So I wrote a seminar paper in grad school (MSc) with examples on how companies use method x to improve their security. It includes zero original research, no new methods and it would never ever be published in a journal, because the substance is really not there.
It gives a theoretical background of the problems itself and then different current examples from 2 companies that I researched over the internet and a conclusion. Thus, not only academic sources but also other sources (companies) are used and it basically shows the application of academic concepts.
Other researchers could use this paper to potentially find ways on how to dig deeper and how to address some problems specifically, but I did not point something like that out myself.
Does this count as research and does it make sense to hand those kind of papers to PhD admission departments?
