New open source project called CrowdSec crowdsources internet security... A bit like a crowd-sourced Fail2Ban

CrowdSec is a new security project designed to protect servers, services, containers, or virtual machines exposed on the internet with a server-side agent. It was inspired by Fail2Ban and aims to be a modernized, collaborative version of that intrusion-prevention framework.

A scenario: "A company protecting its customers from DDoS attacks set up a DDoS mitigation strategy relying on Fail2Ban. When one of its customers was attacked by a 7,000-machine botnet, CrowdSec was able to ingest all the logs and successfully banned more than 95% of the botnet, efficiently mitigating the attack, in less than five minutes. For the sake of comparison, Fail2Ban would have needed to process several thousand logs per minute, which is quite challenging and would have taken nearly 50 minutes to deal with this attack."
