NeuralTrust Review 2026: AI Agent Security & Gateway Platform

Name: NeuralTrust
Availability: OnlineOnly

NeuralTrust is an AI security platform that secures AI agents, LLMs, and GenAI applications through a high-performance AI gateway processing 20,000+ requests per second, automated red teaming, and guardian agents for autonomous AI monitoring. The split-plane architecture keeps all customer data on-premises or in the customer’s VPC, addressing data sovereignty requirements that cloud-only competitors cannot match.

Founded by Joan Vendrell Farreny (CEO), Alejandro Domingo, and Victor Garcia, NeuralTrust is headquartered in Barcelona with a US office in New York. The company has an official partnership with the European Union and counts major enterprises among its customers, including Banco Sabadell, Iberia, Capgemini, NTT Data, and Air Europa.

NeuralTrust has been recognized in the Gartner Market Guide for AI Gateways (2025) and the Gartner Market Guide for Guardian Agents (2026). KuppingerCole named it a Product and Innovation Leader, and the platform aligns with OWASP, NIST, and Cloud Security Alliance standards. To date, NeuralTrust reports blocking over 15 million attacks, scanning 6.7 million+ models, and analyzing 22 million+ AI interactions.

What is NeuralTrust?

NeuralTrust takes a platform approach to AI security, combining four capabilities under one roof: a high-throughput AI gateway for runtime protection, automated red teaming for pre-deployment testing, guardian agents for agentic AI security, and compliance automation for regulatory requirements.

The architecture uses a split-plane design. The data plane — where all customer content is processed — runs entirely within the customer’s environment (on-premises, VPC, or hybrid). The control plane manages configuration and policy but never touches customer data. This separation addresses data sovereignty requirements without sacrificing centralized management.

The AI gateway handles over 20,000 requests per second per node with sub-100ms latency, making it one of the higher-throughput options in the AI security space. NeuralTrust maintains an open-source presence on GitHub, though the core commercial platform is proprietary.

AI Gateway

High-performance gateway processing 20,000+ requests per second per node at sub-100ms latency. Provides prompt protection, content moderation, sensitive data masking, bot detection, and unified control of GenAI infrastructure.

Guardian Agents

Autonomous security agents that monitor and control AI agent actions in real time. Manage tool and data access through the MCP Gateway, enforce behavioral policies, and detect threats across agent workflows. NeuralTrust is the only AI agent security company officially backed by the European Union.

Automated Red Teaming

Adversarial simulation and defense testing using a catalogue of 150+ attack types. Tests AI models and agents for prompt injection, hallucination, data leakage, and policy violations before deployment.

Runtime security

The AI gateway acts as a Generative Application Firewall, inspecting all traffic between users and AI systems. It provides prompt protection against injection attacks, content moderation with customizable policies, and automatic PII masking before data reaches AI models. Bot detection blocks scrapers and synthetic users that attempt to extract model knowledge or abuse API endpoints.

MCP security

NeuralTrust provides dedicated tools for securing Model Context Protocol communications. The MCP Gateway controls which tools and data sources AI agents can access, while the MCP Scanner tests for vulnerabilities in the CI/CD pipeline. This catches issues before agents reach production with overly permissive tool access.

Model Code Scanner

Beyond runtime protection, the Model Code Scanner examines model-side code for vulnerabilities and security issues. This catches problems in the model layer itself — not just the inputs and outputs — addressing a blind spot that many AI security tools overlook.

Getting Started

Request a demo — Visit neuraltrust.ai and schedule a demonstration. NeuralTrust provides deployment options for cloud, on-premises, VPC, and hybrid environments.

Deploy the data plane — Install the NeuralTrust data plane within your environment. The split-plane architecture ensures all customer content stays within your infrastructure while the control plane handles configuration remotely.

Configure the AI gateway — Set up the gateway as the entry point for AI traffic. Configure prompt protection policies, content moderation rules, sensitive data masking, and bot detection thresholds.

Deploy guardian agents — Activate guardian agents to monitor production AI agents. Configure the MCP Gateway to control tool and data access, and run the MCP Scanner in your CI/CD pipeline.

Run red teaming — Use the automated red teaming module to test AI models and agents against the 150+ attack catalogue before deployment. Schedule ongoing tests to catch new vulnerabilities as models evolve.

When to use NeuralTrust

Ideal for organizations that need high-throughput AI security with data sovereignty guarantees. The split-plane architecture and 20,000+ request-per-second gateway make it a strong fit for enterprises running AI at scale in regulated environments where data cannot leave the organization’s perimeter.

The Guardian Agents concept is especially relevant for organizations deploying autonomous AI agents with MCP server access. Rather than trying to secure agents through static policies alone, NeuralTrust deploys security agents that watch over production AI agents in real time.

The EU headquarters and European Union partnership make NeuralTrust a natural choice for organizations subject to the EU AI Act and GDPR, though the New York office supports North American deployments as well.

Best for

Enterprises running AI at scale that need a high-throughput AI gateway with data sovereignty through split-plane architecture, guardian agents for agentic AI security, and compliance alignment with EU AI Act, OWASP, and NIST frameworks.

Frequently Asked Questions

What is NeuralTrust?

NeuralTrust is an enterprise AI security platform that provides a high-performance AI gateway, automated red teaming, guardian agents, and MCP security for LLMs and AI agents. The platform uses a split-plane architecture where the data plane runs in the customer’s environment, ensuring no customer content is processed externally.

How much does NeuralTrust cost?

NeuralTrust uses enterprise pricing based on the number of protected applications and agents, traffic volume, and deployment model. Pricing is not publicly listed. Contact NeuralTrust for a quote.

What are NeuralTrust Guardian Agents?

Guardian Agents are autonomous security agents that monitor and control the actions of AI agents in real time. They enforce security policies on agent behavior, manage tool and data access through the MCP Gateway, and detect threats across agent workflows — essentially acting as security agents that watch over production AI agents.

How does NeuralTrust compare to Lakera Guard?

NeuralTrust provides a broader platform covering AI gateway, red teaming, agent security, and compliance automation. Lakera Guard focuses on API-level prompt injection defense with sub-50ms latency. NeuralTrust’s gateway handles 20,000+ requests per second per node and includes guardian agents for agentic AI. NeuralTrust is EU-headquartered with split-plane architecture; Lakera (acquired by Check Point) was also European.

Does NeuralTrust support on-premises deployment?

Yes. NeuralTrust uses a split-plane architecture where the data plane runs entirely on-premises, in a customer VPC, or in a hybrid configuration. The control plane operates separately and never processes customer content. All traffic is encrypted with full audit logs available.
