Abnormal Security
Abnormal Security — AI-based email security platform detecting BEC, phishing, and account takeover using behavioral baselines.
Our Verdict
Best-in-class AI email security for M365 shops with budget; overkill and pricey for smaller orgs.
Pros
- Behavioral AI catches BEC that signature-based gateways miss
- API-based deployment skips MX record changes
- Strong account takeover detection via login anomalies
- Post-delivery remediation auto-claws back phishing emails
Cons
- Enterprise-only pricing with opaque per-mailbox quotes
- Requires Microsoft 365 or Google Workspace, no on-prem
- Baseline learning period delays full protection
- Limited visibility into detection logic for tuning
Best for: Mid-to-large enterprises on M365 fighting BEC, vendor fraud, and executive impersonation.
Not for: Small teams, on-prem Exchange, or orgs wanting transparent, predictable licensing.
