alt Hacker NewsNot sure what you implemented.
They provide several IP blacklists. None of those seem to be false positives. You can also add custom 3rd party blocklists.
They also provide several different rulesets. It is up to you to choose which ones to use and fine tune. LLMs can be very helpful with that.
And there are 3rd party dashboards and tools that help you manage it more easily.
I use the free version as a simple WAF on multiple servers and it blocks a lot of bots. It did require some initial finetuning though.
Are there any better open source solutions?
We had the main community blocklist and several of their pricey paid blocklists enabled in a PoC capacity. We had a lot of legitimate users end up blocked. In some cases these may have been VPN exit nodes, or users on CG-NAT, or devices on a shared network with some other compromised / bot device. I didn't get 100% of the details, just that we were inundated with support requests from real users that ended up blocked.
