Fable Security’s human risk management platform uses a proprietary framework to analyze real-time signals from identity, cloud, access, endpoint, and productivity systems to detect risky behavior.

AI uses the collected data to create personalized interventions—including chats, automated workflows, nudges, and video briefings—designed to educate employees.

These interventions are context-aware, aligned with each employee’s role and behavior, timed for moments of increased risk, and delivered via channels like email and Slack.

“The system learns from the actions people take and assesses risk anew—a first-of-its-kind, closed-loop engine for continuously driving down human risk for enterprises,”

the company explained.

Fable Security was established in 2024 by Nicole Jiang (CEO) and Sanny Liao (CPO), both of whom were founding members of Abnormal AI (formerly Abnormal Security), a company focused on human behavior security for email and SaaS platforms.

Backed by investors including Greylock Partners and Redpoint Ventures, Fable has secured $31 million across its seed and Series A funding rounds.
