WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks (VPNs). [5] It aims to be lighter and better performing than IPsec and OpenVPN, two common tunneling protocols. [6]
In computer networks, a tunneling protocol is a communication protocol which allows for the movement of data from one network to another. They can, for example, allow private network communications to be sent across a public network (such as the Internet), or for one network protocol to be carried over an incompatible network, through a process called encapsulation.
Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).
A HTTP tunnel can also be implemented using only the usual HTTP methods as POST, GET, PUT and DELETE. This is similar to the approach used in Bidirectional-streams Over Synchronous HTTP ( BOSH ). A special HTTP server runs outside the protected network and a client program is run on a computer inside the protected network.
IPsec uses cryptographic security services to protect communications over Internet Protocol (IP) networks. It supports network-level peer authentication, data origin authentication , data integrity , data confidentiality ( encryption ), and protection from replay attacks .

Update and Secure your computer • Enable your firewall. • Update your software, such as AOL Desktop Gold Software, McAfee, Adobe products and Java. • Regularly scan your computer for spyware and viruses using anti-virus software. If you don’t have a one, we recommend McAfee Internet Security Suite – Special edition from AOL.
In computer networking, Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It uses encryption ('hiding') only for its own control messages (using an optional pre-shared secret), and does not provide any encryption or confidentiality of content ...
