About Doppel
In the era of AI, knowing what’s real is harder than ever. Social engineering threats are sophisticated, multi-channel campaigns. They lurk in your inbox, compromise your email channels, and weaponize fake profiles across social networks to deceive and defraud your people and your brands. Doppel is the agentic social engineering defense platform built to fight AI with AI. Unlike traditional systems that stop at detection and inbox scoring, Doppel delivers real-time disruption. We secure the inbox while executing automated takedowns on malicious sending infrastructures, lookalike domains, and rogue profiles at machine speed. By unifying Digital Risk Protection, Human Risk Management, and Email Security onto a single centralized platform, Doppel shuts down threats at their source. We safeguard every channel, move faster than attack speed, and turn global threat intelligence into a compounding network effect that keeps you ahead of the curve.
