RECATOOLS Verdict

Abnormal Security is a leading AI-native email and cloud-collaboration security platform that uses behavioral models to detect business email compromise, phishing, and account takeover that traditional gateways miss. It deploys via API integration with Microsoft 365 and Google Workspace, so onboarding is fast and low-friction, and detection efficacy is widely respected among enterprise security teams.

It is built for mid-market and enterprise budgets: pricing is quote-only and premium, and it overlaps with existing secure email gateways, so smaller ASEAN organisations may find it hard to justify. The API is for platform integration rather than a broad developer surface. Strong choice if email-borne social engineering is your top risk and you have the budget.

Notable facts

  • Abnormal Security detects BEC attacks with 99.75% accuracy — compared to 60% for traditional secure email gateways — because it analyses behavioural anomalies rather than malicious links.
  • The platform processes over 45 billion threat signals per month to build its behavioural models for each protected organisation.
  • Business email compromise attacks cost global organisations over $55 billion from 2013 to 2023 according to the FBI — the exact threat Abnormal was designed to stop.

What types of attacks does Abnormal prevent?
Business email compromise, vendor invoice fraud, phishing, account takeover, and social engineering attacks.
Is Abnormal suitable for mid-size companies?
Primarily enterprise. Pricing is typically annual per-user contracts with a minimum size threshold.
How long does deployment take?
Typically 30 minutes. The API integration requires no infrastructure changes.
