What is Doppel?

Doppel describes itself as a social engineering defence platform. Its brand protection product finds and takes down impersonation, fraud and counterfeit attacks across domains, social media, ads, the dark web, app stores and messaging, linking related assets into a threat graph so that a whole campaign can be dismantled. Takedown workflows use language models trained on expert data under human oversight, and Doppel states a median takedown time of under 10 hours across domains, social media and paid ads, with phishing URLs mitigated in a median of 12 minutes. It also sells executive protection, phishing simulation, security awareness training and email security. Founded in 2022, Doppel raised a $70 million Series C led by Bessemer Venture Partners in November 2025 at a valuation of more than $600 million.

Best for: Organisations that want brand protection, executive protection and employee phishing defence from one vendor
