NeuralTrust, a Barcelona-based enterprise platform for securing AI agents, has raised $20M in seed funding led by Alstin Capital. The company provides centralized visibility and control over AI agents through vulnerability detection, runtime protection, posture management, and red teaming. The capital will accelerate engineering, product integration, and European expansion.
Agent Sprawl Outpaces Security Controls
The timing aligns with rapid enterprise adoption of autonomous agents. Noma Security raised $100M Series B in July 2025, while Zenity secured $38M Series B in October 2024. NeuralTrust differentiates through a full-stack European platform with data sovereignty features tailored for regulated sectors.
Governance Gaps Threaten Agent Deployments
Gartner forecasts that by 2027, 40% of enterprises will demote or decommission autonomous AI agents due to governance gaps. Fortune 500 companies are projected to operate more than 150,000 agents each by 2028, yet only 13% feel prepared. NeuralTrust reports blocking 3M+ attacks and preventing $43M in potential losses across 1,000+ monitored applications.
Full-Stack Platform Targets Agent Lifecycle
NeuralTrust offers four integrated products: TrustGate for secure gateways, TrustGuard for runtime attack prevention, TrustLens for discovering shadow AI risks, and TrustTest for automated red teaming with a 150+ attack catalog. This breadth contrasts with point solutions from competitors focused on narrower LLM or model security.
"By 2028, Fortune 500 companies will run more than 150,000 agents each. Only 13% feel ready to manage them."
European Investors Signal Regulatory Focus
Alstin Capital led the round with participation from Seaya, Kibo Ventures, VentureFriends, and corporate investors including Banc Sabadell. The syndicate reflects conviction in EU data sovereignty needs as the AI Act enforcement increases, positioning NeuralTrust as a non-US alternative for banks and government agencies.
Agentic AI Security Market Accelerates
The agentic AI security segment is projected to grow from $1.65B–$2.43B to between $9.6B and $13.5B by 2031-32. Broader AI security platforms are expected to reach $31.2B by 2036. Consolidation activity, including Palo Alto Networks' acquisition of Protect AI, underscores that AI agent protection is shifting from optional to essential infrastructure.
Expansion Plans Target Key Markets
With deployments already serving major European banks and airlines, NeuralTrust is hiring founding account executives across Germany and the UK while opening additional offices. The open-source TrustGate component supports rapid adoption as the company scales into regulated verticals.
