One of the best ways we can choose to hide our privacy, increase our security, avoid being tracked over the network and ensure that all information travels safely from our device or computer to the destination is by connecting through a private network virtual, commonly known as VPN. If on any occasion we have tried to set up a VPN to connect to both an external server and another controlled by us, surely we have found ourselves in the position of having to choose the type of network that we are going to configure.
Next, we are going to see the different types of VPN networks and the main characteristics of each one or buy vpn with paypal so that we can choose the one that best suits our needs.
Different types of VPN networks
When we send data through a VPN network, it is encapsulated using an encryption protocol previously configured in both the sender and the receiver and is sent to it through a direct connection established with it. As the data is encrypted, even if other nodes, routers or hackers get hold of it, they will not be able to see the information they contain since only the recipient has the keys necessary to decrypt the data.
These networks make use of an application (client) that is in charge of completely controlling the connection and establishing it. In order to browse this network, users generally need a username and password that identifies them on the server. Once the session is started, the secure connection is established so that all communication between the client and the server is secure.
This is the fastest and easiest method to connect virtually any computer or device to a secure network to navigate through it.
The most widely used protocols for this type of connection are L2TP (Layer 2 Tunneling Protocol), PPTP and SSTP. Also, if we want higher security, we can use protocols like Fastest VPN, although they are somewhat more complicated to use (since they work through certificates).
This type of connection is used to connect two or more networks to each other through an insecure network such as the Internet. These connections are generally used by companies and organizations that seek to securely connect two or more locations around the world without having to physically connect them, something totally impossible.
Although there are several protocols for this type of connection, the most used due to its simplicity is IPsec. To establish the connection, the devices in charge of encapsulating and de-encapsulating the traffic that travels from end to end must be defined. The users and passwords and the certificates to be used are also defined, as well as the type of traffic that will travel through said network.
IPsec networks are much more dynamic than client-based VPN networks, so from them we will be able to configure the type of traffic and even apply a series of rules or filters, increasing both the performance of the networks and the security.
Which VPN connection should I choose?
As we have said, network-based VPN connections are designed especially for companies and organizations since the security is very high, but they are very complicated to configure. Additionally, these connections require special hardware to establish the end-to-end connection.
If we are home users and what we want is to protect our connections, for example, when we connect from public networks, a client-based connection, both managed by us (if our router or home server is configured as such) and through a central server (hiring the service with another company) will protect us perfectly.
