NeuralTrust: sovereignty score and 8 European alternatives

NeuralTrust is a security platform for AI agents. TrustGate is a gateway that connects agents to models and tools, TrustGuard provides runtime protection for prompts, responses and tool calls, TrustLens discovers and governs agents, and TrustTest performs adversarial red teaming of models. Central guardrail policies cover prompt and content filtering, data loss prevention and tool-use permissions, and audit logs integrate with the customer's SIEM. According to the vendor, it can be deployed as SaaS, on-premises, in a customer VPC, or a combination.

NeuralTrust is based in Barcelona, Spain, and also lists offices in New York and London. It uses a split-plane architecture: the data plane runs in the customer's VPC or on-premises, while the control plane can run in NeuralTrust's cloud or in the customer's own. A European organisation can therefore keep prompts and responses inside its own environment. The vendor's website does not describe an open-source edition, and it does not name hosting regions for its cloud control plane.

Why digital sovereignty matters with NeuralTrust

NeuralTrust is headquartered in ES and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so NeuralTrust scores best on data residency.

NeuralTrust is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs NeuralTrust together with your other vendors and gives a total score, a heatmap and the main risk drivers.
