In terms of missing features, it's too soon to say as I've only had two weeks with it. That said, one of the things that caught my attention is that a number of processes seem to take up CPUs. It's a huge amount of computational power. It's justified, of course, however, this puts the solution at a level that's too high for a small enterprise to handle.

It would be ideal with the processing was more manageable. Not many customers are willing to have a dedicated server with two CPUs and one TB of memory. The cost of this is huge for a smaller organization. 

It is a standalone solution now. They need to make it into a cloud-based subscription model.

It needs more compatibility for co-managed solutions. It can also have more threats and deeper integration with Microsoft.

The product could be improved by including sandboxing capabilities in the next release.
