Initially VPNs were used by companies to ensure data confidentiality and secure access for everyone who works in the office. Now, there are many individuals who use VPN in browsing the virtual world. Virtual Private Network (VPN) is a technology that makes use of personal internet access connected via a VPN server even though using public internet networks. Confused about a VPN? We see how it works to make it clearer.
How do VPNs work?
The way this VPN works is to encrypt data exchanges when using the internet. Internet access points without VPN usually occur without direct filter data exchange. For example, when opening a website, the internet network provider (Internet Service Provider) that you are using will exchange data with the site being accessed. At that time data is usually not protected so that it can cause data theft or transmission of viruses. A VPN creates a network-like shield that covers and encrypts data so it’s not easy to read. The way VPN works is to process authentication because it uses network protocols, such as PPTP, ІPSec, L2TP, and SOCKS. This allows VPN users to avoid hackers, hackers, or anything else that wants user data.
Know the Main Functions of a VPN
Vіrtual Prіvate Network (VPN) has the following main functions for users:
Users who install a VPN will get more value by maintaining strict user information. This includes important company confidential data such as financial, legal, and other sensitive issues. With the encryption process, the data transfer process becomes safer.
2. Data integrity
The process of sending data via a public internet network will result in losing some information or data manipulation. For this reason, a VPN guarantees the integrity of data received by users even if using public networks such as Wi-Fi or hotspots.
3. Source Otentification
Another advantage of a VPN is that it can ensure the source will transmit the data and approve receipt if the source read is a credible source, not malware. Sources with vigorous content to post or dangerous things can be removed with the source authentication system.
Other Benefits of Using a VPN
A VPN can hide your search activities, ІP address, and the location you use when using the internet. ІSP can’t see ІP directly, what will appear is ІP VPN server, not actual ІP. VPN and its benefits make your privacy more protected.
5. Remote Access
Suppose you are at home or elsewhere, you can still access the computer or network of the company office. Manage work remotely and be more efficient when something happens. VPNs increase the mobility of corporate work.
6. Cost savings
With more benefits and without having to install a new network, installing a VPN is considered cheaper.
Cutting paths blocked by the government is an advantage of a VPN. You can access restricted web sites based on geographic zones because ІP is tracked using ІP servers located in different countries. Well, here is the ultimate discussion about VPNs and their benefits. Of course this app has some drawbacks too. One of them is that there are limitations to use, sometimes the connection is slow and not stable, also the manual configuration is quite difficult.
