Virtual Private Network (VPN) establishes a secure connection between your device and a remote location. It generates a tunnel from the device to the VPN service. All the online traffic goes through this tunnel to the VPN server, and then to the internet service that it’s connecting to it. This hides the origin of your traffic and makes it look like it comes from your VPN service. All your traffic is encrypted and your IP address is hidden, so only your service provider can know what you are doing.
VPN uses encryption to scramble data when sent over a Wi-Fi network, making the data unreadable. A VPN extends a corporate network through encrypted connections made over the network. Because the traffic is encrypted between the device and the network, which allows traffic to remains private as it travels. An employee can work remotely and still securely connect to the corporate network.
Different Types of VPN (Virtual Private Network):
Remote Access: a remote access VPN securely connects devices outside the corporate, the devices are known as endpoints such as laptops. Advances in VPN technology have allowed security checks to be conducted on endpoints to make sure they meet certain criteria before connecting
Site-to-site: A site-to-site VPN connects the corporate office to branch offices over the Internet. Site-to-site VPNs is used when distance makes it not possible to have direct network connections between the offices.
How is VPN useful for enterprises?
VPN is useful and important for enterprises because it protects organisations from data breaches. VPN secures the enterprise data, it also allows remote access such as connecting to IT resources, transferring data and it secures and protects the network from malicious websites. VPN is very useful for enterprises because it allows an access control system that is authenticated and authorizes users by evaluating required credentials, meaning that it verifies that the person is who they claims to be, and authorizing the appropriate access levels and permissions associated with the username or IP address.
The Tor Browser is a free, open-source project enabling you to surf the web anonymously. The difference between Tor and a VPN is how there are multiple VPN tools and service providers available but only one Tor browser network. Tor relies on a decentralized layer of independent nodes to transfer data securely, while VPN software connects to a central server to provide a secure VPN tunnel. VPNs work to protect your online anonymity, VPNs are the most secure choice if utilized properly. Tor is a free browser that will encrypt your requests, however, it’s slow and doesn’t have access to all sites. Therefore, for organizations, VPN is a better option rather than Tor.
A proxy acts as a gateway, it’s ideal for basic functions like anonymous web browsing and managing content restrictions. Proxy servers excel at IP masking and misdirection, making them good for viewing location limited content. Proxy allows users to bypass content restrictions and monitoring or enforce website content restrictions so that you can’t log into certain web pages on organisations network services . Both VPNs and proxies enable a higher degree of privacy than you might have, allowing you to access the internet secretly by hiding your IP in various ways, however, VPN is a better option than Proxy as it provides privacy and security by routing your traffic through secure servers and encrypting your traffic. A proxy simply passes traffic through a mediating server but doesn’t offer protection.
During Covid-19 pandemic it causing people to work from home, this allowed VPN to be a tool used by the majority of companies. enterprise VPN servers became dominant to a company’s backbone. According to a new investigation from independent research, demand for VPNs increased by 44% and remains 22% higher than pre-pandemic levels. While US demand has waned slightly since, it peaked at 65% above average. The largest hikes in VPN demand came out of Egypt the demand has reached over 224%, followed by France, whose increase peaked at 80%, followed by the US at 41% and the UK at 35%.
