AI security startup Cyera raised $600 million [1] in a Series G funding round announced June 10, 2026 [4].

The investment reflects a growing corporate urgency to secure data as artificial intelligence agents begin performing autonomous tasks. Organizations currently struggle with a lack of visibility between human activity and the actions of AI agents, a gap Cyera aims to close.

Based in New York City [5], the company now carries a valuation of $12 billion [1]. This latest round brings the startup's total cumulative funding to approximately $2.3 billion [3]. The company was launched by cofounders Yotam Segev, who serves as CEO, and Tamar Bar-Ilan, the CTO [6].

Cyera is positioning its technology as a trust layer for the AI era [7]. The platform is designed to provide the visibility necessary for organizations to monitor how AI interacts with sensitive data and where potential security vulnerabilities exist.

While some reports previously cited a smaller Series E round, the June 10 announcement confirms the Series G milestone [1, 4]. The company continues to scale its operations in the U.S. to meet the demand for AI-native security tools [5].

The rapid valuation climb of Cyera underscores a shift in the cybersecurity market from traditional perimeter defense to AI-native data security. As enterprises deploy autonomous AI agents, the risk of 'shadow AI' and unauthorized data access increases, making visibility tools a critical infrastructure requirement rather than a luxury.
