Secured Communications Through VPN

Virtual private network or VPN is a tool used by individuals for personal and business purposes. It establishes a secure network, by creating a virtual tunnel encrypted over a public network like the internet. For business purposes, it is used to lease classified lines to connect local and international office branches. Often, the amount spent by businesses to buy VPN services is huge because the range of network connectivity is extensive.

Since VPN is constructed within the infrastructure, data exchanges and communications are protected from outside. Thus, VPN prevents malicious threats and hackers from accessing important data and information about the company. Cited below are the main goals of VPN in companies’ communication processes.

Prevent Security Risks
The main goal of VPN is to make all communications secure and invisible to users outside the company’s infrastructure. To prevent security risks, the role of VPN is to segment and partition important communication sent out by the company’s staffs. On the other hand, it is important to note that secure communication does not mean total isolation to the rest of the world. VPN still uses the internet but with virtual encryption.


 Data Privacy
Inside a company infrastructure, privacy is very important. The level of privacy required is often set by the organization itself. The level of security is usually based on its own risk assessment. If classified data is to be transmitted across a VPN, the company can apply encoded or encrypted messages to protect the information and to ensure that the data will be read by the intended recipient only. It can also hide your actual location and one example is
New Zealand VPN.
Control Network Traffic
An extranet is a computer network that permits controlled access from the outside.
VPN can be used to generate a network that is partially accessible to authorized users outside an organization. In business to business context, these are usually partners, vendors and suppliers that the company is constantly transacting with.
Listed above are some of the main objectives of VPN in company’s communication processes. Security risks can happen if the company will not limit user access to classified information and sensitive systems. Planning a system that will give authorization only to those who need to share and transmit information can definitely help prevent future security risks. Many companies are now adopting VPN, because high service quality VPN has proven to be better choice than the traditional circuits. VPN service can control network traffic and still providing important security features like privacy and data security.
