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.

NSFOCUS Web Application Firewall

• Semantic Analysis Engine

  Uses semantic analysis to understand and detect complex web attacks beyond simple pattern matching, reducing false positives and catching evasion attempts.

• API Security

  Comprehensive API asset management with real-time shadow API discovery, parameter oversight, and sensitive data identification across regional deployments.

• Dynamic Bot Traffic Protection

  Distinguishes between human and machine traffic using dynamic tokens to prevent replay attacks, unauthorized access, and information scraping.

• Virtual Patching

  Virtually patch vulnerabilities in web applications without requiring the application to be updated, providing immediate protection for known CVEs.

• Threat Intelligence Integration

  Deep integration with NSFOCUS Threat Intelligence (NTI) for real-time threat feeds and actionable intelligence to protect against emerging attacks.

• Layered Detection System

  Multi-layered defense with traffic pre-filtering, customizable detection criteria, and sophisticated logical combinations for precise rule enforcement.
