Email security teams are buried in alerts. Behavioral AI vendors say they have an answer.
Phishing, BEC and account takeover noise keeps SOCs busy. A new webinar pitches behavioral detection as the way to cut through it.
Email remains the cheapest, most reliable entry point for criminal crews — and the resulting alert volume is breaking SOC teams.
Phishing, business email compromise and account takeover (ATO) attacks now drive a significant share of incident-response calls. Analysts spend hours triaging look-alike domains, suspicious OAuth grants, mailbox forwarding rules, and impossible-travel logins. Most of it is noise. Some of it is a wire fraud in progress.
That imbalance is the subject of an upcoming industry webinar making the rounds this week. The pitch: behavioral AI can automate the bulk of detection and response work that currently eats analyst time.
Who's making the argument
The vendor community pushing this approach — Abnormal, Sublime, Material, and others in the API-based email security space — has spent the last two years arguing that signature and reputation-based filters miss the modern threat. Their counterproposal is to baseline normal user behavior, then flag deviations: a CFO who never logs in from Lagos, a vendor thread that suddenly switches banking details, an internal account quietly creating inbox rules to hide replies from the real owner.
The webinar frames the problem in operational terms rather than threat terms. Alert fatigue. Mean time to respond. Analyst burnout. These are the metrics security leaders are being measured on, and they are getting worse.
Why the volume keeps climbing
Three forces are compounding.
Generative AI has stripped the obvious tells out of phishing lures. Grammar is clean. Tone matches the impersonated executive. Reply chains look plausible. Secure email gateways tuned for spammy keywords miss most of it.
Attackers have also moved upstream. Initial access brokers now sell validated Microsoft 365 and Google Workspace credentials by the hundred, often harvested through adversary-in-the-middle kits like Tycoon and EvilProxy that defeat standard MFA. Once inside, the activity looks like the legitimate user — because, from the mail server's perspective, it is.
And BEC payouts remain enormous. The FBI's IC3 has tracked BEC losses above $2.9 billion annually, dwarfing reported ransomware extortion. See the latest figures at ic3.gov.
The automation pitch
Behavioral AI vendors argue that the only way out is to let models auto-remediate the high-confidence cases: pull the message from every inbox, revoke the OAuth token, kill the session, force a password reset, and write the ticket. Analysts review the model's decisions rather than triage every alert from scratch.
Skeptics note the obvious risk. A model that auto-quarantines legitimate vendor mail can break a business faster than a phish can. Tuning thresholds, and trusting them, remains the hard part.
The webinar is registration-gated and aimed at security operations leads and email admins evaluating whether to replace or augment their existing gateway.
