Recognition underscores Doppel’s continued growth and leadership in Social Engineering Defense as AI transforms the threat landscape

SAN FRANCISCO , Oct. 28, 2026 /PRNewswire/ — Doppel, the Frontier AI Social Engineering Defense (SED) platform, today announced it has been named to the 2026 – 2027 Fortune Cyber 60 list for the second year in a row. Produced in partnership with Fortune editors, Lightspeed Venture Partners, and AWS, the annual list recognizes 60 of the most important venture-backed startups shaping the future of cybersecurity. Selection is based on financial performance, business operations, growth, and cybersecurity market research.

The recognition comes as AI makes phishing and other social engineering attacks more sophisticated, personalized, and easier to scale across multiple channels, exposing the limitations of legacy cybersecurity defenses. Doppel was founded as an agentic platform built to address this new environment and protect organizations across the entire social engineering attack chain. Powered by agentic AI, the platform unifies Digital Risk Protection, Human Risk Management, and Email Security to detect and connect attacks across channels, disrupt the infrastructure behind attacks, and strengthen employee resilience against evolving tactics.

“Being named to the Fortune Cyber 60 for the second consecutive year is a significant moment for our team and a reflection of the progress we’ve made as a company,” said Kevin Tian, co-founder and CEO of Doppel. “As we’ve seen in recent weeks, phishing techniques are becoming more sophisticated, and attackers are more capable than ever before. We’re at an inflection point in cybersecurity. As an industry, we have a responsibility to equip defenders with the technology and resources they need to stay ahead of these threats. I’m proud of what we’ve accomplished so far, and we’re only getting started.”

The recognition adds to a year of continued growth and expansion for Doppel. In 2026, the company expanded its global presence in Japan and Toronto, introduced new capabilities across its Social Engineering Defense platform, including Email Security, and officially surpassed 300 employees. Doppel was also named to Fast Company’s 2026 Best Workplaces for Innovators list and won a 2026 SiliconANGLE TechForward Award in the AI-Powered Threat Detection category.

Fortune Cyber 60 Methodology: The Fortune Cyber 60™ list, developed in partnership with Lightspeed Venture Partners and AWS, recognizes 60 of the most important venture-backed cybersecurity startups that have not yet undergone an IPO, acquisition, or other significant exit. Companies are grouped into three categories of 20—Early Stage, Early Growth Stage, and Growth Stage—and listed alphabetically within each category. Selection is based on financial performance, growth, business operations, and cybersecurity market research, with the final list reviewed and validated by Fortune. The full methodology can be found here.

About the Cyber 60
The Fortune Cyber 60 identifies significant venture-backed cybersecurity startups that have not completed an IPO, acquisition, or other major exit. Companies are grouped by stage rather than ranked, reflecting the distinct opportunities and challenges facing businesses at different points in their development.

About Doppel
Doppel is the Frontier AI platform for Social Engineering Defense (SED), protecting people and brands from AI-powered impersonation, phishing, fraud, and deception through three solutions running on the Doppel Superintelligence Layer. Digital Risk Protection (DRP) sees attacks forming, mapping attacker infrastructure across channels and dismantling it before launch. Email Security defends the inbox, judging every message by the infrastructure behind it and taking that infrastructure down so the campaign can’t retarget. Human Risk Management (HRM) hardens the people attackers target, turning live threats into simulations and training and measuring risk by user and team. Every signal flows through a shared Threat Graph, so a threat seen anywhere strengthens defenses everywhere, and self-healing agents patch every missed detection. Together, they break the social engineering attack chain, advancing Doppel’s mission to protect the world from social engineering attacks every day.
