Nivoli Edge

• Full-Page Edge Caching

  Caches whole pages on the Cloudflare node nearest each visitor, tagged with Surrogate-Keys so one post save purges only the affected pages via stale-while-revalidate.

• Asset URL Versioning

  Gives stylesheets, scripts and fonts addresses that change on purge, so browsers pick up updated files immediately instead of serving stale ones for up to a week.

• Edge Image Optimization

  Rewrites images at the WordPress filter boundary and transforms them on the fly via Cloudflare Image Resizing: right-sized per device, WebP or AVIF per browser.

• Origin Shield

  When the origin errors or stops responding, serves the last good cached copy for up to 7 days, with email alerts when the shield engages and when the server recovers.

• Pre-PHP Security Shields

  Seven shields enforced at the edge before WordPress boots: stray-.php 404s, wp-admin IP lock, login rate limiting, AI-crawler blocking, login country lock, XML-RPC 410, security headers pack.

• Cookieless Audience Analytics

  Measures pageviews, countries, referrers and devices at the edge, no JavaScript snippet, no cookies and no consent banner; bots counted separately.

• Edge URL Rules

  Answers dead routes with cached 410s and maps redirects from the edge with per-rule fired counts; one-click block from the error log.

• Surgical Purge

  Dispatches purge requests non-blocking by Surrogate-Key tags on save, delete and comment events; purge triggers can be locked to your own IPs.

• Coverage Audit & Repair

  Weekly re-run measures the optimized share and emails on regression; the runtime misses log groups uncovered images into one-click rules; fake-image scan repairs HTML-disguised-as-JPG files.

• Broken & Heavy Image Tools

  404 inbox from real edge failures, where-used lookups with edit links, a heaviest-images list with one-click Tinify shrink, and a scan for images that never load.

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.
