SafeLine Web Application Firewall

• Semantic Analysis Engine

  Analyzes the semantic meaning of HTTP requests rather than pattern matching, detecting attack intent even in obfuscated or novel payloads.

• Web Management Dashboard

  Built-in web UI for configuring protected sites, viewing attack logs, managing SSL certificates, and adjusting WAF rules without command-line access.

• One-Command Deployment

  Deploy with a single Docker Compose command. No complex configuration files or dependencies to manage.

• Automatic SSL

  Built-in Let''s Encrypt integration for automatic SSL certificate provisioning and renewal for protected sites.

• Attack Analytics

  Visual dashboard showing attack types, sources, frequency, and trends with detailed request logging for investigation.

• Reverse Proxy Architecture

  Operates as a reverse proxy, sitting in front of web applications to inspect and filter traffic before it reaches the origin server.

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.
