A virtual private network or VPN is an encrypted connection over the Internet from the device to the network. The encrypted connection ensures that confidential data is sent securely. This prevents unofficial individuals from intruding on the traffic and enables users to work remotely. VPN technology is extensively used in corporate environments.

How do virtual private networks (VPN) work?

A virtual private network (pronounced as 가상 사설망 in the Korean language) extends a corporate network through an encrypted connection over the Internet. Because the traffic between the device and the network is encrypted, traffic remains private while in transit. These employees can work outside the office and remain securely connected to the company network. Even tablets and smartphones can be connected via a VPN.

Is VPN traffic encrypted?

Yes, traffic on virtual networks is sent securely by creating encrypted connections over the Internet called tunnels. VPN traffic from devices such as computers, tablets, or smartphones is encrypted as it traverses this tunnel. Employees who are outside the office can then access the corporate network via a virtual network.

Type of VPN

Remote Access:

VPN RAS securely connects devices outside the corporate headquarters. These devices are known as endpoints and can be tablets, laptops, or smartphones. Advancements in the technology of VPN have made it possible to carry out endpoint protection checks to ensure they can reach a specific location before connecting. Think of remote access as a computer on a network.

Site-to-site VPN:

A site-to-site VPN connects corporate headquarters to branches via the Internet. Site-to-site VPNs are used when distances to make direct network connections between offices are impractical. Special equipment is used to make and maintain contacts. Think of site-to-site access as network-to-network.
