API Gateway

Secure and Control All API Traffic

Route, secure, and observe all API and AI traffic with granular control from a single point reducing engineering overhead. Handle REST, GraphQL, gRPC, event-driven APIs, and AI/MCP traffic while extending control to third-party and hybrid environments.

Manage Every Ingress and Egress API Interaction

API-Gateway

Why it matters

APIs power everything and ungoverned API traffic leads to security risks, performance issues,
and compliance gaps. With WSO2, you can:

Unified traffic control

Govern incoming and outgoing API traffic in real time

Multi-protocol gateway

Secure REST, GraphQL, gRPC, and AsyncAPIs through one gateway

Consistent policies everywhere

Enforce consistent policies, SLAs, and observability across federated environments

AI and agent-aware control

Extend gateway capabilities to AI and agent traffic using WSO2’s AI Gateway

WSO2 API Gateway gives you a single, consistent way to control all
traffic—north-south, east-west, ingress, and egress—across any deployment model.

Key capabilities

Unified traffic management

Unified traffic management

Secure, shape, and monitor every incoming (ingress) and outgoing (egress) request from a single architecture. Manage APIs you expose to consumers, and also regulate how your services call external or third-party APIs.

Highlights
  • Centralized policy enforcement for both inbound and outbound APIs
  • Rate limiting, caching, and quota management
  • Authentication and authorization with OAuth2, JWT, and mTLS
  • Request and response mediation, transformation, and schema validation
Multi-protocol support

Multi-protocol support

Deliver seamless traffic management across all modern API styles and interaction patterns. This flexibility ensures the gateway aligns with any architecture—standard APIs, microservices, or event streams.

Supports
  • REST and GraphQL for synchronous, request-response APIs
  • gRPC for high-performance microservice communication
  • WebSocket, Server-Sent Events (SSE), and Webhooks for real-time, event-driven communication
  • Kafka for event streaming and asynchronous message processing
Multiple gateway deployments

Multiple gateway deployments

WSO2’s modular architecture lets you choose the gateway that fits your environment—without sacrificing control. They can be centrally managed through one control plane, enabling governance and analytics across distributed environments.

  • Universal Gateway: Centralized deployments across on-premises or hybrid environments
  • Kubernetes Gateway: Kubernetes-native API management for microservices and cloud workloads
  • Immutable Gateway: Air-gapped, regulated, or self-contained environments requiring locked-down deployments
  • Event Gateway: Event-driven APIs using WebSocket, SSE, Webhooks, and Kafka
  • AI: Managing LLM traffic, applying AI guardrails, and exposing APIs as MCP tools for AI agents
Security, guardrails, and observability

Security, guardrails, and observability

Protect APIs at every layer. Apply authentication, authorization, rate limits, and data masking consistently across all gateways. Monitor real-time performance and apply AI-driven guardrails for sensitive or AI-generated content.

Includes
  • Threat protection and validation policies
  • Rate-limiting and throttling templates
  • PII masking, prompt filtering, and semantic validation for AI calls
  • Full analytics integration with Moesif
Federated gateway control

Federated gateway control

Manage multiple gateways, clusters, and environments through a single control plane. Automatically discover APIs from third-party gateways (AWS, Azure, Kong, Envoy) and onboard them into your governance model.

Benefits
  • Eliminate operational silos
  • Apply uniform policies and visibility across all gateways
  • Lower complexity while maintaining deployment flexibility
Developer-friendly and extensible

Developer-friendly and extensible

WSO2 API Gateway is fully programmable and customizable. Define routes, transformations, and policies as code. Extend functionality using built-in interceptors, custom mediators, and plug-ins.

Integration Ready
  • GitOps and CI/CD workflows
  • Policy as Code with OPA

Benefits at a glance

Eliminate fragmented gateway management

Unified control plane with federation

Improve performance and reduce latency

Distributed throttling, caching, and edge deployments

Enforce consistent policies across clouds

Centralized governance and observability

Support every API style and protocol

Support for open standards

Gain full visibility into API and AI traffic

Integrated analytics and Moesif dashboards

Avoid vendor lock-in

Open-source, standard-based, and extensible

WSO2 API Gateway is your traffic control center.
Unify ingress, egress, and AI traffic management across any cloud or edge, enforce policies globally,
and deploy anywhere without losing control.
