Saw this pop up on my Twitter feed. I'm not entirely sure where the "core" code lives -- website says OSS but I can't seem to find the core on GitHub. But perhaps it's just early and the core's not OSS yet, or somehow obtainable another way rn. Regardless, I thought I'd share anyways since I found it interesting and perhaps somebody else knows more about the project than I do. I'm currently using Fastly's WAF (prev. sigsci), but an OSS WAF solution would be neat to see.
