Cyera, a major player in AI and data security, has closed a $400 million Series F funding round that brings its total capital raised to over $1.7 billion. The investment, led by funds managed by Blackstone, arrives just six months after the company's previous raise and marks a significant milestone: Cyera's valuation has tripled in the past year to $9 billion.
All existing investors participated in the round, including Accel, Coatue, Cyberstarts, Georgian, Greenoaks, Lightspeed Venture Partners, Redpoint, Sapphire, Sequoia Capital, and Spark. The funding positions Cyera as one of the most well-capitalized security startups in 2025, with more than $1.2 billion raised in just the past 12 months.
The timing reflects a broader shift happening across enterprise technology. AI adoption continues to accelerate, particularly agentic AI systems that can operate with increasing autonomy. But that speed comes with risks. According to IDC's FutureScape: Worldwide Agentic Artificial Intelligence 2026 Predictions, "the early wave of GenAI deployments surfaced a pattern where speed sometimes outpaced safeguards." The research firm predicts that by 2030, up to 20% of G1000 organizations will face significant setbacks due to poor AI agent governance.
Companies are caught between two competing pressures: move fast to capture AI's benefits, or slow down to implement proper safeguards. The winners, IDC suggests, will be those that can govern autonomous systems without limiting their potential. That's exactly where Cyera comes in.
"AI is reshaping the foundations of how every organization operates, and our mission is to ensure that this transformation happens securely," said Yotam Segev, co-founder and CEO of Cyera. "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."
The new capital will fuel several growth priorities. Cyera plans to double down on product innovation, particularly around its AI Guardian platform introduced this year. The company will also accelerate global expansion beyond its current footprint of 15 countries across North America, EMEA, and APAC. Strategic ecosystem partnerships remain a focus, building on existing collaborations with Microsoft Purview, AWS, and Cohesity.
Hiring is another major area of investment. The company has already grown to more than 1,100 team members, a threefold increase in the past year. As demand for AI security expertise continues to outpace supply across the industry, Cyera is positioning itself to attract top talent in engineering, security research, and enterprise sales.
Future development will center on expanding the platform's ability to provide unified visibility and automated safeguards across increasingly complex data environments. As enterprises deploy AI across cloud, on-premises, and hybrid infrastructures, maintaining consistent security policies becomes exponentially harder. Cyera's roadmap addresses this by building deeper integrations and more sophisticated risk detection capabilities.
Cyera was founded with a clear thesis: traditional security approaches weren't built for a world where data moves freely across environments and AI systems access information at scale. The company pioneered the convergence of Data Security Posture Management (DSPM), Data Loss Prevention (DLP), and identity management into a single platform, becoming the first to integrate these previously separate functions.
This year marked another evolution with the launch of AI Guardian, which expands Cyera's offering into a comprehensive security platform designed specifically for AI-driven businesses. The platform gives organizations a single source of truth for their data, along with continuous risk detection and automated protections that follow sensitive information wherever it resides.
The approach resonates with enterprise buyers. In just over 12 months, Cyera has secured contracts with 20% of the Fortune 500, including leading companies in financial services, retail, media and entertainment, healthcare, technology, and global telecommunications. Revenue has grown more than 3.4x during the same period, making Cyera one of the ten fastest-growing companies in the technology sector.
For Blackstone, the investment reflects a conviction that major platform shifts create rare opportunities for companies that get the fundamentals right. The firm manages one of the world's largest pools of capital and typically backs companies at inflection points in their growth.
"Major platform shifts create rare opportunities for category-defining companies, and Cyera is at the center of one of those moments," said Vishal Amin, Senior Managing Director, and Yifat Oron, Senior Managing Director and Head of the Israel office at Blackstone. "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."
The investment thesis is straightforward. AI adoption is creating a new attack surface that traditional security tools weren't designed to protect. Data flows more freely, AI models require access to vast information repositories, and the pace of change makes manual oversight impractical. Organizations need platforms that can keep up.
"AI is fundamentally changing the enterprise risk landscape, and data has quickly become one of the fastest-growing and least understood attack surfaces," said Adam Fletcher, Chief Security Officer at Blackstone. "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."
That perspective comes from someone responsible for protecting Blackstone's own digital infrastructure and sensitive information across a global investment portfolio. Fletcher's team evaluates security vendors from both a practitioner's viewpoint and an investor's lens, making the endorsement particularly significant.
Enterprise customers echo similar themes. Jon Raper, Chief Information Security Officer at Chevron, highlighted why data security has become foundational for critical infrastructure operators.
"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," said Raper. "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."
Cyera's investor syndicate represents some of the most respected names in venture capital and growth equity. Beyond Blackstone's leadership in this round, the company is backed by Accel, Coatue, Cyberstarts, Georgian, Greenoaks, Lightspeed Venture Partners, Redpoint, Sapphire, Sequoia Capital, and Spark. The full participation of existing investors in this round signals continued confidence in the company's trajectory and market opportunity.
