Proven Security and Authentication
The Ambassador Edge Stack makes securing microservices easy with a comprehensive set of security functionality, including automatic TLS, authentication, rate limiting, WAF integration, and fine-grained access control.
Security and Authentication Features:
- Authentication
- Rate Limiting
- Custom Request Filters
- WAF Integration
- External Filters


Simplified Kubernetes Management with the Ingress Controller
Routing traffic into your Kubernetes cluster requires modern traffic management. The API Gateway contains a modern Kubernetes ingress controller that supports a broad range of protocols including gRPC and gRPC-Web, supports TLS termination, and provides traffic management controls for resource availability.
Ingress Controller Features:
- Kubernetes Integration
- Protocol Support
- Cross-Origin Resource Sharing
- TLS
- Automatic HTTPS
Simplified Traffic Management to Ensure High Availability
Microservices may crash, but your application shouldn’t. The API Gateway includes support for automatic retries, timeouts, circuit breakers, and rate limiting to maximize application availability. In addition to keeping your application available, the API Gateway supports progressive releases with fine-grained traffic management controls.
Traffic Management Features:
- Load Balancing
- Circuit Breaking
- Progressive Delivery

Decentralized, Declarative Workflow
Edge Stack empowers development teams to safely manage their ingress, using the same workflow you already use with Kubernetes.
- Configure using Kubernetes Custom Resource Definitions (CRDs)
- Protocol Support
- Zero downtime reconfiguration
- Integrate with existing GitOps / Kubernetes workflows
