Benefits of VPN and How it Works
Virtual Private Network or commonly known as VPN is a virtual private network service application between devices on the Internet. With VPN, you can communicate and access content more securely because all your identities are encrypted by the VPN.
In its use, VPN has been used for various needs such as:
- Communication between headquarters and branch offices
- Remote access to the office network during WFO or WFA
- Access to banking such as VPN Tarumanagara
- Access geographically blocked content such as Reddit, Netflix global, etc.
- Hide browsing and local network activity while using free public Wi-Fi
- Download files restricted by ISPs, such as torrent files
- Access video chat applications for certain countries, such as Ome TV. With VPN, Ome TV users from Indonesia can video chat from specific countries based on the VPN server used.
Aside from these uses, VPN has specific features that have many uses. Curious about the benefits? Continue reading this article:
User Security and Data Protection
As an application that can guarantee user privacy, the role of VPN is as follows:
1. Disguise IP Address
When you access content on the Internet, both applications and websites, you allow your IP address to be read by the content provider’s server. With the help of a VPN, the IP address you share is no longer your original IP address, but a new IP address provided by the VPN. Meanwhile, your IP address is encrypted by the VPN.
2. Encrypt Data
VPN encryption is the process of scrambling online data so that unauthorized parties cannot obtain or use the data. When you access content, the VPN encrypts all information sent to the content server.
In the process of sending from the content server to you, the VPN service creates an encrypted tunnel so that your information packets are wrapped in an outer packet and encrypted by encapsulation. When the information packet arrives at the VPN server, the outer packet is removed so that you can access the information inside through the decryption process.
3. Accessing Blocked Sites
In Indonesia, several domain name systems (DNS) can be blocked by the Ministry of Communication and Information Technology for various violations. For example, the Telegram application was once blocked by the Ministry of Communication and Information Technology due to violations of distributing inappropriate content.
This is certainly a problem for those of you who use Telegram as a means of communication on a daily basis. To get around this block, you can use a VPN. With a VPN you can access the Telegram server using a virtual IP address that is not restricted by the Ministry of Communications and Information Technology system.
Internet Freedom
When surfing the Internet, you definitely want unlimited Internet access. Some of the benefits of VPN that can support your internet freedom are as follows
1. Bypassing Geographic Restrictions
Geographic restrictions are used by content providers to limit access to online content based on regional or national territory. This restriction is usually done for legal and copyright reasons, where certain content is only available in certain regions.
For example, HBO Go Asia contains streaming movies only for the Asian region, while HBO contains streaming movies worldwide. By using a VPN, you can access HBO’s global content. This is possible because the VPN allows you to access the HBO content server from the global server.
2. Access Restricted Content
In Indonesia, some types of content are restricted by the government. For example, not all movies on Netflix are available to Indonesian Internet users. To access these movies, you need to use an IP address from countries that allow free access to Netflix.
To get IP addresses from these countries, a VPN with multiple global servers can help you provide the appropriate IP address.
How VPN Works
Here is the process of how VPN works:
- On the user device, the user activates the VPN application and selects a server.
- The VPN application sends a connection request to the VPN server for verification.
- User data is encrypted (also known as tunneled) before it is sent to the VPN server. This delivery process takes place over the Internet.
- The VPN server decrypts the received data and forwards it to the intended destination.
- The user’s device then receives the decrypted data. This means that the user has securely accessed the Internet.
- The above description is the general process and operation of a VPN. The details of the process itself can vary depending on the protocol used. Some types of protocols that are used are OpenVPN, PPTP, L2TP/IPSec.
