Crowdsec is pretty amazing, easy to set up even if you’re not a security expert, and the documentation is straightforward.
The plugin is very well supported, and they don’t just blame plugin conflicts, but actually try to understand the problem and help.
I would love to see support for multisite, in the form of having network-wide options instead of having to configure the plugin individually per site.

My WordPress server & installation (including PHP version) met or exceeded all requirements. I was running WordPress 6.01 which apparently hasn’t been tested. After downloading and activating the plugin, my site experienced a “Critical Error 503” error and I was unable to access the Admin Dashboard. I was able to overcome this restriction after 2 hours and 15 minutes and deactivating and deleting the CrowdSec plugin allowed me to regain control of my Admin Dashboard and the website was back online.
