CrowdSec
CrowdSec is a security program that watches server logs and web traffic for attacks, then blocks the attacking internet addresses. It also shares blocked addresses with a community blocklist so other users are protected too. It is aimed at system administrators and IT teams who run servers or websites.
How hard it is to start using it. Easy: install it like a normal app, or use it in your browser. Advanced: you run it on your own server, use the command line, or it is a tool for developers.
