NeuralTrust, a Barcelona-based AI security firm, has secured a landmark $20 million in seed funding to address the growing risks of autonomous AI agents in enterprises. The round, led by Munich's Alstin Capital, is the largest of its kind for a European cybersecurity company. This investment will fuel the company's expansion as it aims to provide a critical control layer for businesses deploying AI technologies at scale.
The Growing Challenge of AI Agent Governance
As enterprises rapidly adopt AI, they face a significant governance gap, often discovering security issues only after a production incident. Research firm Gartner predicts that by 2027, 40% of companies will be forced to decommission AI agents due to these unforeseen problems. This highlights an urgent need for proactive security measures as AI becomes more integrated into core business operations.
Most large organizations struggle with a lack of visibility, often unaware of how many AI agents are active within their systems. These agents connect to sensitive internal databases and external tools, operating autonomously without adequate oversight. This creates a substantial risk of data leakage or unauthorized actions that security teams are ill-equipped to prevent.
A Unified Platform for AI Security
NeuralTrust addresses this challenge with a comprehensive platform built on three integrated layers. Its TrustGate acts as a central gateway, managing all agent traffic and enforcing security policies at a single point. This foundational component ensures that no interaction, whether with an internal system or an external tool, goes unmonitored.
The platform's security engine, TrustGuard, provides real-time threat detection and prevention across all endpoints, regardless of how an agent was developed. Complementing this is TrustLens, which maps and identifies every agent in the enterprise, tracking its behavior to eliminate blind spots. The company reports that its system currently identifies and stops malicious activity in approximately 1.2% of all interactions.
Strategic Investment and European Expansion
The $20 million funding round was led by Alstin Capital and saw participation from VentureFriends, Seaya, Kibo Ventures, and Banc Sabadell, among others. NeuralTrust has already gained significant traction with major clients like Iberia and AirEuropa, doubling its 2025 annual recurring revenue in the first quarter of 2026 alone. This momentum demonstrates strong market demand for its specialized security solutions.
Alexander Meyer-Scharenberg, a partner at Alstin Capital, noted that AI agents are entering infrastructure faster than security teams can adapt. He praised NeuralTrust for building a genuine control layer that enterprises can implement immediately to manage this new risk. The investment will be used to enhance the product, grow the engineering team, and solidify the company's presence across Europe.
NeuralTrust's position as a European company provides a strategic advantage, particularly as EU AI Act compliance becomes more stringent. Many European government and financial institutions are actively seeking technology partners headquartered outside the United States due to data sovereignty concerns. This unique positioning helps the company cater to a critical segment of the market that prioritizes regional security providers.
This substantial seed funding positions NeuralTrust to become a leader in the emerging field of AI agent security. With plans to deepen its European footprint before expanding into the US market, the company is racing to provide essential governance tools. The investment underscores the critical need for enterprises to secure their AI deployments before a significant security incident forces their hand.
