Unclear as to Crowdsec and Caching. I thought I saw Crowdsec will not work with ANY cache. What about WP Super Cache in WordPress and not a Server based Cache
If you talk about compatibility between “WP Super Cache” and CrowdSec, know that the two plugins work very well together.
For technical details, just use CrowdSec Bouncer in “auto-prepend” mode and WP Super Cache in “Simple” mode (the mode recommended by “WP Super Cache”).
Caveat: The Expert mode of WP Super Cache totally bypass PHP so you have to stay in “Simple” mode. Also, we have not tested with the “WP Cache caching” mode but do not hesitate to try and give us your feedback.
