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
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
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
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
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
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
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
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
