Data security startup Cyera has announced a $400 million Series F funding round, valuing the company at $9 billion. The funding comes as enterprises face rapidly growing data volumes and heightened security risks driven by widespread AI adoption.

The round was led by funds managed by Blackstone, with continued support from existing investors including Accel, Coatue, Lightspeed, Redpoint, Sapphire, Sequoia, and others. With this raise, Cyera’s total funding now exceeds $1.7 billion.

Cyera focuses on Data Security Posture Management (DSPM), helping organizations discover where sensitive data resides across cloud platforms and databases, understand how it is accessed, and identify security gaps before they lead to breaches or compliance failures.

According to the company, the rapid expansion of AI workloads has intensified both the scale of enterprise data and the urgency of protecting it. Cyera says this trend has helped it onboard one-fifth of Fortune 500 companies as customers and achieve more than 3x revenue growth over the past year.

Why it matters: As AI becomes deeply embedded in enterprise operations, data security is emerging as a foundational requirement rather than an afterthought. Cyera’s latest funding highlights how investors are betting on DSPM as a critical layer for enabling safe, scalable, and compliant AI adoption.
