To be fair, I'm looking at this stuff form a pentesters perspective, not a corporate security perspective, so my use case is different and I'm not installing agents on my client's machines. Also this is just one part of the process, I don't take any vulnerability scanners results as the final word, but it does help speed things up if it's accurate. When stuff is missed, I have to do a deeper dive with manual checks, which just takes time that I don't always have.
