About Fable Security

Fable Security sells human risk management software for the AI threat era, covering phishing and vishing simulation, security awareness training, and employee risk scoring with interventions.[1][5]

Fable Security says AI-written phishing, cloned voices, and deepfakes slip past the red flags training taught. The home page says AI writes flawless phishing, clones a CFO's voice, and joins video calls as a deepfake. Fable Security also says one-size-fits-all training ignores how people actually behave, and that legacy content takes weeks to ship while new AI attack patterns spread in days.[5][11]

The simulation part runs role-specific phishing, voice, and deepfake simulations and feeds every result into the risk picture. The training part sends branded, targeted briefings on new threats within hours.

Fable Security describes a loop in which it picks up risky behavior from the security stack and from phishing, vishing, and deepfake simulations. The Fable Risk Engine scores risk for each employee and cohort and shows the behaviors behind every score. People who need help get a short, personalized intervention in Slack, Teams, or email. Fable then measures whether behavior and risk changed and re-intervenes where they did not.

On deployment, Fable Security says it pulls signals from identity, email, endpoint, SASE, HRIS, and collaboration tools without new agents on employee devices. Fable Security says that when CrowdStrike flags a compromised credential, Fable triggers an automated password rotation.

For behavior change, Fable Security says it customizes AI videos, text-based nudges, and two-way chats based on risk details and the customer's policy. For emerging threats, the security awareness training page describes a Briefing agent that drafts a targeted briefing from a threat report, alert, or policy.[5][12][13][17]

Fable Security also addresses AI use. It says Fable discovers unsanctioned AI use through integrations with IAM, DLP, and browser-based tools. The risk reporting page says Fable generates explainable human risk profiles using behavioral signals instead of static metrics, and ingests written policies and maps them to employee behaviors.[8][9]

Its training page says it delivers training for frameworks and regulations such as PCI-DSS, HIPAA, and NIST.[3][5][7][8][9][10][11][12][13][16][17]
