Cyera Raises $400 Million to Secure AI Adoption at Scale for Every Enterprise

Cyera, the AI-native data security platform, led by Yotam Segev, Tamar Bar-Ilan, and others, has secured $400 million in funding.

AI now demands a new security model. Public data powered the first wave; proprietary data will drive the next. As agentic AI spreads across enterprises, automated systems generate massive volumes of actions and decisions, expanding exposure.

The real challenge is securing this ecosystem. Legacy security tools cannot see or control the data AI depends on, forcing organizations to choose between restricting access or accepting unacceptable risk. Cyera is positioned to solve this emerging gap.

Cyera positions itself as the unified data and access control plane for global enterprises. The platform evolved from AI-native DSPM for data at rest into a full Data Security Platform covering data in motion, access, identity, business context, and automated remediation. AI Guardian further extended coverage by detecting Shadow AI and securing usage across enterprise chatbots, internal models, and third-party applications.

Across thousands of enterprise interactions, one conclusion emerged: trusted data access forms the foundation of AI security. With new funding, Cyera aims to expand its scalable data-plus-access architecture to secure AI across four pillars: safe employee use of copilots and external AI tools; trusted agentic AI with guardrails and behavioral oversight; protected AI ecosystems and homegrown models from build time onward; and AI-driven security agents that automate detection, investigation, and response at machine speed.

CISOs are entering a new era where security shifts from guardrail to growth driver, enabling AI adoption across the enterprise. Cyera aims to support this transition by giving security leaders the confidence to manage AI safely. Because secure AI spans CDOs, privacy, compliance, legal, and business teams, the platform is being built to serve every stakeholder responsible for data access and protection.
