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.

Patchstack

• RapidMitigate (Virtual Patching)

  Automatically deploys targeted mitigation rules within hours of vulnerability disclosure. Rules block only the specific exploit vector, not broad traffic patterns. Claims 74% more exploits blocked compared to leading generic WAFs.

• WordPress Vulnerability Database

  The largest WordPress vulnerability database in the world. 12,000+ active mitigation rules. 4,100+ vulnerabilities disclosed in 2024 alone. Operates as the

• Patchstack Alliance Bug Bounty

  Bug bounty program that pays security researchers to discover vulnerabilities in popular WordPress plugins. Sources vulnerability intelligence from a global community of researchers, ensuring rapid discovery and disclosure.

• Free Monitoring Mode

  The Community plan provides free vulnerability detection and monitoring with no time limit. See which plugins and themes have known vulnerabilities without deploying patches. Useful for awareness and audit.

• PCI-DSS 4.0 Compliance

  Helps WordPress eCommerce sites meet PCI-DSS 4.0 requirement 6.4.2, which requires automated detection and prevention of web-based attacks. Virtual patching specifically addresses this requirement for known vulnerabilities.

• Hardening Recommendations

  Provides security hardening recommendations specific to your WordPress installation. Identifies misconfigured settings, unnecessary file permissions, and security headers.

• Plugin Priority Alerts

  Prioritized alerts based on vulnerability severity and the popularity of affected plugins. Focuses attention on the vulnerabilities most likely to be exploited in the wild.

• Multi-site Management

  Dashboard for managing vulnerability status and virtual patches across multiple WordPress sites. Bulk actions and centralized reporting for agencies and hosting providers.
