CNSL

Self-hosted SIEM that correlates SSH, web, and database attacks and blocks them automatically

PlatformWebfreeglobal

CNSL is a free, open-source, self-hosted SIEM for Linux that correlates activity across SSH, web, database, and cloud logs to recognize coordinated, multi-stage attacks instead of isolated failures on a single log. It automatically blocks recognized attacks, tracks an attacker's progress through the kill chain, and shares threat intelligence across multiple servers in real time. It's built for system administrators securing self-hosted Linux servers who want cross-log attack correlation rather than single-log monitoring.
