Airlock Microgateway vs Contour

Airlock Microgateway is a Kubernetes-native Web Application and API Protection solution that also serves as an identity-aware proxy. It runs as a container in Kubernetes clusters and is configured through GitOps. The gateway supports Kubernetes Gateway API and is positioned as an upgrade from Ingress NGINX. It validates identities through OIDC, JWT, token exchange or mutual TLS, then applies role- and path-based access control. Protection features include deny rules, CSRF protection, OpenAPI specification enforcement and GraphQL validation against OWASP Top 10 threats. Its Envoy-based reverse proxy supports routing, TLS termination, client certificate authentication and caller IP forwarding. Integrations include Cilium and Istio, and the product is certified for Red Hat OpenShift. Prometheus and Grafana provide monitoring, while logs use ECS format. Deployment can be multi-cloud or hybrid-cloud, but remains self-hosted. Community Edition is free for small environments or local development, with enforced throughput and six-month license validity. The free evaluation license specifies 5 requests per second, at most two replicas per gateway and six-month validity. Premium Edition has no listed price and is intended for enterprise setups.

Contour is a free, self-hosted, open-source Kubernetes ingress controller that provides the control plane for the Envoy edge and service proxy. It supports Kubernetes Ingress v1, its HTTPProxy custom resource and Gateway API. Contour updates ingress configuration dynamically with minimal dropped connections and supports multiple configuration types in clusters used by multiple teams. It can run as a Kubernetes deployment or daemonset, and administrators can delegate access to wildcard certificates. Documented security features include TLS termination, client authorization, rate limiting, JWT verification and IP filtering. Contour and Envoy expose metrics that Prometheus can scrape, and documentation includes guides for cert-manager, Gatekeeper and AWS Network Load Balancer. The project is tested with Kubernetes 1.21 and later and is intended for both cluster administrators and application developers. Community support is available through the project's GitHub page, where users can report issues or ask questions. Contour is a Cloud Native Computing Foundation incubating project; its documentation includes a threat model, a security reporting process and a security fix checklist.
