Hi @Dominik
What issues were you having with the setup? And regarding the WAF (that convo was between me and @Bobby_Glidwell).
There was an issue with it on Sqreen’s side but I reached out to them directly and they rolled back the change which fixed the issue. Right now their docs say they don’t support Koa Sqreen | Compatibility
But I’ve confirmed with Vlad on twitter they are working on an official beta for Koa (Strapi uses koa in the background)

Our guide will work on the latest release but not all the features of Sqreen may work.
