Companies do not always have their own physical data access channels between divisions (stores, branches, etc.) that are distributed territorially. In such cases, connections to the global network and VPN are used to ensure a high level of security of the corporate network. In this way, the Internet becomes an extension of the corporate distributed network.
VPNs are useful for businesses that prefer private, secure traffic, and are especially useful for organizations that have more than one office located in widely different geographic locations. These businesses often need to access resources hosted on the core network, which may include servers that facilitate email or store data. In some cases, the server can be the working center of an application necessary for the company’s business. In this case, the VPN can give all sites full access to the application as if it were hosted in their physical facility. A VPN is indispensable if each branch or office has its own resources or hosts unique processes, access to which will benefit the entire company. For example, if each office had unique information that was constantly updated and customized for customers, a network VPN would give decision makers secure access to everything being developed, regardless of their physical location. .
It is also possible to set up VPNs used by two or more different companies that want to share certain resources but keep others private. In this case, each organization connects to the VPN network and chooses what it wants to make available to other companies. This way, they can collaborate and share without revealing sensitive data.
