It's easy to use, it has all those features you need like file storage etc., but not too many bells & whistles that could make your life difficult if they are unnecessary or complicated for what we require from our system; everything seems pretty straightforward in terms of its functionality. I have no complaints about this product as such so far! We've been using ViaCrypto since 2012 and haven't had any issues with their software/service yet (we're still running now). If there was one thing that would benefit us more than anything else it would be additional training options when needed and perhaps some form of support available 24 hours 7 days? Yes please!! Nothing really specific other then general comments above.
