Fable

Human risk management against AI threats

Overview

Fable Security provides a human risk management platform that defends against AI-powered attacks by measuring each employee’s risk from identity, email, devices, and behavior, then giving real-time coaching through video, chat, or email. It creates a live risk view for every employee and delivers immediate guidance when risk is detected, plus same-day threat briefings and tools to govern sanctioned and shadow AI use, with dashboards and KPIs for security teams. Unlike tools that focus only on tech controls, Fable emphasizes changing employee behavior and governing AI use to achieve measurable outcomes. Its goal is to reduce human susceptibility to AI-driven attacks and show clear risk reductions to leadership and auditors through concrete KPIs.
