A VPN allows a user to securely access private networks with complete peace of mind. Whether you want a VPN in a country like South Africa for example, or in any other country, in the modern age, everything is possible. It has similarities to a firewall, except that a VPN disguises your IP address, so you are untraceable. By changing your IP address a top VPN like IPVanish ensures that if anyone is spying on you, they will not see your correct geographic location. VPNs use a combination of encryption protocols and dedicated connections; therefore, even if a hacker tries to access some of your data, they would be unable to read due to it being encrypted. With this level of encryption and security, you can always be sure that you are browsing anonymously with your VPN.
Secure Shell (SSH) is a secure version of Telnet that you can use to log on and open a command line on a remote machine. You can also use SSH to establish an encrypted tunnel between two machines, effectively creating a VPN. Different versions of SSH use RSA or Digital Signature Algorithm (DSA) for secure key exchange and 3DES or Blowfish for data encryption. You can use a free program such as Stunnel (http://www.stunnel.org) along with a free version of SSH such as OpenSSH (http://www.openssh.org) to tunnel protocols such as Web and mail protocols through an encrypted SSH tunnel. All you need is a machine at either end running both these programs. SSH and Stunnel are an inexpensive way to implement a VPN, although setting up such a VPN requires a lot of configuration and might not scale to handle a large number of machines. An SSH VPN can, however, make a nice solution for connecting two servers that need to communicate securely, such as a Web server and a back-end database server.
We also dove deeper into the desktop apps of the top-performing services. Great apps have automatic location selection, easy-to-use designs, and detailed but uncluttered settings panels. We set up each service’s Android app on a Samsung Galaxy S8 running Android 7.0 Nougat. We took into account how easy each one was to set up and connect, along with what options were available in the settings pane.
If your VPN manages to shift your IP address, it does not mean you receive complete anonymity. Many rookie users are not aware that DNS Leaks are equally dangerous. They can easily expose your identity to your local ISP. To ensure ZenMate is safe to use, we performed a separate DNS Leak Test. From the results below, you can see only a single DNS server is visible. It is from Switzerland (the server we connected to).
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.
We haven’t tested every single VPN product on the market because there are hundreds of them. What we did was establish affiliate relationships with a number of what we think are leading VPN services on the market for private use. We then analysed those products by performing a series of objective tests, assessed our subjective personal user experience, and reported our findings to help you make an informed decision to choose the right VPN service for you. Of course, there are other VPN products out there and you should feel free to shop around outside this site. However, on this site, all testing and findings were performed by a qualified member of our staff with a minimum of a university bachelor degree in computer science and over 10 years of experience in software development. Some of the VPN software used for testing was given free for testing purposes. Most were actually purchased. We think you will struggle to find another website out there which actually downloads and tests the different VPN software using a qualified professional.
It’s in 148 locations, each with varying numbers of servers. ExpressVPN’s network spans 94 countries, which is unmatched by most competitors. It covers every continent except Antarctica, with solid coverage in Asia and Africa. Some servers in exotic locations, such as Vientiane or Algier, are virtual, though, so beware if you’re concerned with security.
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.
