SOC 2. Trusted by Duck Creek Payments. ## Why Teams Move Away from Envoy Proxy ### Infrastructure Proxy, Not API Management Envoy is a high-performance L7 proxy. Developer portal, API key lifecycle, monetization, and AI Gateway are not built in. ### Control Plane Required Production deployments require a control plane like Istio or Envoy Gateway plus Kubernetes infrastructure to operate. ### Steep Configuration Complexity Protobuf-based configuration and the xDS API have a steep learning curve, even for experienced infrastructure engineers. ## About Envoy Proxy Envoy Proxy is a CNCF-graduated, high-performance C++ L7 proxy originally built at Lyft. It serves as the data plane for service meshes like Istio and powers projects like Envoy Gateway and kgateway. Envoy excels at low-level traffic management with advanced load balancing, gRPC-native support, and dynamic configuration via its xDS API — making it the standard for cloud-native service mesh architectures. For internal east-west service mesh, Envoy is the industry standard; for external-facing API products with developer portal and monetization needs, Zuplo provides the platform layer. ## Why Choose Zuplo Zuplo is focused on external-facing API products. Edge-native architecture, TypeScript programmability, GitOps workflows, and an integrated AI Gateway with MCP support — backed by SOC 2 Type II, managed dedicated deployment, and named regulated customers across insurance, payments, and infrastructure. ## Feature Comparison ### Compliance and Audit Readiness _First-class managed compliance vs. compliance dependent on customer environment._ - **Zuplo** — SOC 2 Type II audited annually, third-party penetration test reports under NDA, audit logs, GDPR-aligned data processing. - **Envoy Proxy** — Compliance posture inherited from customer-operated environment. ### Enterprise Identity (SSO + RBAC) _Direct SAML/SCIM with project-level RBAC vs. customer-managed filter-based identity._ - **Zuplo** — SAML SSO, SCIM provisioning, and RBAC across organizations, projects, and environments. - **Envoy Proxy** — Customer-managed identity through Kubernetes RBAC and configured auth filters. ### Managed Dedicated Deployment _Managed dedicated across major clouds vs. customer-managed Kubernetes plus control plane._ - **Zuplo** — Single-tenant managed deployment on AWS, Azure, GCP, Akamai, or any major cloud with up to a 30-minute response SLA. Self-hosted on Kubernetes also supported. - **Envoy Proxy** — Self-hosted in customer Kubernetes with control plane management. ### AI Gateway and MCP Support _Managed AI Gateway and MCP Gateway vs. self-operated open-source Envoy AI Gateway._ - **Zuplo** — Integrated AI Gateway with multi-provider routing, semantic caching, prompt injection protection, budget and token controls. Dedicated MCP Gateway product. - **Envoy Proxy** — Envoy AI Gateway (separate open-source project, GA June 2026) provides LLM routing, token rate limiting, provider failover, and MCP routing — but you operate it yourself, with no managed control plane, prompt injection protection, or monetization. ### Full API Management _Unified API management platform vs. infrastructure proxy plus external API tooling._ - **Zuplo** — Complete API lifecycle: developer portal, API keys, programmable rate limiting, analytics, monetization, AI Gateway. - **Envoy Proxy** — High-performance L7 proxy focused on traffic routing, load balancing, observability. API management features require external services. ### Developer Portal _Built-in developer portal vs. no developer portal._ - **Zuplo** — Auto-generated from OpenAPI spec with self-serve API key management and interactive docs. - **Envoy Proxy** — No built-in developer portal — requires external tooling. ### API Key Management _Built-in API key lifecycle vs. custom implementation required._ - **Zuplo** — Full lifecycle with hashed storage, expiration, metadata, RBAC scopes, self-serve portal. - **Envoy Proxy** — Not included — requires external identity provider or custom implementation. ### Operational Simplicity _Zero-ops managed gateway vs. Kubernetes + control plane operations._ - **Zuplo** — Fully managed and serverless across 300+ edge locations. - **Envoy Proxy** — Self-hosted in Kubernetes plus control plane (Istio, Envoy Gateway, kgateway) plus operational expertise. ### Configuration Approach _TypeScript and OpenAPI vs. protobuf and xDS API._ - **Zuplo** — TypeScript and JSON — familiar to any developer. OpenAPI-native config. - **Envoy Proxy** — Protobuf configs and xDS API. Steep learning curve for API teams. ### Rate Limiting _Programmable distributed rate limiting vs. external Redis-backed rate limit service._ - **Zuplo** — Programmable per-user, per-key, or per-API rate limits with TypeScript logic. - **Envoy Proxy** — Local per-instance limits via filter config; distributed rate limiting requires an external Redis-backed rate limit service. ### gRPC Support _Both support gRPC; Envoy has deeper protocol-level capabilities._ - **Zuplo** — HTTP/2 and gRPC proxying supported. - **Envoy Proxy** — Best-in-class gRPC native support including transcoding and Web bridging. ## FAQ **How does Zuplo handle SOC 2, SSO, and audit logs for regulated customers?** Zuplo is SOC 2 Type II audited annually with reports available under NDA. Enterprise includes SAML SSO, SCIM provisioning, RBAC across organizations and projects, and audit logs across the control plane. **Which enterprises run production workloads on Zuplo?** Zuplo runs production API traffic for regulated and high-volume enterprises including Duck Creek Payments (insurance and payments), Finsolutia (mortgage servicing across Europe), Blockdaemon (blockchain infrastructure serving Goldman Sachs, Microsoft, J.P. Morgan), AccuWeather, and Yext. **Is Zuplo a replacement for Envoy as a service mesh?** No. Envoy is optimized for internal east-west traffic in microservice architectures. Zuplo is designed for north-south external API traffic — the external-facing APIs your consumers interact with. They serve different purposes and many teams use both. **Does Zuplo require Kubernetes?** No. Zuplo is fully managed and serverless. Self-hosted on Kubernetes is available when full data residency and operational ownership are required. **Does Zuplo support gRPC like Envoy?** Envoy has first-class gRPC support including gRPC-JSON transcoding, gRPC-Web bridging, and HTTP/3. Zuplo focuses on HTTP-based REST and JSON APIs with WebSocket support and gRPC proxying. If gRPC is your primary protocol with deep transcoding requirements, Envoy is the stronger choice. Many teams use Envoy for gRPC-heavy internal services and Zuplo for external REST APIs. **How does Zuplo's AI Gateway compare to Envoy?** The Envoy AI Gateway (a separate open-source project that reached v1.0 GA in June 2026) adds LLM provider routing, token-aware rate limiting, provider failover, and MCP routing on top of Envoy Gateway — but you deploy and operate it yourself, and prompt injection protection and semantic caching are not built in. Zuplo offers a fully managed AI Gateway with multi-provider model routing, semantic caching, prompt injection protection, budget and token controls, and a dedicated MCP Gateway product. **How does Zuplo's TCO compare to Envoy?** For external API management, Zuplo Enterprise replaces Kubernetes infrastructure plus control-plane operations plus the engineering cost of building developer portal, API key lifecycle, monetization, and AI Gateway on top of Envoy filters with a single managed contract that includes SOC 2 controls, SSO, and audit logs.
