We like that the company offers a connection kill switch feature and, for those who need it, there's an option to get a dedicated IP address. VyprVPN is a standout in their effort to provide privacy, and thwart censorship. When China began its program of deep packet VPN inspection, Golden Frog's VyperVPN service added scrambled OpenVPN packets to keep the traffic flowing. 
VPN technology was developed as a way to allow remote users and branch offices to securely access corporate applications and other resources. To ensure safety, data travels through secure tunnels, and VPN users must use authentication methods -- including passwords, tokens or other unique identification procedures -- to gain access to the VPN server.
Yes, VPNs are completely safe to use and operate, whether it be unblocking websites/streaming services or engaging in P2P/Torrenting activities for downloading pirated stuff. However, it is imperative that you choose the right one, as to protect your identity online. You would not want to compromise on online safety, hence always go for a VPN that comes equipped with advanced features, a huge list of servers, 24/7 customer support, and reasonable pricing.
The servers of the company are numbered around 2000, which might be less than other VPN services. However, the spread is wider as it provides more than 148 cities and over 94 countries to choose from. The company allows for up to three devices to use its service. As with NordVPN, this company also keeps the exact numbers and other details around its operations rather vague.

Unlike ExpressVPN, CyberGhost has a section of its interface dedicated to streaming. Version 7 has specialty servers for over 50 streaming platforms, with everything from movies to music in the mix. Each server is optimized for a particular platform based on its location. For example, Channel 4 is optimized on a U.K. server and Netflix is optimized for the U.S.
When you connect your computer (or another device, such as a smartphone or tablet) to a VPN, the computer acts as if it’s on the same local network as the VPN. All your network traffic is sent over a secure connection to the VPN. Because your computer behaves as if it’s on the network, this allows you to securely access local network resources even when you’re on the other side of the world. You’ll also be able to use the Internet as if you were present at the VPN’s location, which has some benefits if you’re using pubic Wi-Fi or want to access geo-blocked websites.
OVPN was regularly the fastest VPN in our tests regardless of the time of week or location. We also liked the app’s clean design and its simple and well-labeled settings pane. But OVPN is a small startup with a limited server network: At this writing, the company has servers in just seven countries, none in Asia. That makes it less versatile for finding less congested routes or geoshifting. OVPN also hasn’t released an Android app yet, so even non-iOS device owners will have to resort to the clunky, third-party OpenVPN Connect app on their phones. When we reached out for details about the company’s operational security, founder and CEO David Wibergh was open to questions and gave us answers that led us to believe that the company acted in the best interest of its customers’ privacy and security. He noted that after an uptick in data requests from local authorities in Sweden—all of which OVPN responded to by explaining that it lacked any pertinent data—the company published a blog post to detail just how little information it keeps.
IVPN goes further than the other leading candidates we considered by being transparent about who runs the service and is responsible for your privacy. The company lists its core team on its website, and its small team has an online presence on a variety of platforms. In contrast, only one employee at ExpressVPN has a public face: VP of marketing Harold Li gave us detailed answers to questions about policies and internal security, but couldn’t tell us much about who else worked there. (We discuss ExpressVPN in more detail in the Competition section—that company was almost our top pick but for this issue.)
CyberGhost has been around since 2011 and has come out strongly as a supporter of "civil rights, a free society, and an uncensored Internet culture." We really liked how the company specifically showcases, on their Web site, how folks normally prevented from accessing such important services as Facebook and YouTube can bring those services into their lives via a VPN.
