Anti exploit is mainly for 0day mitigation and sufficiently orthogonal to the other components. Everything you’ve said about updates, more layers is true but this doesn’t change that anti exploit is excellent mitigation on its own right
Oh don't get me wrong, I am in no way against someone using an anti-exploit program, I understand it can be very useful. My post was mostly to highlight the fact that I don't believe Eset's anti-exploit feature has been thoroughly tested, so I don't think we know for sure how it performs. The same can be said for most products that have anti-exploit capabilities, as it's very difficult to test anti-exploit programs/features. Knowing Eset, it's probably very capable, but like every other product it won't be bullet proof, hence my reasoning about keeping everything up to date.
As I've said there's more to Eset than one particular feature, they are all meant to compliment one another. You have to look at the product as a whole, not just one aspect of it and the same can be said for every other program out there.
