I’m running a website that is getting a lot of bot traffic and found Cloudflare free rule tier to be a bit limiting. (5 custom rules with length limits)
Ive got subnets for major VPS providers to block and will run analysis against my traffic to build on these lists.
What do others do?
I’m contemplating my Cloudflared tunnel into Crowdsec to my app.
Edit: Adding in image of my analysis of the IPs scanning for vulnerabilities.
If you want to DIY something, I have a bash script that builds OpenResty with NAXSI from source. Most of the web apps I write anymore are actually in Lua, for OpenResty, maybe with an API written in something else. But I also help other members of my team deploy their Node and Python apps and stuff, and I always just park those behind OpenResty with NAXSI, just doing a standard nginx reverse proxy.
How easy is it to configure?
My goal is to download some lists from github and generate one big ban list to feed into the WAF but the community lists of Crowdsec might negate the need.
There’s a learning curve, but if you’re familiar with WAF’s it’s not hard.
