Drupal Maintenance: Your Open-Source CMS in Expert Hands

Drupal follows a clear versioning scheme: each major version (Drupal 9, 10, 11) is actively maintained until the community sets an end-of-life date. Once end-of-life is reached, security patches stop and community support ends. For running websites this means: migration to the next major version is mandatory before security support expires. Drupal major migrations are technically more demanding than minor updates, because they bring API changes in the core, new system requirements and potentially incompatible contributed modules.

Then there is the module landscape: a typical Drupal installation uses 20 to 50 contributed modules from the drupal.org repository, plus often custom modules implementing specific business logic. Every module must be compatible with the installed Drupal core version. During a major version jump, all contributed modules must be checked for compatibility, custom modules may need to be adapted, and configuration must be transferred. Our maintenance teams know these dependencies and plan version transitions so your operations remain continuously secured. Additional requirements come from the Drupal Security Team, which publishes coordinated security advisories on a regular schedule and expects timely patch application.

Drupal has a particularly structured security ecosystem: the Drupal Security Team publishes coordinated security advisories for core and contributed modules. These advisories follow a scheduled Wednesday release cadence and evaluate vulnerability severity using a standardized scoring system. Critical core vulnerabilities are patched immediately, contributed modules receive security releases when patched versions are available. For Drupal website operators this means: structured update management that systematically monitors these advisories and applies patches promptly is essential.

Our Drupal maintenance process is aligned with this security advisory system. We monitor the official Drupal security channels daily and apply critical core security patches within 24 hours. Contributed modules with security advisories receive updates within 48 hours, after compatibility verification on the staging environment. This keeps your Drupal installation on a secure footing at all times, without requiring you to monitor the security ticker yourself. For especially security-critical installations we offer extended security update services with reduced response times.

Drupal has a multi-layered caching system that enables excellent load times when correctly configured. The Internal Page Cache stores complete pages for anonymous users, the Dynamic Page Cache enables personalized caching for logged-in users through placeholders, and the Render Cache speeds up reuse of individual page elements. Additionally, BigPipe provides progressive page delivery, where the Drupal core first sends the base layout and loads personalized content afterwards. This combination can significantly improve perceived load times, but requires careful configuration to avoid cache poisoning through personalized content.

For high-traffic Drupal websites we recommend supplementing with an external full-page cache such as Varnish or Redis. This caching layer intercepts requests before the PHP process and can serve static pages without starting Drupal at all. Integration requires Drupal-side configuration of cache tags and cache invalidation URLs so that the external cache is correctly purged when content is updated. Our performance optimization, as part of our broader maintenance offering, configures these layers in a coordinated way and measures the impact on TTFB and LCP.

The backup strategy for Drupal installations takes into account the specific architecture of the platform: alongside the database and filesystem, the Drupal configuration system plays a special role. Drupal 8 and later store the entire site configuration in YAML files in the config/sync directory. This configuration must be backed up consistently with the database so that a restore produces exactly the same system state. We create daily full backups with a documented recovery process and conduct monthly restore tests on an isolated environment.

Backups are stored in a geographically separate data center and automatically checked for integrity. For critical Drupal portals we offer hourly incremental backups that limit maximum data loss to one hour. In an emergency we know the exact recovery time for your installation and can execute the process in a structured way. The close connection between our backup strategy and our emergency support ensures that all information is immediately available in a crisis.
