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.

When to Use Abnormal Security

Good fit if you need

  • BEC detection via behavioral baseline for finance teams
  • Account takeover prevention for M365 and Google Workspace
  • Phishing triage automation to reduce SOC alert fatigue
  • Vendor email compromise detection for AP workflows
  • Executive impersonation alerts for high-risk inboxes
