I am assuming they're referring to TinyWall's "allowlist this process" or time-based rule capabilities. Windows Defender firewall can allowlist applications, but you have to feed it a path to the executable image.

Such things have been around for ages - I remember getting a free license somehow for a host-based IDS back in the Windows Vista times (struggled to look it up but I believe it was SAX2 by Ax3soft). It had some interesting features but running on an underpowered laptop the overhead cost more frustration than it was worth.
