Sentra Raises $150 Million to Secure Enterprise AI Agents

Israeli cybersecurity startup Sentra has secured $150 million in a Series C funding round led by Capital One Ventures, bringing its total capital raised to over $250 million. Founded by veterans of the IDF's Unit 8200, Sentra addresses the growing security risks posed by the rapid proliferation of autonomous AI agents within corporate environments. As businesses deploy thousands of these agents to automate workflows, they often gain access to unclassified or sensitive data. Sentra’s platform provides visibility into these interactions, mapping access permissions and classifying data to ensure that AI agents operate within strict security boundaries. This investment highlights the critical need for governance layers in the AI-native enterprise stack, as companies seek to balance the productivity gains of agentic AI with the necessity of data protection. The company plans to use the funds to expand its workforce and accelerate product development for AI security, including enhanced monitoring of copilots and large language models.
