Deep Packet Inspection
Layer 7 traffic analysis using regularly updated threat signature databases to detect and block application-layer attacks.
-
Anomaly Detection
Baselines normal application behavior and identifies suspicious deviations that may indicate attacks.
-
Application Profiling
Learns application structure and enforces positive security model based on expected input patterns.
-
SSL/TLS Offloading
Handles SSL/TLS termination and inspection, reducing load on backend servers while enabling encrypted traffic analysis.
-
Bot Protection
Identifies and blocks malicious bots while allowing legitimate crawlers through configurable policies.
-
PCI DSS Reporting
Built-in compliance reporting for PCI DSS requirements related to web application security.
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.
-
