Features Comparison

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.

ThreatX by A10 Networks

  • Hacker Mind Risk Engine

    Adaptive risk scoring that tracks entities across sessions and attack vectors, correlating probing behavior over time instead of judging requests one at a time.

  • Managed SOC

    24/7 analysts included in the subscription who tune policies, hunt threats, apply virtual patches, and hand-validate alerts before they reach your team.

  • API Protection

    Automatic API cataloging with behavioral analysis and fingerprinting to catch abuse, enumeration, and business logic attacks against north-south API traffic.

  • Bot Management

    Blocks credential stuffing, scraping, and scalping by profiling the attacker rather than matching a static bot signature list.

  • Layer 7 DDoS Defense

    Entity and transaction based tracking that absorbs multi-vector application-layer floods without blanket rate limits on real users.

  • Sensitive Data Redaction

    Automatic redaction of credentials, tokens, card numbers, and SSN patterns in captured traffic, with a 90-day retention policy.
