VPN is an abbreviation for Virtual Private Network. A Virtual Private Network allows to establish a safe and encrypted connection to access the public internet securely. VPN hides the user’s online identity by real-time encryption of the traffic sent or received over the internet. This makes a VPN more secure than a private WiFi hotspot.
How Does VPN Work?
In order to understand how VPN works, let us first understand the path followed by data when a user accesses the internet.
When a user sends a request to a website over internet, the data is sent or received via Internet Service Provider (ISP). Any request sent by the user is first redirected to the ISP server and then transmitted to the online service or website. Similarly, data sent by the website in response to the user request is first sent to the ISP server, which then sends it to the user. Thus ISP server has details pertaining to user’s identity, browsing history, online communications, etc. Hackers can also gain access to these details by targeting ISP servers.
VPN acts as a tunnel that bypasses ISP server. When user connects to internet via VPN, the traffic between the user and internet is sent via secure server of the VPN instead of the ISP server. VPN server acts as source server for the user. This can be understood in a stepwise manner.
- User sends data to a website.
- The data is received by the VPN server.
- VPN server sends the data to internet.
- Traffic received from internet is received by VPN.
- VPN then serves the traffic to user.
As a result of the process, the user has no direct interaction with the internet. This keeps user’s identity and internet surfing history private. Additionally, VPN encrypts the traffic to ensure further security in case the server is hacked.
What Are The Uses Of VPN?
VPN can be used for a wide array of purposes:
- Staying Anonymous Online: ISPs can keep an eye on your online activity including services or products you search for. This information holds high value on dark web. Using a VPN for online activity helps in keeping your credentials and online activity hidden and secured.
- Ensure Security On Public WiFi: Public WiFi are not secured and lack data security configurations. Low security makes it easier for hackers to compromise the WiFi and eavesdrop on the traffic moving across the server. Using VPN when accessing internet over public WiFi helps in ensuring data and credentials security.
- Data Security: Comparable to ISPs, many apps collect user data and sell it to marketing agencies. Using a VPN prevents apps from attributing data to user’s IP address, thus, ensuring data security.
- Content Access: Content streaming platforms might publish some content for targeted locations only. For example, some shows might not stream outside US. However, users can use a VPN to mask their location and access geo-blocked content irrespective of their physical location.
