Fastest 加速 - 90 加速

A virtual private network (加速) 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. Applications running across the 加速 may therefore benefit from the functionality, security, and management of the private network.

Individual Internet users may secure their transactions with a 加速, to circumvent geo-restrictions and censorship, or to connect to proxy servers for the purpose of protecting personal identity and location. However, some Internet sites block access to known 加速 technology to prevent the circumvention of their geo-restrictions.

加速s cannot make online connections completely anonymous, but they can usually increase privacy and security. To prevent disclosure of private information, 加速s typically allow only authenticated remote access using tunneling protocols and encryption techniques.

Mobile virtual private networks are used in settings where an endpoint of the 加速 is not fixed to a single IP address, but instead roams across various networks such as data networks from cellular carriers or between multiple Wi-Fi access points. Mobile 加速s have been widely used in public safety, where they give law enforcement officers access to mission-critical applications, such as computer-assisted dispatch and criminal databases, while they travel between different subnets of a mobile network.
