Comparison of Norton Small Business and Norton Security Premium

What are the differences between Norton Small Business and Norton Security Premium? The descriptions are vague. It sounds like Small Business allows you to lock protected devices when stolen (PCs and mobiles/tablets?), while Premium provides bacvkup (for PCs only or for PCs and phones/tablets?).

Please clarify.  I need to protect up to 10 of my own (family) devices. I am an IT manager so would be happy with either the small business product for my family business, or the Premium providing I can understand what they offer. I currently own the Deluxe (5 devices) and Norton Internet Security (3 devices) which are up for renewal. Thanks, Keith
