What we still need to verify : 4 points in this profile are not yet confirmed against vendor documentation.
- Module names and which components are open-source versus commercial, confirm with vendor
- Supported model providers and protocol coverage, confirm
- Attack library scope in the testing component, confirm
- Self-hosted and Kubernetes deployment specifics, confirm
Treat these points as unconfirmed. They are open items in the catalog's verification queue, and this note stays until each is checked against the vendor's documentation.
What it does
NeuralTrust's approach centers on a gateway. Rather than asking every application team to add a guardrail library, traffic to language models is routed through a proxy that sits between the application and the provider, and policy is applied there: inspection of prompts for injection and jailbreak patterns, masking of sensitive data before it leaves the perimeter, rate and quota controls, and routing or failover between providers. Centralizing at the gateway is the recurring architectural argument in this category, and it holds up well when you have more than a handful of applications to govern.
Around the gateway sit two supporting pieces. An adversarial testing component runs attack scenarios against your own deployed application and reports what got through, which is how you validate that the gateway policy does what you assumed. An observability layer records conversations and surfaces patterns across them, which is the part that catches a slow multi-turn manipulation that no single request would flag.
Where it fits
In the network path in production, deployed and operated by a platform or security team rather than individual application teams. That is the appeal and also the commitment: a gateway is infrastructure, it needs availability planning, and every LLM call in the organization now depends on it. It suits organizations that have already decided to centralize AI access, and fits poorly where each team calls providers directly and will not change that.
Strengths
- Gateway placement enforces policy uniformly, including on applications whose teams would never have added a guardrail themselves.
- Pairing enforcement with adversarial testing lets you verify the policy rather than trusting it.
- Conversation-level observability addresses multi-turn attacks that per-request inspection structurally cannot see.
- Self-hosted deployment keeps prompt content inside your boundary.
Limitations
- A gateway is a new dependency in the critical path of every AI feature, with the latency and availability consequences that implies.
- Younger vendor in a crowded category. Independent evaluation of detection quality is scarce, so test against your own traffic before committing.
- Centralized enforcement only covers traffic that goes through it, so shadow usage and direct provider calls remain outside its view.
Who it suits
A reasonable fit for platform teams consolidating LLM access behind shared infrastructure and wanting one place to write policy. Not the right choice for a single application that needs a guardrail in-process, where a library avoids the extra hop and the operational burden.
