace / EMAIL trains exclusively on your organization's own data — never a shared, cross-customer model. It builds a Unique Behavioral Profile for every user from relationships, tone, sentiment, content and link-sharing patterns, and thousands of other data points, so it consistently catches what other tools don't:

• 17% of threats leading SEGs miss on arrival
• 55% of the emails it catches had already bypassed every existing native security layer
• 38% of attacks used social engineering techniques never seen before

It operates autonomously while keeping every decision in your control, and spans email, identity, DLP, and collaboration through one connected behavioral model — one reason 75% of Darktrace's email customers have removed their SEG entirely, relying on Darktrace alongside native Microsoft or Google protection instead of paying for a duplicate layer.

What you'll learn

This brief walks through how Darktrace / EMAIL detects BEC, spear-phishing, and novel social engineering across inbound, outbound, and lateral mail; flags account takeover through behavioral baselines per SaaS account, catching anomalous logins and session token misuse before rules trigger; catches misdirected mail and sensitive data loss through behavioral context rather than dictionary matching or labels; and identifies AI-generated phishing and deepfake impersonation that eliminate the formatting errors legacy tools depend on. You'll also see how packaging scales from Core through Advanced and Complete, and hear directly from a CISO whose real-world detection rate outperformed his own expectations.
