Abnormal AI

Abnormal AI (formerly Abnormal Security) is a San Francisco based cloud email and human-behavior security company whose behavioral AI platform protects Microsoft 365 and Google Workspace against phishing, business email compromise, vendor fraud, account takeover and misdirected email. The platform is API-first: it integrates with Microsoft and Google over their APIs rather than by rewriting MX records, and every capability in the Abnormal Portal — threats, cases, AI Security Mailbox, employee and vendor insights, audit logs, RBAC roles and users, security posture management and dashboard aggregations — is also reachable through the Abnormal Security Client API, a bearer-token REST API published as OpenAPI 3.0.3 on SwaggerHub with separate US and EU production hosts. Abnormal also streams the same event data to SIEM and SOAR platforms over near-real-time webhooks.

Abnormal AI publishes 1 API on the APIs.io network: Abnormal Security Client API. Tagged areas include Company, Security, Email Security, Cybersecurity, and Threat Intelligence.

The Abnormal AI catalog on APIs.io includes 1 event-driven AsyncAPI specification.
