Eve Security Raises $3 Million Seed Introduces Industry-First Agent-in-the-Loop along with Data and Intent Driven Policy Enforcement for Agentic AI Security

Eve Security's combination of Agent-in-the-Loop and intent-based policy enforcement delivers the industry's deepest observability and security for Agentic activity

AUSTIN, Texas, Sept. 16, 2025 /PRNewswire/ -- Eve Security today announced its $3 million seed round and the availability of EveGuard, an agentic AI observability and policy enforcement platform that ensures the security of AI agents interacting with a company's most crucial business systems. The seed round is led by LiveOak Ventures with participation from Tau Ventures.

Eve Security's EveGuard introduces the industry's first Agent-in-the-Loop (AITL) – Eve. Eve detects anomalies, clusters requests, assesses risks and interrogates other agents so that CISOs and department heads don't have to. While Human-in-the-Loop is garnering attention, an Agent-in-the-Loop that can quantify risk and assign tasks to agents and humans will dramatically impact the effectiveness of Agentic AI security. Eve Security's AITL, Eve, can observe agents, agent interactions with each other, with humans and with critical business systems and take necessary action. Eve behaves predictably and consistently under the same conditions, allowing humans to oversee decisions with reliability and accountability, and follows predictable, rule-based logic that produces the same result every time when given the same input.

EveGuard also includes Intent- and Data-Based Policy Enforcement to address the challenges in English-language-based policies that create blind spots such as translation and cultural nuances. Eve Security's platform is able to define and enforce policies that understand intent and data included in agentic requests. These new capabilities are not available in existing security products.

"Agentic AI is already inside the enterprise, whether CISOs and other leaders approve it or not. Shadow AI agents are making decisions, moving data, and creating vulnerabilities that today's security tools simply can't see. Right now, most security leaders are flying blind," said Creighton Hicks, Partner at LiveOak Ventures. "Eve Security enables security teams to gain visibility and control over the known and unknown agentic AI running in their enterprise."

"CISOs today are faced with both great opportunity and great responsibility," said Nadav Cornberg, co-founder and CEO, Eve Security. "We help them to innovate with AI with confidence and trust that their organization's crown jewels – the data and systems that matter most to their business – are protected. Our implementation and combination of observability, policy and AITL allows CISOs and department heads to trust the activity of their AI agents. Our support for API, MCP and A2A protocols allows us to go deeper than competitors to observe, detect and react to security concerns quickly."

Moore's Law, the principle that the speed and capability of computers can be expected to double every two years, doesn't account for AI. Based on collective industry reports, Agentic AI is doubling in capability and adoption every twelve months, compressing decades of digital transformation into just a few years. What was on the tip of everyone's tongue less than a year ago is deployed in enterprises around the world. This provides both great promise and great risk for CISOs. Agentic AI and its pace of development has increased both the attack surface and attack type for security breaches. From "vibe-hacking," as just reported by Anthropic, to data exfiltration, malicious actors are already exploiting the very autonomy that makes these systems so powerful. The risks are escalating faster than traditional security tools can adapt, creating a widening gap between innovation and protection. Eve Security combines the industry's first AITL and intent-based policy enforcement to deliver the deepest observability of agentic AI activity with critical business systems. It also offers a frictionless deployment that delivers value and the safeguards enterprises urgently need to deploy and run AI agents with confidence – on day one.

"Eve Security is kind of like the security seatbelt for AI's self-driving era," said Chris Aniszczyk, Eve Security advisor, CTO at the Cloud Native Computing Foundation. "Everyone wants to go fast and keep pace with the rate of change. With its focus on business critical systems and its Agent-in-the-Loop method, Eve Security is the best way to do it."

EveGuard includes: 

• Agent-in-the-Loop (AITL): The Eve Security AITL, Eve, identifies anomalies, assesses risk, clusters requests, interrogates agents and acts as a security analyst to take action. Eve Security manages all the agentic activity between an AI agent and an organization's most critical business systems – what the company calls the 'crown jewels,' systems that include financials, human resources, and sales systems. This ensures consistency, compliance and auditability, which are critical to industries like finance, healthcare, and security.
• In-Depth Observability: Eve Security supports Model Context Protocol (MCP) and Agent-to-Agent (A2A) protocols to securely access external tools, APIs, data sources and more. These protocols enable deep insights into AI agent interactions and agent-to-agent coordination and delegation chains.
• Policy Enforcement: English-language-based policies create security blind spots in agentic AI due to issues with translation and cultural nuances. Eve Security's platform is able to define and enforce policies that understand intent and data included in agentic requests. These are new capabilities not available in existing security products.
• Frictionless Deployments: Customers can deploy Eve Security without new infrastructure or even a plug-in to get started, enabling net value on day one.

Eve Security is founded by CEO Nadav Cornberg, CRO Sharon Eilon and CTO Amit Eliav. Their depth of expertise in cybersecurity, AI and business growth makes them poised to solve one of the most pressing enterprise technology challenges of our time. The $3 million seed round will help the team continue to develop product features and its go-to-market (GTM) strategy.
