Surviving the Swarm: Bot and Crawler Protection for Drupal Sites

Uncontrolled bots, from aggressive scrapers to the latest AI crawlers, can grind your Drupal site to a halt, overwhelming your infrastructure and tanking user experience. As AI-driven and other bot traffic explodes, yesterday’s strategies and defenses are no longer enough. What is your plan when a swarm of traffic consumes 100% of your resources and brings down your site?

Luckily, Drupal provides a variety of great modules that can prevent your infrastructure from collapsing under the pressure. The contributed module ecosystem has a number of options to limit or completely block traffic, and there are also other tools and services, such as Web Application Firewalls (WAFs), that can further mitigate the risk, allowing you to be proactive instead of reactive.

In this session, we’ll review the current state of some of these modules and examine additional strategies that you can use, such as implementing a WAF, to protect your site. As we examine these options, we’ll highlight real-world examples of implementations and what worked (and what didn’t).

By the end of this session, you’ll have an actionable playbook to defend your Drupal site against the next bot swarm.
