Big fan of bunny.net as CDN, however Cloudflare is my "smart" filter for all kind of attacks, AI scrapers, malicious traffic, etc.

Am I missing something or is bunny.net not actually a replacement for that?

They've recently introduced bunny.net Shield to add a security layer. I've not made use of it yet so I don't know what the coverage is like or how effective it is: https://bunny.net/shield/
