Cyera, an AI-native data and security platform focused on protecting enterprise data and artificial intelligence systems, has raised $400m.
The company has secured $400m in a Series F funding round led by funds managed by Blackstone, with participation from existing investors Accel, Coatue, Cyberstarts, Georgian, Greenoaks, Lightspeed Venture Partners, Redpoint, Sapphire, Sequoia Capital and Spark.
The raise brings Cyera’s total funding to more than $1.7bn and values the business at $9bn, tripling its valuation compared with a year ago.
Founded to address the growing complexity of enterprise data environments, Cyera provides organisations with unified visibility and control over sensitive data as AI adoption expands. Its platform is designed to help enterprises secure data across cloud, on-premise and hybrid environments, while enabling teams to govern how data is accessed, used and shared by AI systems and autonomous agents.
The company said the new funding will be used to accelerate product innovation, expand its global footprint, deepen ecosystem partnerships and bring on additional talent as customer demand continues to grow. Cyera is also doubling down on developing AI-native security capabilities that allow enterprises to move quickly with AI adoption without compromising data protection or governance.
The funding comes amid increasing concern that AI deployment is outpacing safeguards. Industry research has highlighted that weak governance of autonomous systems could lead to major disruptions for large enterprises over the coming years. Cyera said organisations that succeed will be those able to govern AI systems effectively while still unlocking their full potential.
The company’s growth metrics underline the scale of opportunity. Cyera reported more than 3.4x revenue growth and said it now secures data and AI workloads for around 20% of the Fortune 500, spanning sectors including financial services, retail, healthcare, technology and telecommunications. Over the past year, the business has tripled its workforce to more than 1,100 employees, expanded operations to 15 countries across North America, EMEA and APAC, and launched strategic partnerships with Microsoft Purview, AWS and Cohesity.
Cyera co-founder and CEO Yotam Segev said, “AI is reshaping the foundations of how every organization operates, and our mission is to ensure that this transformation happens securely. Enterprises want to move quickly, but they also recognize that AI without data security and governance is a risk they cannot afford. This funding strengthens our ability to protect the world’s most sensitive information and help organizations unlock the full potential of AI with confidence. Securing AI isn’t just a technology challenge, it’s the new cornerstone of enterprise trust, and Cyera is committed to leading that shift.”
Blackstone Senior Managing Director Vishal Amin and Senior Managing Director and Head of the Israel office Yifat Oron said, “Major platform shifts create rare opportunities for category-defining companies, and Cyera is at the center of one of those moments. Cyera’s AI-native platform gives enterprises unified visibility and control of their data, helping eliminate blind spots and accelerate secure AI adoption. Its rapid enterprise traction underscores how mission-critical Cyera has become in modern data security, and we’re excited to support its continued growth and innovation as the need for AI security only expands.”
Blackstone Chief Security Officer Adam Fletcher said, “AI is fundamentally changing the enterprise risk landscape, and data has quickly become one of the fastest-growing and least understood attack surfaces. The move toward unified data security platforms reflects how enterprises are thinking about securing sensitive information as AI adoption accelerates. An AI-native approach aligns with the need for clearer visibility and stronger governance as digital systems and data usage continue to evolve.”
Jon Raper, Chief Information Security Officer at Chevron, said, “As someone responsible for safeguarding the information security strategy and digital infrastructure of a global energy company and a critical part of U.S. infrastructure, I see firsthand how foundational data security has become. Organizations need clear visibility and strong controls to protect sensitive data across increasingly complex environments. That clarity is essential to securing people, assets, and reputation, and to maintaining the trust and resilience required to operate safely and reliably, both at home and around the world.”
