Email Security
Email security that fights back
Agentic email security built on external attack infrastructure intelligence from the Doppel Threat Graph that disrupts the attack at the infrastructure level.
Protecting the best brands
Move beyond passive defenses
Don’t settle for inconsistent, blackbox email security. Increase accuracy and explainability
Doppel Email Security catches what other tools miss, and allows you to take an active role in your company’s defense by dismantling the infrastructure behind the attack. Every detection and investigation is backed by clear, human-readable logic, so your SOC can scale effortlessly to meet AI-driven attack volume, without adding headcount.
Thus far, email security tools have relied on a passive, surface-level fix by removing messages from the inbox. But this approach fails to stop threat actors from repurposing the campaign infrastructure to target the company repeatedly.
Why Doppel Platform
Graph-driven intelligence
Powered by external attack infrastructure intelligence from the Doppel Threat Graph and agentic AI, Doppel Security Email is trained on billions of signals from across the internet to catch what other tools miss and stop the campaign in its tracks.

Email Security that strengthens your perimeter
The threat doesn’t stop with the email, and neither should your defense
Doppel Email Security looks beyond just the message in the inbox. It goes upstream to map out the entire social engineering campaign to dismantle the attack at the infrastructure level and prevent the campaign from spreading in your organization. Powered by intelligence from the Doppel Threat Graph and agentic AI, Doppel Email Security detects phishing attempts with unparalleled accuracy.
Stop the attack, not just the email
When Doppel takes down the infrastructure behind a phish, the same campaign doesn't reach the next inbox. Risk reduction happens at the campaign level, not message by message.
Spot every threat
Each email that hits the inbox is assessed for intent, context, and risk level against billions of signals from the Doppel Threat Graph. Verdicts come from infrastructure context, not just message content, so you catch even the most sophisticated attacks.
Scale the SOC without scaling headcount
Every reported or detected phish becomes an automated investigation, takedown, and policy update. No queues. No backlog. No repeat campaigns.
Natural-language explainability and investigations
Your team interfaces with the system the way the agents do, in plain language and human-readable terms that eliminate ambiguity or hours spent deciphering logic.
Eliminate detection drift
Doppel’s agentic detection stack evolves with attacker tactics, so even novel attacks and zero-days are caught every time.
Social Engineered Threat Training
Phishing attempts inform training and simulation content that helps build employee resilience against the actual attacks they could encounter in the world.

FAQs
Frequently Asked Questions
What is Doppel Email Security?
Doppel Email Security empowers organizations to take an active role in their defense against phishing attacks with unmatched accuracy, agentic disruption, and actionable insights. Powered by external attack infrastructure intelligence from the Doppel Threat Graph and agentic AI, it is trained on billions of signals from across the internet to catch what other tools miss and stop the campaign in its tracks.
How does Doppel differ from other email security tools?
Doppel sits alongside native email tools (like Microsoft 365 or Google Workspace) to catch AI-generated lures, BEC attempts, and impersonation-based attacks that bypass traditional filters.
Doppel can act in-place of Secure Email Gateways in modern tech stacks, or run alongside gateways as the AI-native detection and response layer. Our team can help you identify the best approach.
And finally, other AI-native tools see only the inbox. Doppel sees the whole attack chain. Where competitors quarantine the email, Doppel takes down the infrastructure that sent it.
How does Doppel handle false positives?
Doppel's verdicts come from infrastructure context, not just message content, which yields fewer false positives than behavior-only tools, especially against AI-generated lures with no behavioral baseline. And every verdict is auditable, so you have a clear and easily digestible way to review every decision and tune policies for your organization.
How quickly can Doppel Email Security deploy?
Most organizations deploy in days. API integration with Microsoft 365 or Google Workspace make it easy to get up in running, with no policy changes or mail flow rewrites required.
