Features Comparison

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.

SonicWall Web Application Firewall

  • 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.
