Fail2Ban allows you to easily temp ban ips if they do a certain action, like visiting a specific path, sending too many requests etc. This helps you protect your server from random crawlers trying to find vulnerable servers and just list your server at all. Although the best thing is still to have a server thats up to date and hardened, its still not bad to also just block malicious ips.
