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.

Tempesta FW

• Kernel-Level Performance

  Built directly into Linux TCP/IP stack, processing up to 1.8M HTTP requests per second - 3x faster than Nginx or HAProxy.

• Multi-Layer DDoS Protection

  Integrated protection against volumetric and application-layer DDoS attacks with rate limiting, JavaScript challenges, and adaptive QoS.

• HTTP Tables

  Extends Linux iptables/nftables for application-layer filtering, enabling rules that combine IP addresses with HTTP headers and content.

• Intelligent Load Balancing

  Machine learning-powered load balancing with persistent sessions, weighted round-robin, and rendezvous hashing strategies.

• Web Acceleration

  Built-in caching using Tempesta DB, an ultra-fast in-memory database with NUMA-aware distribution and SIMD optimizations.

• High-Performance TLS

  Tempesta TLS is 40-80% faster than Nginx/OpenSSL with 4x lower latency for TLS handshakes.

• Bot Protection (WebShield)

  Open-source automated bot protection via WebShield — detects and blocks DDoS bots, scrapers, shopping bots, and booking bots using TLS and HTTP fingerprint analysis on access logs stored in ClickHouse.

• Volumetric DDoS Protection

  Upcoming open-source volumetric DDoS protection solution, completing a full L3-L7 DDoS and bot mitigation stack when combined with Tempesta FW's application-layer defences and WebShield.

• Native XDP Integration

  Uses Linux XDP (eXpress Data Path) for early packet dropping, enabling efficient mitigation of volumetric attacks.
