TL;DR: Threat actors are already using generative AI, malicious GPTs, and SaaS tool abuse to exploit human trust, while organisations still relying on static rules and perimeter tools lack the architecture to respond, according to Abnormal AI. Behavior-based defense and contextual AI are now baseline requirements, not optional enhancements.

By the numbers:
- The keynote was a 16-minute micro-keynote from CEO Evan Reiser.
Questions worth separating out
Q: How should security teams defend email against AI-enhanced phishing and SaaS abuse?
A: Teams should move beyond static content filters and combine behavioural detection, identity signals, and workflow context.
Q: Why do AI-generated lures challenge traditional email security controls?
A: AI-generated lures can mimic tone, timing, and context well enough to pass rule-based checks that rely on known patterns.
Q: What do security teams get wrong about contextual AI in email defense?
A: They often treat contextual AI as a feature layer rather than a workflow change.
Practitioner guidance
- Audit identity-aware detection coverage Map where your email stack can ingest sender history, message context, and downstream identity signals instead of relying on static content rules alone.
- Review trusted SaaS tool pathways Identify which sanctioned tools can touch mail, chat, ticketing, or file-sharing workflows and verify that their permissions, logging, and alerting are narrowly scoped.
- Measure analyst decision reduction Track whether contextual AI is shortening investigation paths, reducing low-confidence triage, and helping analysts focus on the few cases that actually need escalation.

AI-powered email threats: what IAM teams need to watch?

Static perimeter defense is now a governance failure, not just a tooling gap. The article shows attackers using generative AI and trusted SaaS interfaces to target human trust directly. That breaks the assumption that email security can be handled as a content-filtering problem. The implication is that identity, behaviour, and context must be part of the control model, because the attack now lives inside the trust relationship.
A few things that frame the scale:
- From our research: 80% of identity breaches involved compromised non-human identities such as service accounts and API keys, according to the Ultimate Guide to NHIs.
- Our research also shows that only 5.7% of organisations have full visibility into their service accounts, which helps explain why identity abuse often stays hidden until damage is done.
A question worth separating out:
Q: How do IAM and email security teams work together on AI-driven threats?
A: They should share signals across authentication, access, collaboration, and mail telemetry so that suspicious behaviour can be evaluated in one chain. IAM teams can help identify compromised or misused identities, while email teams can surface the initial interaction. Together they create a clearer view of abuse than either team gets alone.
