Features Comparison
Barracuda Web Application Firewall
-
Advanced Bot Protection
Machine learning-powered detection distinguishes malicious bots from legitimate traffic and good bots.
-
API Discovery & Protection
Automatically discover APIs and generate security rules from OpenAPI definition files.
-
JSON & XML Security
Deep inspection of JSON payloads and XML protection against schema poisoning attacks.
-
SSL/TLS Offloading
Hardware-accelerated SSL termination with support for modern TLS protocols and cipher suites.
-
DevOps Integration
Full REST API with OpenAPI spec and native support for IaC tools like Terraform and Ansible.
-
Active Directory Integration
Integrate with AD, LDAP, RADIUS for authentication with SAML SSO and two-factor authentication support.
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.
