Features Comparison
Kong Gateway WAF
-
Gateway-Embedded WAF
WAF runs as a plugin inside the Kong Gateway process, inspecting API traffic at the same layer where routing, authentication, and rate limiting occur. No separate WAF appliance or additional proxy hop needed.
-
OWASP Top 10 Protection
Built-in protection against common web application attacks including SQL injection, cross-site scripting, command injection, and path traversal at the API gateway layer.
-
Plugin Ecosystem
Over 100 plugins for security, traffic control, authentication, and observability. WAF works alongside bot detection, IP restriction, CORS, ACL, and rate limiting plugins in a configurable execution chain.
-
Third-Party WAF Integrations
Open plugin architecture supports third-party WAF engines including open-appsec (ML-driven detection) and Wallarm (API security). Teams can choose the WAF engine that fits their threat model.
-
Kubernetes-Native Deployment
Kong Ingress Controller and Kong Kubernetes Operator provide native Kubernetes integration. WAF policies can be managed declaratively through Kubernetes CRDs alongside gateway configuration.
-
Hybrid Mode
Cloud-managed control plane with self-hosted data planes. WAF policies are centrally managed and distributed to data planes running in any environment, including air-gapped networks.
-
AI Gateway
Dedicated AI gateway capabilities including LLM proxy, token-based rate limiting, semantic caching, PII sanitization, prompt guardrails, and MCP server proxy. WAF protects AI endpoints alongside traditional APIs.
-
Declarative Configuration
Gateway and WAF configuration can be managed as code through declarative YAML/JSON, enabling GitOps workflows and CI/CD pipeline integration for security policy changes.
-
Advanced Rate Limiting
Enterprise-grade rate limiting with sliding window counters, consumer groups, and cluster-wide synchronization. Works in conjunction with WAF to prevent both application-layer attacks and abuse.
Prophaze Web Application Firewall
-
AI Behavioral Detection
Machine learning-based threat detection identifies attacks through behavioral analysis, not just signatures.
-
Kubernetes-Native WAF
Built on Kubernetes platform for seamless integration with containerized microservices deployments.
-
Zero-Configuration API Protection
Adaptive profiling automatically learns API behavior and protects endpoints without manual rule configuration.
-
Bot Mitigation
Detect and block malicious bots while allowing legitimate automation and search engine crawlers.
-
DDoS Protection
Layer 3-7 DDoS mitigation with automatic traffic scrubbing and rate limiting.
-
Virtual Patching
Immediate protection against known vulnerabilities without requiring application code changes.
