The following flow diagram shows the layers, security architecture, and processing of requests between web visitors and the infrastructure in MODX Cloud.
Note: Cloud Edge is an optional add-on per hostname that gives site owners control over allow and block lists, powered by Cloudflare Enterprise. It is highly recommended for any production website; cost starts at $15/month including the first hostname + $10 for each additional hostname. The local MODX Cloud firewall aggregates signals across the entire MODX Cloud networks and is designed to block agressive bots and scrapers plus attempts to exploit known security vulnerabilities (especially for WP 🤨).
