With one larger VPN and two smaller VPNs, there are a lot of differences that you might see on the surface of these VPNs. While Private Internet Access has thousands of servers, both Unblock and Zenmate have less than 30 servers. This doesn’t mean that the smaller VPNs are less efficient. Even with a lower number of servers, both companies are spread across several countries. What it comes down to here is weighing the costs and the benefits. Zenmate is meant specifically for browsers and mobile devices since it is a plug-in that you can use with most browsers. This means that it doesn’t cover all your internet activity, just browser activity. Private Internet Access, being the larger company, can protect you from more as well as give you access to all the Netflix and Hulu that you want. Unblock has great customer service and the option to resell VPN services for their customers. When it comes down to picking just one of these services, it comes down to what you are most concerned about.
