Eve Security Launches EveGuard, Raises $3 Million to Police Enterprise AI Agents

The Austin startup says its Agent-in-the-Loop tech gives security teams visibility into unsanctioned AI behavior.

Overview

  • Eve Security closed a $3 million seed round led by LiveOak Ventures with participation from Tau Ventures to accelerate product development and go-to-market.
  • The company released EveGuard, a commercially available platform featuring an Agent-in-the-Loop called Eve that detects anomalies, clusters requests, assesses risk, interrogates agents, and can take action or escalate.
  • EveGuard supports API access plus Model Context Protocol (MCP) and Agent-to-Agent (A2A) standards to observe tool use, delegation chains, and multi-agent coordination.
  • Intent- and data-based policy enforcement aims to reduce blind spots in traditional English-language rules, improving control across multilingual and culturally varied environments.
  • An on-customer component integrates with SIEM and existing security tools to approve known agents, sanitize outputs in real time to blunt prompt-injection attacks, and enforce access policies.
