virtual private network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.
VPN technology was developed to allow remote users and branch offices to access corporate applications and resources. To ensure security, the private network connection is established using an encrypted layered tunneling protocol, and VPN users use authentication methods, including passwords or certificates, to gain access to the VPN. In other applications, Internet users may secure their connections with a VPN to circumvent geo-restrictions and censorship or to connect to proxy servers to protect personal identity and location to stay anonymous on the Internet. Some websites, however, block access to known VPN technology to prevent the circumvention of their geo-restrictions, and many VPN providers have been developing strategies to get around these blockades.censorship
.VPNCity is a brand-new Hong Kong-based VPN, and although currently in beta, it still has some interesting and unusual features. The service already has extensions for Chrome and Firefox, for instance, as well as apps for Windows, Android and iOS.VPNCity uses the OpenVPN protocol, with data encryption handled by AES-256-CBC, data authentication is SHA512, and the handshake is over TLSv1.2.VPNCity allows up to 12 simultaneous connections, which is very good considering most services set the limit at 10.
VPNCity covers 33 country locations listed alphabetically, and it has more than 3,000 servers, which is a generous number to cover those 33 countries.
There are also Windows and Mac OS apps available from VPNCity. These are pretty much identical to the mobile apps in both appearance and functionality. Again, we found the MacOS app we tested user friendly and aesthetically pleasing.VPNCity also has browser plugins available for Chrome and Firefox but at present, their VPN cannot be used on Linux.
