A simple beginner guide explaining what a VPN is, how it works, what it hides, what it does not protect you from, and how Indian users should evaluate VPNs for privacy, streaming, travel, public Wi-Fi, and pricing.
Quick Verdict
A VPN, or Virtual Private Network, is a tool that creates an encrypted connection between your device and a VPN server.
In simple words, it can hide your real IP address from websites, reduce exposure on public Wi-Fi, and let your internet traffic appear as if it is coming from another location.
But a VPN is not magic.
It does not make you fully anonymous. It does not protect you from every scam, phishing link, malware file, or bad privacy habit. It does not make illegal activity legal.
For Indian users, the right way to understand a VPN is simple:
A VPN is useful when you need better privacy on unsafe networks, location-based access, or an extra layer of protection. But it should be judged by testing, not by marketing claims.

What is a VPN?
VPN stands for Virtual Private Network.
A VPN creates a secure connection between your device and a VPN server.
Without a VPN, your internet traffic usually travels through your internet service provider first, then reaches the website or app you are using.
With a VPN, your traffic first goes through the VPN server.
The website you visit sees the VPN server’s IP address instead of your normal IP address.
That is the basic idea.
Simple Example
Imagine you are sitting in Delhi and browsing a website normally.
Without VPN:
Your phone/laptop → Your internet provider → Website
With VPN:
Your phone/laptop → VPN server → Website
The website sees the VPN server location, not your normal internet connection location.
So if you connect to a Singapore VPN server, websites may see traffic coming from Singapore.
If you connect to a US VPN server, websites may see traffic coming from the US.
This is why VPNs are often used for location-based access, streaming, travel, public Wi-Fi safety, and privacy improvement.
What Does a VPN Actually Do?
A VPN mainly does three things.
These three things create most VPN benefits.
But they also create confusion.
A VPN improves privacy in specific ways.
It does not solve every online safety problem.
What Does a VPN Hide?
A VPN can hide your real IP address from websites and apps you visit.
It can also reduce what your internet provider can see about your browsing activity.
For example, your internet provider may see that you are connected to a VPN server, but not necessarily the exact websites you visit through that encrypted VPN tunnel.
However, this depends on the VPN setup, DNS handling, browser behavior, app behavior, and whether leaks occur.
That is why benchmarksutra tests VPNs for DNS leaks, WebRTC leaks, and kill switch performance.

