If users are still double-minded about using NordVPN, take a look at this complete privacy analysis. We connected to a stealth server in Hong Kong and then performed a test via IPLeak.net. The results showed that the VPN was successful in hiding our true US location. It displayed a Hong Kong IP Address for our IPv4 and public address. The DNS address also showed that we were connected to a single server located in Hong Kong.
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.
HotSpot Shield is a product that has had some ups and downs in terms of our editorial coverage. Back in 2016, they picked up some very positive coverage based on founder David Gorodyansky comments about protecting user privacy. Then, in 2017, a privacy group accused the company of spying on user traffic, an accusation the company flatly denies. Finally, just this year, ZDNet uncovered a flaw in the company's software that exposed users. Fortunately, that was fixed immediately.
