NeuralTrust raises $20M to secure the growing swarm of AI agents in the enterprise

NeuralTrust, a cybersecurity platform focused on securing AI agents, has successfully raised $20 million in a seed funding round, marking the largest cybersecurity seed financing raised by a European company to date. The funding announcement was made on June 18, 2026, and the round was led by Alstin Capital, with additional participation from notable investors including VentureFriends, Seaya, Kibo Ventures, Banc Sabadell, EA Ventures Plug and Play Fund, and Finaves. This capital injection is poised to accelerate NeuralTrust's development of its platform, which is designed to identify, secure, and scale AI agents within enterprise environments.

The funding will primarily support engineering efforts, enhance product integration, and facilitate expansion across the European market as enterprises increasingly adopt autonomous AI systems. As organizations transition from experimentation to deploying AI agents as core components of their infrastructure, the need for robust governance and security measures has become critical. According to Gartner, by 2027, 40% of enterprises may demote or decommission autonomous AI agents due to governance issues that only emerge after production incidents. This underscores the urgency for solutions like those offered by NeuralTrust, which aim to address the security challenges associated with managing a growing number of AI agents.

NeuralTrust's platform includes three key products: TrustGate, TrustGuard, and TrustLens. TrustGate serves as an agent gateway, managing all interactions between various AI models and tools, while TrustGuard acts as a runtime security engine that detects and mitigates threats across diverse platforms and endpoints. TrustLens provides posture management by identifying and monitoring the behavior of AI agents within and beyond the security perimeter. The company’s client roster includes major organizations such as AirEuropa, Abanca, Iberia, and Banc Sabadell, with 92% of its customers reporting annual revenues exceeding $1 billion.

The cybersecurity sector, particularly in relation to AI, is experiencing rapid evolution as enterprises grapple with the complexities of securing distributed AI systems. The funding received by NeuralTrust reflects a broader trend where investors are increasingly recognizing the importance of cybersecurity solutions tailored to the unique challenges posed by AI technologies. Independent analysts have acknowledged NeuralTrust as a category leader in this emerging landscape, with Gartner and KuppingerCole highlighting its innovative approach to AI security.

As the market for AI agents continues to expand, the implications of this funding round extend beyond NeuralTrust. With Fortune 500 companies projected to manage over 150,000 AI agents each by 2028, the demand for effective security and governance solutions will only intensify. The investment in NeuralTrust not only positions the company for growth but also signals a critical shift in the cybersecurity landscape, where the integration of AI into enterprise operations necessitates advanced security frameworks capable of keeping pace with technological advancements.
