NeuralTrust vs Portkey: Best for Enterprise AI Security?

NeuralTrust TrustGate and Portkey are two AI gateways evaluated for enterprise security and platform leaders as control layers for LLM, MCP, and agent traffic. TrustGate, developed by NeuralTrust, emphasizes security with a first-party Security Engine (TrustGuard) attached to every Route, offering unified multi-protocol trace trees and a separate posture product (TrustLens) for AI discovery outside the gateway. It is designed by an independent AI security company, ensuring an independent roadmap. Portkey, recently acquired by Palo Alto Networks, is known for its broad model coverage and mature observability, providing reliability features like fallbacks and load balancing, but its runtime security capabilities are being integrated into Palo Alto's Prisma AIRS platform. Both gateways are open-source, self-hostable with commercial tiers, and focus on routing, policy, and observability, yet differ in their security models and organizational independence, making TrustGate suitable for security-focused buyers desiring independence and Portkey for teams seeking extensive model coverage and integration with Palo Alto's ecosystem.
