CST VerdictBased on our analysis of available product data, here is our conclusion:
AVML (Acquire Volatile Memory for Linux)
Incident response teams running heterogeneous Linux environments will move fastest with AVML because it acquires memory without needing to know the kernel version or distribution beforehand. A single compiled binary handles RHEL, Ubuntu, Alpine, and custom kernels, which eliminates the pre-deployment reconnaissance that typically delays forensics by hours. Skip this if your team needs Windows or macOS memory acquisition, or if you require a commercial vendor backing incident response with SLAs and expert support.
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.
