CST Verdict

Based on our analysis of core features, integrations, here is our conclusion:

chkrootkit

Linux administrators managing legacy or air-gapped systems need chkrootkit because it runs entirely offline and requires no agent installation, making it the only viable rootkit detection option when your infrastructure can't phone home. The tool performs over 100 signature-based checks for known rootkit artifacts and kernel-level compromises, catching what file integrity monitoring alone will miss. Skip this if you're running modern EDR across your fleet; chkrootkit prioritizes detection over response and won't integrate with your SOC workflows, making it a one-off forensic tool rather than a continuous monitoring layer.
