What Is Virtual Private Network? How Does It Work and Benfits?

What Is Virtual Private Network?

In addition to IPsec and SSL, the other protocols used to protect the VPN connection and data encryption are Transport Layer Security and OpenVPN.

The VPN uses a network to locate a gateway device to connect the entire network in one place to another in the network – usually a small branch that connects the data center. Endpoint devices in a remote site do not need VPN clients because the gateway processes the connection.

Most VPN ( virtual private network ) connections are used for the network to the IPsec-connected site. It also features the use of MPLS carriers, not the public Internet, as a means of transmission for virtual wireless communications. Here you can also use a third layer connection (MPLS IP VPN) or Layer 2 (Virtual Private Network) over primary transport.

How a VPN ( virtual private network ) works and why you should use one

VPN services can also be defined as connections between specific computers, usually servers in separate data centers, when the security requirements of their exchanges exceed what the enterprise network can provide. Increasingly, companies also use VPN connections in remote access mode or in Site to Site mode to connect or connect resources in the public infrastructure environment as a service.

In new hybrid access scenarios, the same VPN ( virtual private network ) gateway is placed in the cloud using a secure channel from the cloud service provider to the intranet.

What are the Benefits of using VPN ( virtual private network )

The rationale for using VPN access instead of private network is often reduced to cost and feasibility: either it is impossible to have a private network, for example, a mobile sales representative, or it is too expensive.

In addition to providing remote users with a secure way to transfer or access information, VPN ( virtual private network ) services are also used for other purposes. Virtual Private Networks can hide user activity, which is particularly useful in public Wi-Fi connections. VPNs also allow users to connect to sites that can be blocked geographically.

VPN ( virtual private network ) performance can be affected by many factors, including the speed of Internet connections for users, the types of protocols used by the ISP, and the types of encryption that VPN networks use. The performance of a VPN service can be affected by poor service quality and circumstances that are not controlled by the IT department.
