About Eve Security
Eve Security provides a runtime security layer that gives organizations observability, governance and real-time controls over AI agents, letting teams intervene when an agent misbehaves. It raised $4.5 million in September 2026, led by Run Ventures, extending its total seed round to $7.5 million.
What is Eve Security?
What is Eve Security?
Eve Security is a runtime security startup focused on AI agents. Its platform gives organizations the observability, governance and controls needed to deploy agents safely, identifies high-risk or anomalous activity, and lets teams step in before an agent can interfere with critical systems.
The company argues that traditional security tools built around human users, identities, endpoints and infrastructure cannot tell whether a series of seemingly legitimate agent actions is normal execution or groundwork for something malicious. Co-founder and CEO Nadav Cornberg says securing agents requires understanding what they are doing and why, and being able to intervene while it happens, rather than only defining rules in advance.
Eve turns security policies into a deterministic enforcement layer, where policy-matched agent requests and actions are evaluated and enforced in real time. It adds discovery, enforcement and automated remediation across Databricks, Microsoft Copilot Studio, Amazon AgentCore, Amazon Bedrock and Glean environments. Session tainting restricts what an agent can do based on its prior actions and exposure to sensitive data. The platform also enriches observability with context from identity providers, data platforms such as Databricks and Snowflake, and data loss prevention systems.
Eve Security launched in January 2026.
