VPN

A Virtual Private Network (VPN) is a technology that establishes a secure connection between different locations or users via a public network such as the internet. Encryption and authentication are used to protect data as if it were being sent within a private network. VPNs are particularly useful for companies that want to enable their employees to access company resources securely and flexibly from different locations.

Application in customer service

In customer service, a VPN enables employees working at different locations or from home to securely access central systems and data. This ensures that sensitive customer data remains protected during communication, while also allowing seamless and rapid collaboration between different teams. It also provides protection against cyber-attacks and data leaks, which is essential when handling sensitive customer data.

Types of VPNs

There are different types of VPNs that offer different functions depending on the requirements and area of application. These types differ primarily in how the connections are established and which user groups benefit from them:

• Remote-access VPN allows individuals to connect securely to the corporate network from a remote location. This is particularly relevant for companies with many mobile or decentralized employees.

• Site-to-site VPN connects entire networks of different locations so that data can be transferred securely between sites. It is often used to connect branches of a company with each other.

• Client-to-site VPN is used by individuals to connect securely from outside the company network, e.g. when working from home.

Advantages of a VPN

• Security: VPNs offer an encrypted connection that protects sensitive data and secures communication against unauthorized access.

• Flexibility and mobility: Employees can securely access the company network from anywhere, which is particularly essential in times of remote work and working from home.

• Cost savings: As companies establish a secure connection via the internet, the high costs for their own private networks or leased lines are eliminated.
