Many websites are built using dynamic content management systems such as WordPress, Drupal, Joomla, or TYPO3.
These platforms provide powerful publishing and customization capabilities, but the growing number of plugins and extensions significantly increases the attack surface of the application layer.
As a result, they often become prime targets for security breaches, automated exploitation attempts, and high-volume abusive traffic.
Mass scanning and bot activity can degrade performance, overload backend resources, and impact user experience.
This forces administrators to perform continuous updates, patch management, and security hardening to keep the web engine stable and secure.This feature is no longer available from version 4.50 Service pack 1 or Hotfix 20231110-21
Vitrification is an advanced reverse proxy capability designed to eliminate the operational burden of maintaining dynamic web services.
This feature allows the reverse proxy to crawl the entire destination website and generate a fully static local replica.
Once vitrified, Internet users are served directly from the reverse proxy cache rather than querying the original web server.
This significantly reduces backend load, mitigates exposure to application-layer attacks, and improves response time consistency.
A “vitrified” (frozen and preserved) version of any proxied website can therefore be delivered directly by the reverse proxy without accessing the backend infrastructure.
This approach delivers optimal performance when serving your web pages while significantly strengthening website security.
Because content is delivered as static HTML, application-layer attacks have no impact on the underlying web engine.
Even if the reverse proxy’s local storage becomes corrupted, it will be automatically rebuilt during the next synchronization cycle.
This mechanism ensures resilience, service continuity, and simplified backend maintenance.
It is particularly useful for disaster recovery scenarios, static snapshots, or controlled offline content delivery.
