NeuralTrust, a cybersecurity company focused on securing enterprise AI agents, has raised $20 million in seed financing as organizations accelerate the deployment of autonomous AI systems across business operations.
The funding round, which the company says is the largest cybersecurity seed investment raised by a European Union-based company to date, was led by Alstin Capital. Additional participants included VentureFriends, Seaya, Kibo Ventures, Banc Sabadell, EA Ventures Plug and Play Fund and Finaves, the venture capital fund of IESE Business School. NeuralTrust also received support from the European Innovation Council and Spain’s State Research Agency (AEI).
The new capital will be used to expand engineering resources, deepen integration across the company’s security platform and accelerate growth across European markets as enterprises move AI agents from pilot projects into production environments.
The investment comes amid growing concerns over the governance and security challenges associated with autonomous AI systems. As companies increasingly deploy AI agents to automate workflows, customer interactions and business processes, cybersecurity and compliance risks have emerged as key barriers to adoption.
According to Gartner, 40% of enterprises are expected to demote or decommission autonomous AI agents by 2027 due to governance shortcomings discovered after deployment. At the same time, large organizations are expected to dramatically increase their use of AI agents, with Fortune 500 companies projected to operate more than 150,000 agents each by 2028.
NeuralTrust aims to address that challenge by providing a unified security and governance layer for AI agents operating across multiple platforms, applications and endpoints. The company’s platform is designed to help enterprises identify, monitor and secure AI systems regardless of where or how they are deployed.
“AI agents are now part of enterprise operations, but the controls protecting them are still catching up,” said Joan Vendrell, co-founder and CEO of NeuralTrust. “This round allows us to keep building the infrastructure layer that makes AI adoption measurable, governable, and safe.”
The company’s platform consists of three core products. TrustGate functions as an agent gateway that manages and controls interactions between large language models, external tools and enterprise systems. TrustGuard provides runtime security designed to detect and prevent threats affecting AI agents across different environments. TrustLens delivers posture management capabilities that help organizations identify AI agents and monitor their behavior both inside and outside established security perimeters.
Together, the platform is intended to give enterprises a centralized framework for managing AI security at scale as the number of deployed agents grows.
NeuralTrust has already attracted a customer base that includes Air Europa, Iberia, Abanca and Banc Sabadell, along with other banking, aviation, energy and government organizations. The company reports that 92% of its customers generate more than $1 billion in annual revenue, reflecting strong adoption among large enterprises. Approximately 80% of its customer base is located in Europe, with the remaining 20% operating internationally.
The company has also gained recognition from several industry analysts as the emerging AI security market continues to take shape. Gartner has identified NeuralTrust as a Representative Vendor in two market guides, while KuppingerCole named the company a leader in its 2025 Leadership Compass for Generative AI Defense. MarketsandMarkets also recognized NeuralTrust as a leader in its 2026 Agentic AI Security Quadrant.
The financing reflects growing investor interest in technologies designed to secure artificial intelligence systems as enterprises increasingly integrate AI into critical business operations. While spending on AI infrastructure continues to rise, governance, compliance and cybersecurity concerns remain among the top challenges facing large organizations.
By focusing specifically on AI agent security, NeuralTrust is positioning itself within a rapidly emerging category that many industry observers expect to become a foundational component of enterprise AI deployments. The company plans to use the funding to strengthen its technology platform and expand its presence as demand for AI governance and security solutions continues to accelerate.
Founded in Europe, NeuralTrust describes its mission as helping enterprises identify, secure and govern AI agents operating across increasingly complex digital environments, providing the controls necessary to support large-scale AI adoption while reducing operational and cybersecurity risk.
