Penguin OS Forensic (or Flight) Recorder (POFR) vs smartmontools: 2026 Comparison

Linux incident responders on tight budgets who need process-level forensic capture without agent overhead will find POFR's kernel-based collection approach valuable, especially for post-breach timeline reconstruction on systems where you can't afford EDR licensing. The tool captures process execution, file access, and network activity at the OS level, giving you forensic-grade data without persistent monitoring costs. Skip this if you're running heterogeneous infrastructure or need real-time alerting; POFR is collection-first, designed for forensic analysis after the fact, not active threat hunting.
