Cyera is a New York-based data security company that helps large organizations find, classify, and govern their sensitive data, including what their AI systems are allowed to see and do. Founded in 2021, it has become one of the most valuable privately held cybersecurity firms in the world, and in 2026 it raised $600 million at a $12 billion valuation, roughly doubling its price in five months.
What Cyera does
Cyera operates in a corner of cybersecurity known as data security posture management. In plain terms, it helps organizations answer a deceptively hard question: what sensitive data do we have, where does it live, and who or what can touch it. Its platform discovers and classifies information whether it is at rest, moving across networks, or actively in use, then applies controls to reduce risk.
The company says its platform spans more than 100 capabilities across data security posture management, data loss prevention, identity, behavior, and what it calls agentic security. That last category is the strategic logic behind its growth: as enterprises wire AI models and autonomous agents into their systems, security teams need a way to govern exactly what an AI can access. Co-founder and chief executive Yotam Segev describes the company as a "trust layer" for that shift.
A valuation that keeps doubling
Cyera's funding history reads like a stress test of investor appetite. It raised at a $3 billion valuation in late 2024, $6 billion in mid 2025, $9 billion in January 2026, and $12 billion in the latest round, meaning its price quadrupled in under two years. The 2026 round was led by Evolution Equity Partners, with Accel, AT&T Ventures, Blackstone, Coatue, and Spark Capital joining, lifting total funding past $2.3 billion.
That pace reflects a broader pattern in which a small number of category leaders soak up an outsized share of capital while the median startup faces a tougher market. It also tracks enterprise anxiety about AI governance, as companies feed sensitive documents into chatbots and deploy agents that act on data with limited oversight.
Why the timing matters
The raise lands at a moment when corporate adoption of generative AI has outrun the security tooling built to govern it. For investors, that turns data security from a compliance line item into a precondition for AI deployment: if a bank or hospital cannot prove what its AI systems are permitted to access, it cannot safely scale them.
Cyera is betting it can become default infrastructure for that control layer the way endpoint and cloud security tools became standard a decade ago. The risk is that a valuation reached this quickly compresses the room for error and sets a high bar for any eventual public listing, in a crowded market full of well-funded rivals chasing the same AI security opportunity.
