Cyera, which helps enterprises protect sensitive information while adopting artificial intelligence, has secured $540m in a Series E funding round.
The round was led by Georgian, Greenoaks, and Lightspeed Venture Partners, with additional backing from existing investors Accel, Coatue, Cyberstarts, Redpoint, Sapphire Ventures, Sequoia Capital, and Spark Capital. This new investment brings Cyera’s total funding to over $1.3bn and doubles its valuation to $6bn, less than four years since the company’s inception.
Cyera’s platform enables organisations to locate, classify, and protect sensitive data across their systems, providing security for enterprises as they increasingly adopt generative AI, copilots, and large language models. As AI usage accelerates across industries, securing the data that powers these technologies has become an urgent challenge. Cyera’s rapid growth reflects the growing demand for AI-native security solutions.
The company plans to use the latest funding to expand its product offerings, pursue strategic acquisitions, hire additional talent, and further strengthen its presence in both existing and new global markets. This expansion aims to meet increasing demand for secure and responsible AI adoption at scale.
Cyera has experienced significant momentum over the past 18 months. Its enterprise customer base has grown 353% year-over-year among Fortune 500 companies. It also acquired Trail Security to launch Omni DLP, an AI-native data loss prevention product. The company has expanded its operations into 10 countries and grown its workforce to nearly 800 employees worldwide, while securing major partnerships with global system integrators to extend its reach.
“Investors are doubling down where the market is moving and where there is proven traction. AI runs on GPUs and data. Cyera’s focus on data security is the most critical capability the enterprise needs to adopt AI responsibly,” Cyera co-founder and CEO Yotam Segev said. “Across the board, we’re hearing the need for enterprises to push hard on AI, yet they must move fast without compromising security and control. This funding allows us to scale our platform and team to meet the growing global demand for secure, responsible AI adoption.”
Georgian lead investor Steve Leightell said, “We backed Cyera early because we believed in the team and the vision, particularly its focus on AI adoption protecting data across the enterprise. We believe that Cyera is leading in the category, and we are excited to invest further to support this next stage of growth.”
Lightspeed Venture Partners partner Guru Chahal said, “When we spoke to CISOs and security leaders, Cyera was the name that kept coming up. What stood out wasn’t just the technology; it was that customers saw Cyera as the only platform capable of securing data at the speed and scale that AI now demands.”
Greenoaks partner Patrick Backhouse said, “Enterprises are drowning in data, scattered across clouds, databases, and applications, often unaware of where their most sensitive information actually lives. AI has turned this blind spot into an existential risk. We believe Cyera has built the world’s best data security platform, with a classification engine that is dramatically better than the rules-based paradigm, and which has earned genuine love from CISOs across industries. Truly new pillars of security are rare, but we believe data security is fast becoming one of them, and we are proud to partner with Cyera as they lead the way.”
Elsewhere, Maze, an AI-native cloud security platform, has secured $25m in a Series A funding round aimed at tackling the growing challenge of vulnerability management.
Founded less than a year ago, Maze focuses on resolving cloud security vulnerabilities using AI agents that operate more like humans rather than relying on static rules. Its technology allows organisations to investigate, triage, and automatically remediate vulnerabilities, reducing the manual workload on security teams.
