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.

Vercel Firewall

  • Edge-Based Protection

    Firewall runs at the edge across Vercel''s global network, blocking threats before they reach origin servers or serverless functions.

  • DDoS Protection

    Automatic DDoS mitigation at the network and application layer, included on all plans with no configuration required.

  • Rate Limiting

    Configurable rate limits per IP, path, or custom criteria to prevent abuse of APIs and serverless functions.

  • Bot Management

    Detection and management of automated traffic using behavioral signals and challenge pages.

  • Custom Firewall Rules

    Configurable rules based on IP, geography, headers, paths, and request properties via dashboard or vercel.json.

  • Attack Challenge Mode

    Automatic challenge pages for suspicious traffic during active attacks, allowing legitimate users through while blocking bots.

Which One Is Right for You?

The best WAF depends on your specific requirements, infrastructure, and team expertise.

Kong Gateway WAF
