go-audit vs IBM QRadar SIEM: Side-by-Side Comparison (2026)

go-audit

Linux infrastructure teams managing high-volume audit logs will get the most from go-audit because it replaces auditd's brittle single-threaded daemon with a netlink-based architecture that doesn't drop events under load. The JSON output and pluggable pipeline design mean you can stream directly to your SIEM without parsing or custom connectors, saving weeks of integration work. Skip this if you need Windows or macOS audit collection or expect vendor support; go-audit is community-maintained and requires teams comfortable reading Go source code when things break.

IBM QRadar SIEM

Enterprise security operations teams managing complex hybrid infrastructure will get the most from IBM QRadar SIEM because its native Sigma Rules support and automated case creation actually shrink mean-time-to-response instead of just adding noise to your queue. The platform scores strong on NIST DE.CM and DE.AE, meaning detection and analysis are wired tight, but it skews toward visibility and threat hunting over incident recovery orchestration. Skip this if your team is small, under-staffed, or expects a tool that will do alert triage for you; QRadar requires seasoned analysts who know what they're looking for.
