TL;DR: AI-generated phishing, business email compromise, and lateral phishing are evolving faster than legacy email security models can reliably detect or remediate, according to Abnormal AI's webinar preview on evaluating email security in 2025. The practical issue is not whether AI is present, but whether controls can prove real-time response under modern threat conditions.
NHIMG editorial — here’s why we think this discussion matters
Questions worth separating out
Q: How should security teams evaluate AI-driven email protection tools?
A: They should evaluate whether the tool can detect adaptive phishing, correlate email risk with identity signals, and trigger response actions fast enough to matter.
Q: Why do AI-generated phishing attacks weaken legacy email security models?
A: They weaken legacy models because attackers can generate convincing, varied, and context-aware content faster than signature-based or pattern-based controls can adapt.
Practitioner guidance
- Map email compromise to identity response paths Define what happens when a mailbox is suspected compromised, including session revocation, credential reset, access review, and mailbox isolation.
- Test real-time remediation against adaptive phishing Run controlled simulations that measure how quickly the platform can quarantine messages, disable links, and reduce exposure after delivery.
- Tie email alerts to privileged access monitoring Correlate suspicious email activity with privileged sign-ins, delegated access, and high-risk approvals so the SOC can see whether a mailbox event is becoming an access event.

Email security is now an identity control problem, not just a content-filtering problem. AI-generated phishing, BEC, and lateral phishing all use email as the delivery layer for identity abuse. The critical failure is that many programmes still treat inbox defence as isolated from authentication, session control, and access recovery. Practitioners should evaluate email security as part of the identity attack surface, not a separate productivity tool.
A few things that frame the scale:
- 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, according to The State of Non-Human Identity Security.
- Lack of credential rotation is cited as the top cause of NHI-related attacks by 45% of organisations, followed by inadequate monitoring and logging at 37%.
A question worth separating out:
Q: How do organisations know if email security is actually reducing identity risk?
A: They should measure how quickly suspicious messages are quarantined, how often account-level response is triggered, and whether compromised accounts are contained before they can be reused. If the control cannot shorten exposure or limit reuse, it is not materially reducing identity risk.
