The purpose of VPNs (Virtual Private Networks) is to offer companies a sharing of corporate IT resources: a VPN can therefore be seen as the geographic extension of a corporate private local network, which guarantees privacy, anonymity and security. of the data through a communication channel reserved only for authorized devices, even if located in any geographical point of the world. A VPN uses a technique that, thanks to a particular system, allows both to make your network activities invisible to unauthorized eyes (for example, cybercriminals or government censorship bodies) and to mask the IP address from which you accesses the Internet.

THE BENEFITS OF A VPN

VPNs are used in a business environment because they guarantee a series of considerable advantages and, in particular:

cost reduction: thanks to the use of the Internet as a remote connection infrastructure for VPNs, the costs of maintaining a network are significantly reduced;

mobility and smart working: remote users and employees can connect safely to corporate network resources or to each other from any place and at any time;

adaptability: a VPN-based infrastructure is easily adaptable to the needs of changing networks and is very flexible as it can create a private network both between fixed and remote offices and between remote terminals;

security: the security and reliability of a VPN comes from the use of sophisticated techniques including tunneling, authentication and encryption. Tunneling involves establishing a secure tunnel between two final remote entities enabled to create a VPN. The authentication process is necessary in order to authorize access, ensure transmission, guarantee non-repudiation. Cryptography transforms the data that can be read by means of a digital algorithm into a data that is encoded and incomprehensible to unauthorized persons;

environmental protection: the VPN technology allows to limit the movements on the territory, reducing costs. All simply IT activities, documentation, application development, CAD / CAE design to name a few, can also be carried out through a VPN connection. The VPN, combined with an innovative, conscious business ethics and a national government policy determined to reduce pollution, can contribute to safeguarding the environment.
