NeuralTrust vs Solo.io agentgateway: Best AI Gateway for Enterprise Security?

NeuralTrust TrustGate and Solo.io agentgateway are two AI gateways evaluated for enterprise security and platform leaders to manage LLM, MCP, and A2A traffic. TrustGate, developed by a security-focused company, features a first-party Security Engine (TrustGuard) that attaches to every route, providing conversation-level analysis and security inline in the trace tree. It offers a companion posture product, TrustLens, for AI running outside the gateway's path. In contrast, agentgateway, backed by the Linux Foundation and companies like Microsoft and Dell, is Kubernetes-native and emphasizes vendor-neutral governance. It is built in Rust and relies on external integration for content security, offering strong MCP tool governance with fine-grained RBAC via a CEL policy engine. Both gateways are open-source and support multi-protocol routing, but TrustGate comes with 200+ pre-built MCP servers, whereas agentgateway requires customers to source and register their own. The choice between them often hinges on TrustGate's security-first architecture versus agentgateway's Kubernetes-native, infrastructure-first approach.
