Think of a sales representative accessing the company’s resources from a hotel room or an employee working from home. On the other hand, a remote access VPN is designed for individual users needing to connect to a central network from varied locations. It ensures smooth communication between entire networks, evaluating the need for individual connections from every device. This connection is generally established between specialized hardware devices, such as VPN gateways or routers, at each location. A site-to-site VPN would create a secure bridge between these two locations, enabling them to operate as if they were on a single local network. Imagine a company with a main office in New York and a branch in Los Angeles. However, both function very differently and address distinct organizational needs.Ī site-to-site VPN is designed to connect entire networks to each other. They protect transmitted data from potential eavesdroppers or unauthorized access. Remote Access VPNīoth site-to-site and remote access VPNs establish secure, encrypted tunnels over the public internet to enable secure private communication between remote devices and networks. This mechanism allows for remote and safe access to resources while maintaining the integrity and security and integrity of the data. Inside the private network, the processing and the data is as usual, making sure the user can interact with network resources as if they were connected directly. To any stranger observers, including potential eavesdroppers, the data appears as gibberish due to the encryption. Through this encrypted tunnel, the user’s data is securely and safely transmitted. Once verified, the VPN server uses protocols, such as point-to-point tunneling protocol (PPTP) or layer 2 tunneling protocol (L2TP) combined with encryption standards, such as IPsec or SSL/TLS to create the secure tunnel. Upon initiating the connection, the user undergoes authentication, which might involve credentials, tokens or even multi-factor verification. The client communicates with the server to establish this encrypted connection. This process begins when the user initiates a connection to the VPN server, usually by launching a software client on their device. It operates on the principle of creating a secure “tunnel” over the public internet to connect a remote user with a private network. On Private Internet Access' Website How Does a Remote Access VPN Work?Ī remote access VPN is a technology that allows users to securely connect to a private network from a remote location over the internet.
