Why IRFlow Timeline?
If you’re a DFIR analyst running macOS, you know the struggle of booting up a Windows VM just to triage a timeline. I got tired of it, so I built a solution.
Introducing IRFlow Timeline.
It’s a tool built from the ground up based on real-world IR experience. Every feature exists because I reached for it during an actual case, and it wasn’t there.
If you need to stay agile in the field without leaving your native OS, this is for you.
