NEC ExpressVPN and CyberGhost Discussion

I’m studying for my Computer Science class and don’t understand how to answer this. Can you help me study? Question 1 – Using the Internet, locate TWO companies that provide VPN services. Compare the TWO different services offered. Include their services, pricing, and make a decision which VPN service would be best for your own personal use should you decide to make the purchase in the future.Question 2 – What are the main reasons why a VPN is the right solution for protecting the network perimeter? Do they also provide protection for mobile devices?
