Snort 3 isn’t trying to be flashy. It doesn’t need to be. It’s a laser-focused network watchdog built for professionals who understand the value of seeing traffic for what it really is — and stopping it before it becomes a problem. For teams who’d rather build something robust than buy into another black-box platform, Snort still delivers where it counts.
OSSEC doesn’t advertise itself. No dashboards, no web GUI, no flashy interface. But it watches. It keeps an eye on your logs, system files, and odd behavior. It’s the sort of tool you install, forget about for a while — and then it catches something weird in /var/log/auth.log, and suddenly you remember why it’s there.
Wazuh isn’t just another SIEM. It’s not a shiny dashboard glued to a log collector. It’s a security platform that goes deep into endpoints — files, processes, configs — and tells you when something drifts out of line. Then it correlates that with known rules, compliance policies, or threat intel, and lets you act.
CrowdSec is an open-source intrusion detection and prevention system (IDS/IPS) that goes beyond simple rule-matching. Designed for today’s distributed infrastructures — cloud, containers, hybrid environments — it monitors system and application logs in real time, identifies suspicious behavior, and can automatically mitigate threats by blocking malicious IPs.
