A VPN uses a range of encryption technologies like IP security (IPSec), layer 2 tunneling protocol (L2TP)/IPSec, as well as secure sockets layer (SSL) and transport layer security (TLS). It keeps all communication between remotely-located employees safe from the cybercriminals, without disturbing the flow of work. Enhanced security: The fundamental functioning of a VPN strengthens the security of network traffic.Those predictions have come true to a large extent. In an article in Computer World (1997), author Bob Wallace told Tom Nolle, chief strategist at ExperiaSphere and president at CIMI Corp, that VPNs would let companies close ranks with suppliers, business partners, and remote sites around the world, and support growing legions of remote workers. Advantages and Disadvantages of Using VPN This means that the Internet, for all practical purposes, remains a relatively insecure set-up.Ī VPN gives you the security you need while harnessing the power of the Internet. Transmission, rather than security, was the primary concern then and even today. This was achieved by moving data on the IP, which has rules on how data must move between these points.Ĭomputer servers facilitated this over long distances, and if one failed, another would instantly take up the job. When the Internet was conceptualized, the primary idea was to send data from point A to point B in an efficient manner. The receiving address gets the capsules and decrypts the information without seeing the origin address.The data is placed in a secure capsule and sent through a private tunnel created on the Internet that masks the origin IP address.The service encrypts the data that you are sending out.How does VPN work? Put simply, VPNs work in three steps: With VPNs making use of a separate server for Internet usage, hackers and cybercriminals can effectively be kept at bay. VPN usage and data privacy are strongly interrelated. The CyberEdge Group 2020 Cyberthreat Defense Report revealed that 80.7% of organizations in seven major sectors had been affected by at least one successful cyberattack in 2020. Another study conducted by the University of Maryland concluded that hacker attacks happen at a frequency of every 39 seconds. The increased demand will be fueled by the need to protect against cyber-crime-related issues. VPN significantly reduces the threat of cyber-attacks and security breaches.Ī 2019 report by Knowledge Sourcing Intelligence LLP projected a CAGR growth rate of 6.39% to touch USD50.153 billion by 2024 for VPNs. This can be safely done because their IP addresses are masked, even while accessing public Wi-Fi networks.

With the help of a VPN, an organization with multiple offices globally can share its data with its employees, irrespective of location. When used for businesses, a VPN only allows authorized personnel to access data of the organization through the Internet. The most common use of VPN technology is keeping all online recreational activities of an individual untraceable, even when accessed on a private Wi-Fi network. It uses tunneling protocols to encrypt sensitive data from a sender, transmit it, and then decrypt it at the receiver’s end.īecause the user’s internet protocol (IP) address is masked and untraceable during this process, it provides a high level of privacy. The ambit of the technology gradually grew to accommodate the needs of businesses and corporates of varying sizes.Ī virtual private network is a computer network that gives online privacy to a user by creating an encrypted connection from a device to a network.

It is precisely to address this pain point that the concept of virtual private networks came about. The security of personal data and activities while using the Internet has always been a matter of concern.
