About Doppel

Doppel sells an AI-powered platform that unifies Digital Risk Protection, Human Risk Management and Email Security. Doppel designs an agentic platform for social engineering defense that protects organizations from AI-powered impersonation, fraud, and social engineering by dismantling attacker infrastructure and building resilience through training and simulation. The Doppel Threat Graph connects spoofed domains, fake profiles, impersonated ads, and malicious texts into a single interactive graph of an impersonation campaign. Doppel Platform is the core platform that powers Brand Protection, Executive Protection, and Simulation. The platform ingests signals from domains, social media, ads, messaging apps, and the dark web, then uses a real-time Threat Graph to detect, correlate, and dismantle attacker infrastructure.[1][3][4][5]

Doppel’s Digital Risk Protection detects and eliminates external threats across social media, domains, marketplaces, and beyond, using autonomous action to disrupt attacks and remove malicious activity. Doppel brings Brand Protection, Executive Protection, and Threat Graph Intelligence together to continuously identify, prioritize, and take autonomous action on threats in real time. Doppel continuously monitors for brand impersonation, phishing domains, fake apps, fraudulent paid ads, and more across social media, marketplaces, messaging platforms, the dark web, and other digital channels. Agentic AI takes down threats across registrars, platforms, and ad networks, and expert analysts handle complex escalations.[3][6]

Malicious emails are automatically removed from the inbox. Insight from Phishing Triage can be used to create training content and simulation campaigns.

Doppel Vision integrates with existing security systems.

Doppel gives teams a focused way to detect abusive ads and landing pages and pursue removal on Google Ads and connect the evidence to other attack infrastructure.[5][7][14]
