Features Comparison
Blackwall
-
BotGuard Web Protection
Cloud-based bot detection and mitigation for individual websites. Integrates at the web server level without DNS redirect. Behavioral analysis distinguishes legitimate crawlers from malicious bots.
-
GateKeeper Reverse Proxy
Distributed reverse proxy cluster for hosting providers. Sits in front of all hosted websites, providing transparent security without per-site configuration. Scales with hosting provider infrastructure.
-
HTTP/3 QUIC Support
GateKeeper supports HTTP/3 with QUIC protocol, providing better performance on high-latency and lossy connections. Automatic protocol negotiation for browsers that support it.
-
Automatic SSL Management
GateKeeper handles TLS 1.3 certificates automatically. SSL certificates are provisioned and renewed without manual intervention, reducing operational burden for hosting providers managing thousands of domains.
-
WAF with OWASP Top 10
Rule-based WAF protecting against SQL injection, XSS, CSRF, and other OWASP Top 10 attack vectors. Rules updated by the Blackwall security team.
-
Behavioral Bot Detection
Uses behavioral analysis to classify traffic as human, good bot (search engine crawlers), or malicious bot. Goes beyond simple user-agent checking to analyze request patterns and behavior.
-
Rate Limiting
Configurable rate limiting to mitigate brute force attacks, credential stuffing, and application-level DDoS. Can be applied per IP, per endpoint, or globally.
-
CDN Caching Layer
GateKeeper includes a caching layer that absorbs traffic spikes and reduces load on origin servers. Static content is served from the proxy layer, improving response times.
-
Free Monitoring Mode
Observe bot traffic and threat patterns without blocking anything. Useful for evaluation and traffic profiling. Available for both BotGuard and GateKeeper deployments.
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.
Which One Is Right for You?
The best WAF depends on your specific requirements, infrastructure, and team expertise.
Blackwall
- You need: Web hosting providers wanting to bundle bot protection and WAF for their customers. Hosting companies managing large numbers of domains that need automated SSL and transparent security. SMBs wanting bot protection without DNS changes.
- You want to start with a free tier
- You're using: Any web server (Apache, Nginx, LiteSpeed) for BotGuard. Any hosting provider infrastructure for GateKeeper. Compatible with shared hosting, VPS, dedicated servers, and cloud environments.
Kong Gateway WAF
- You need: Organizations already using Kong as their API gateway, Kubernetes-native architectures needing gateway-level WAF, teams wanting unified API management and security in one platform, enterprises with microservices architectures routing all traffic through an API gateway
- You're using: Linux (Ubuntu, RHEL, Debian, Amazon Linux, Alpine), Docker, Kubernetes (via Ingress Controller and Operator), AWS, Azure, GCP, ARM64, macOS (dev)
We recommend evaluating both options with a trial or free tier before committing. Consider your existing infrastructure, team expertise, compliance requirements, and budget.
