Eve Security Raises $4.5M Seed Led by Run Ventures for AI Agent Runtime Security

Eve Security Closes $4.5M Seed Round

Austin, Texas-based Eve Security has raised $4.5 million in seed funding led by Run Ventures. The round, dated September 15, 2026, includes participation from LiveOak Ventures, Dreamit Ventures, and Blu Ventures.

This seed round brings the company's total seed funding to $7.5 million, according to the company. Eve Security began go-to-market efforts in January 2026.

What Eve Security Does

Eve Security is building a runtime security and governance platform for enterprise AI agents. As organizations deploy AI agents across business systems, the company's platform is designed to give security teams control over what those agents can do.

The core product is the EveGuard control plane, which provides:

• Real-time visibility into agent activity
• Interrogation of high-risk or anomalous behavior
• Session tainting to track potentially compromised agent sessions
• Deterministic policy enforcement before agents take consequential actions

The platform operates across systems including Databricks, Microsoft Copilot Studio, Amazon Bedrock, Amazon AgentCore, and Glean. These integrations position EveGuard at the point where enterprise AI agents interact with data and tools, aiming to intercept risky actions before they occur.

Leadership

The company is co-founded by CEO Nadav Cornberg.

Why Runtime Security for AI Agents Matters

Enterprise adoption of AI agents has introduced a new class of security and governance challenges. Unlike traditional software, agents can take actions across multiple systems — querying data, invoking tools, and triggering workflows — often with limited human oversight.

Eve Security's approach focuses on the runtime layer, where agent behavior can be observed and constrained. Key elements include:

• Visibility: Security teams need to know what agents are doing in real time.
• Anomaly detection: High-risk or unusual behavior must be surfaced and interrogated.
• Session tainting: Once a session is flagged, it can be tracked and treated with additional scrutiny.
• Deterministic policies: Rather than relying solely on probabilistic detection, the platform enforces explicit rules before consequential actions are executed.

This combination reflects a broader trend in the security market: as AI agents gain autonomy, governance and enforcement mechanisms are becoming a distinct product category.

Market Context

The integrations listed by Eve Security — Databricks, Microsoft Copilot Studio, Amazon Bedrock, Amazon AgentCore, and Glean — represent widely used enterprise data, AI development, and assistant platforms. Supporting these environments suggests the company is targeting enterprises that are already operationalizing AI agents rather than running isolated pilots.

The involvement of Run Ventures as lead, alongside LiveOak Ventures, Dreamit Ventures, and Blu Ventures, provides the company with a mix of venture backing as it scales go-to-market efforts that began in January 2026.

Summary

Eve Security has raised a $4.5 million seed round led by Run Ventures, with participation from LiveOak Ventures, Dreamit Ventures, and Blu Ventures. The Austin-based company builds a runtime security and governance platform for enterprise AI agents, centered on its EveGuard control plane. With $7.5 million in total seed funding and go-to-market efforts underway since January 2026, Eve Security is positioning itself in the emerging category of AI agent security and governance.
