Key Takeaways:

- The firm builds sovereign AI tools for secure, government-controlled national defense.
- Co-founders include former Austrian Chancellor Sebastian Kurz and Shalev Hulio.
Israeli cybersecurity firm Dream Security has raised $260 million in a new funding round, pushing the Dream Security valuation to $3 billion to expand its sovereign AI-powered national defense platforms globally.
Scaling Sovereign Defense
The latest Series C financing round, led by Bicycle Capital and Group 11, nearly triples the Dream Security valuation from its level in February 2025. With participation from Bain Capital Ventures, Antler, and Tru Arrow Partners, Dream has now secured over $410 million in total capital.
The startup, co-founded by former Austrian Chancellor Sebastian Kurz and former NSO Group CEO Shalev Hulio, provides governments with sovereign AI tools that function entirely within state-controlled environments.
“We started three and a half years ago with the vision that the next cyber warfare is going to be AI versus AI and not human versus human anymore,” said Shalev Hulio, Dream’s CEO. “A year ago, we realized that the bad guys of the world, the Chinese, the Russians, North Koreans, the Iranians, are abusing AI to find the weakest link in every country.”
Targeted Technological Solutions
Dream currently offers three primary platforms designed to secure critical infrastructure, such as energy and water grids, against state-sponsored threats. Its “Sphere” platform provides unified cyber-defense, “Hero” functions as an autonomous AI security researcher, and “Atlas” serves as an on-premises AI system for sensitive data analysis.
By ensuring these tools run on government-governed infrastructure, Dream aims to eliminate dependency on foreign technology providers.
“The decisive question for states is no longer whether they will use artificial intelligence, but whether they will also own, operate, and fully control it,” said Sebastian Kurz, president and co-founder of the company. “The future of a nation should never depend on technology it does not control.”
Global Expansion Strategy
The startup, which currently employs roughly 350 people, plans to use the new capital to accelerate its deployment across Europe, Asia, and the Americas.
Executives confirmed plans to open a new office in Munich later this year, signaling a broader push into the German market.
The company continues to compete in the government-technology space, offering tailored models that prioritize data sovereignty and national resilience against increasingly sophisticated, AI-driven cyberattacks.
The latest funding round and growing Dream Security valuation highlight investor confidence in its sovereign AI cybersecurity vision.
