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]

Agentic AI automates takedowns and issues removals via platform APIs and escalation paths, supported by the Doppel SOC.[7]

Doppel Simulation delivers threat-informed campaigns across email, voice calls, meeting apps, and messaging channels, along with tailored, deepfake-enabled training content. Simulations cover email, voice calls, SMS, Microsoft Teams meetings, Zoom Meetings, and messaging channels like Telegram. Doppel Simulation offers attack simulations and security awareness training derived from live campaigns mapped via the Threat Graph. Voice and email simulations test for weaknesses or gaps in an outsourced helpdesk or BPO. Doppel offers a library of actor-led and AI-generated security and compliance training videos, and can create deepfake-driven custom video content. Training can be conducted as a part of a simulation campaign or run independently. Doppel also provides personalized, AI-driven coaching based on user behavior during simulations.[1][9][10]

Doppel sells agentic email security built on external attack infrastructure intelligence from the Doppel Threat Graph that disrupts the attack at the infrastructure level. Instead of only quarantining a message, Doppel takes down the sending infrastructure and malicious links behind every phish. Doppel Phishing Triage is an AI-native email phishing triage engine that gives employees a way to report suspicious emails and gives security teams a way to evaluate and remediate them. Malicious emails are automatically removed from the inbox. Insight from Phishing Triage can be used to create training content and simulation campaigns. AbuseBox ingests, validates, and escalates threats for rapid takedown, instead of letting reports sit in a shared inbox.[1][11][12][13]

Doppel Vision integrates with existing security systems. Doppel supports a bi-directional sync with Splunk to streamline threat intelligence and takedown workflows, and Doppel also enriches Elastic SIEM through a bi-directional sync. Doppel log and threat analytics data can be read in Airtable, and takedown requests can be pushed back to Doppel. Doppel supports integrations and APIs for platforms such as SIEM, SOAR, identity, ticketing, Microsoft 365, and Google Workspace. 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]

Doppel serves organizations across financial services, technology, healthcare, retail, media, government, and crypto. Doppel is designed to maximize the effectiveness of lean security teams. Teams can begin with Digital Risk Protection, Human Risk Management, or Email Security based on their highest-risk exposure. Hundreds of companies use the Doppel platform to protect their brand and people from social engineering attacks. Doppel covers external and internal attack surfaces including domains, social media, messaging platforms, paid ads, app marketplaces, email, and dark-web signals, with coverage varying by product and use case.[1][3][11][14]
