Behavioural AI, built for the era of AI
Email is still where most attacks land, and attackers now use generative AI to write phishing emails with no typos, no template repetition, and nothing for a signature-based scanner to catch. Legacy gateways rely on known threat indicators. That's no longer enough.
Abnormal AI takes a different approach. Rather than matching signatures, our platform learns what's normal for every person, vendor, and app connected to your organisation, then flags what isn't. It's the same model powering protection across email, identity, and AI tools, so a compromised account or a suspicious sign-in doesn't slip through because it landed in a different system.
Why organisations choose Abnormal AI
Over 4,500 organisations, including more than a quarter of the Fortune 500, run Abnormal AI to make automated, critical security decisions every day.
Platform capabilities
Abnormal AI's Behavioural Security Platform covers email, identity, AI, and insider threat from a single behavioural model.
Build a behavioural model of every person and every vendor connected to your organisation: catching the BEC, vendor fraud, account takeover, and AI-generated attacks legacy gateways miss. Detection that tunes itself. Deployed via API in 60 seconds.
Today's identity threats look like normal activity. Identity Threat Protection uses behavioural AI to catch hijacked sessions, abused OAuth grants, and privilege misuse that rules and risk scores miss, then contains threats across email, idP, and SaaS before they escalate.
Gain immediate visibility into every AI tool, agent, and chat by leveraging signals across email, identity, OAuth, and browser activity to assess risk and automatically enforce security policies. By connecting email, identity providers, and OAuth grants, Abnormal begins mapping your AI ecosystem on day one—surfacing unsanctioned tools, over-permissioned agents, and policy violations during your initial review without requiring lengthy integrations or tedious manual audits.
Infiltration Prevention applies Abnormal's behavioural AI to detect synthetic personas and nation-state actors using signals from Workday or Greenhouse, identity providers, and email. Your SOC gets the intelligence that traditional security screenings miss, before access is ever provisioned.
Attune: the behavioural AI engine
Every Abnormal detection runs on Attune, Abnormal's behavioural AI foundation model. Attune builds a bespoke baseline for what's normal, then detects attacks by deviation from that baseline rather than by matching known threat indicators, which means it catches novel campaigns and AI-generated attacks that no rule could anticipate.
