081 | The Modern Approach: CrowdSec — Crowdsourced Threat Protection
2025-08-13
Introduction: From Local Defense to Global Protection
In the previous article, we explored Fail2ban — a reliable and time-tested tool for defending against brute-force attacks. However, Fail2ban only works with local logs and has no awareness of what’s happening on other servers. In today’s environment, where cyberattacks are increasingly distributed and sophisticated, we need a smarter and more collaborative solution.
Enter CrowdSec — a modern, open-source Intrusion Prevention System (IPS) that leverages a crowdsourced approach to build a global threat intelligence network.
