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.

Coraza Web Application Firewall

  • ModSecurity Compatibility

    Full compatibility with ModSecurity SecLang rule language. Existing ModSecurity rules and rule sets work without modification.

  • OWASP CRS Support

    Native support for the OWASP Core Rule Set, providing protection against SQL injection, XSS, RCE, and other OWASP Top 10 threats.

  • Go Native

    Pure Go implementation with no C dependencies. Embeddable as a library, usable as middleware, or deployable as a plugin for modern proxies.

  • Proxy Plugins

    Official plugins for Caddy (coraza-caddy), Traefik, and HAProxy allow adding WAF protection with minimal configuration.

  • Kubernetes Ready

    Lightweight enough to run as a sidecar or embedded in ingress controllers. Works with any Go-based K8s tooling.

  • Audit Logging

    Detailed audit logging of blocked and flagged requests for security analysis and compliance reporting.
