Is esports protected from cheaters?

Recently esea a leading tournament provider announced a lan anti cheat device. (link)

This can be partly traced back to figures in the csgo scene like DanM, Richard Lewis, and others who have been advocates of greater lan security measures. The growth of the subreddit vac sucks and the growth of DanM’s channel show a decent amount of esports fans are concerned about lan cheating. I also remember cheating accusations against overwatch players taimou and surefour. In this wake of this announcement and moves to bring awareness to potential cheating I believe the question should be asked, is esports as a whole safeguarded against potential cheating.
