Penguin OS Forensic (or Flight) Recorder (POFR)
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.
DevSecOps teams investigating container and Kubernetes incidents will get the most from Sysdig Stratoshark because it gives you system-call-level visibility into what actually executed inside your workloads, not just what the logs claim happened. It's free, runs on Linux and Kubernetes without agents, and integrates directly with Falco for runtime context. Skip this if you need audit compliance reporting or SIEM correlation across your entire infrastructure; Stratoshark is a forensics tool for deep runtime inspection, not a centralized security monitoring platform.
