Stop Advanced Email Attacks with Behavioral AI

Trusted by over 25% of Fortune 500 organizations and rated 99% would-recommend on Gartner Peer Insights.

Abnormal AI enhances Microsoft 365 with an AI-native platform that protects against the full spectrum of modern email threats—without rules, tuning, or policy maintenance. By modeling known-good behavior across every employee and vendor, Abnormal detects subtle behavioral anomalies that signal business email compromise, credential phishing, ransomware, and insider risk—threats that often bypass traditional secure email gateways and native Microsoft defenses.

Deployed in minutes via API, Abnormal ingests thousands of behavioral signals and uses natural language processing (NLP) to evaluate every message’s context, tone, urgency, and intent. This enables the platform to precisely block socially engineered, payloadless attacks that are invisible to legacy filters, without disrupting legitimate business communication.

Beyond inbound protection, Abnormal continuously monitors user behavior and cloud environment changes to uncover signs of account compromise and misconfiguration risk. Whether it’s an attacker exploiting a stolen session token or a dormant admin account suddenly granted risky permissions, Abnormal identifies these anomalies and can automatically remediate them by resetting passwords, terminating sessions, or alerting the appropriate team. The platform also evaluates configuration changes against security benchmarks, surfaces the highest-risk issues, and provides step-by-step remediation guidance, reducing manual audits and helping security teams focus on what matters most.

Abnormal also eliminates busywork for SOC teams by using AI security agents to triage user-reported phishing, remove graymail, and remediate post-delivery threats across all mailboxes and tenants. Every employee receives real-time, AI-generated feedback on their submissions, while security teams gain centralized visibility and campaign-level remediation at scale.

By eliminating advanced email security threats without added complexity, Abnormal empowers employees to stay productive and frees security teams to concentrate on the initiatives that matter most. Get started today with our one-click API integration via Azure Marketplace.