What a VPN Can Help With
A VPN can be useful for:
A VPN is useful when the use case is clear.
It is not useful when bought blindly because a website says “80% off today”.
If you are choosing a VPN by use case, start here:
Best VPN India: Complete Guide
What a VPN Does Not Do
A VPN does not make you completely safe online.
It does not protect you from everything.
The biggest mistake is treating VPN as a magic safety button.
It is a tool.
You still need safe browsing habits.
Is VPN Legal in India?
Using a VPN is not automatically illegal in India.
But illegal activity remains illegal even if done through a VPN.
The India-specific issue is the CERT-In 2022 cyber security directions.
CERT-In’s April 2022 directions included VPN service providers among entities required to maintain certain subscriber/customer information for five years or longer after cancellation or withdrawal of registration.
Official source:
https://www.cert-in.org.in/PDF/CERT-In_Directions_70B_28.04.2022.pdf
This rule changed how several global VPN providers handled India servers.
Many VPN companies moved away from physical India servers and started offering virtual India servers instead.
That is why Indian users should check whether a VPN offers:
Physical India servers
Virtual India servers
India IP availability
Clear official explanation of India server status
Nearby Asian servers
For broader VPN buying guidance, read:
Best VPN India: Complete Guide
Physical India Server vs Virtual India Server
This point matters for Indian VPN buyers.
A virtual India server is not automatically bad.
In some cases, it may be a deliberate choice by VPN providers after India’s CERT-In directions.
But it must be disclosed clearly.
If a VPN says “India server available”, check whether it means physical India server or virtual India server.
Do not assume.
How Does a VPN Work?
A VPN works by creating an encrypted tunnel between your device and a VPN server.
Here is the simplified flow:
You open the VPN app.
You choose a server location.
The VPN app creates an encrypted connection.
Your internet traffic goes through the VPN server.
Websites see the VPN server IP instead of your usual IP.
This is why VPNs are used to change visible location.
But the VPN provider itself becomes important.
If you route your traffic through a VPN, you are shifting some trust from your internet provider to the VPN provider.
That is why privacy policy, audit status, jurisdiction, and past incidents matter.
A VPN with weak privacy practices is not automatically better than no VPN.
Why Do People Use VPNs?
People use VPNs for different reasons.
The right VPN depends on the reason.
1. VPN for Public Wi-Fi
Public Wi-Fi is one of the easiest use cases to understand.
If you use Wi-Fi at:
Airport
Hotel
Cafe
College
Coworking space
Railway station
Public library
A VPN can add a useful layer of protection.
It can reduce exposure on unsafe or poorly secured networks.
For this use case, look for:
A public Wi-Fi VPN does not need to be the most expensive VPN.
But it should be reliable.
2. VPN for Streaming
Streaming is one of the most common VPN use cases.
People use VPNs to access different content libraries or services while travelling.
But streaming is not guaranteed.
Platforms can block VPN servers.
A VPN that works with Netflix today may fail later.
For streaming, check:
Do not buy a VPN only because it says “works with Netflix”.
Buy only after checking recent tests.
3. VPN for Privacy
Privacy users need stricter evaluation.
A VPN should not be trusted only because it says “no logs” on the homepage.
For privacy, check:
Privacy claims need evidence.
If you want to understand our privacy scoring, read:
benchmarksutra VPN Testing Methodology
4. VPN for Travel
Travellers may use VPNs when they are outside India.
Common travel use cases include:
Safer hotel Wi-Fi
India IP access
Indian OTT access where permitted
Access to accounts while abroad
Safer browsing on airport Wi-Fi
Region-specific browsing
But apps and websites may behave differently depending on:
Country
Device
App version
VPN server
Security checks
Account history
So benchmarksutra does not make blanket claims like:
This VPN will always work with Indian banking apps abroad.
A better claim is:
This VPN worked during our test on the stated device and date, but app behavior can change.

5. VPN for Torrenting
Torrenting is a sensitive topic.
A VPN can hide your IP from peers and reduce exposure, but it does not make illegal downloads legal.
For torrenting, check:
Do not use a VPN as an excuse for illegal activity.
Evaluate only the technical privacy and performance features.

DNS Leak Test Explained
6. VPN for Remote Work
Remote workers may use VPNs on hotel Wi-Fi, cafe Wi-Fi, airport Wi-Fi, or shared networks.
But there is an important distinction:
A consumer VPN is not the same as a company VPN.
If your company provides a corporate VPN, use that for company systems.
A consumer VPN is more useful for general browsing, public Wi-Fi protection, and personal privacy.
For remote work, check:
Remote workers should prioritize reliability over cheap pricing.
7. VPN for Gaming
A VPN does not automatically improve gaming.
In many cases, it can increase ping because traffic travels through an extra server.
A VPN may help only in specific cases, such as:
Bad ISP routing
Region-specific access
DDoS protection for some users
Testing servers from other locations
For gaming, check:
Do not buy a VPN for gaming unless the review shows actual ping and jitter tests.
Marketing claims are not enough.
Free VPN vs Paid VPN
Free VPNs are tempting.
But free VPNs often come with trade-offs.
Common issues include:
Data limits
Speed limits
Fewer servers
Ads
Weak streaming access
Unclear privacy policy
No useful support
Aggressive tracking concerns
Poor app experience
That does not mean every free VPN is automatically unsafe.
But you should ask:
If I am not paying with money, what am I paying with?
For privacy-sensitive users, a weak free VPN can be worse than no VPN.

VPN vs Proxy vs Tor
Beginners often confuse VPN, proxy, and Tor.
They are not the same.
Most normal users should understand VPN first.
Proxy and Tor are different tools for different needs.
Coming soon on benchmarksutra:

What Does VPN Hide?
Is Tor Better Than VPN?
Does a VPN Make You Anonymous?
No.
A VPN improves privacy in specific ways, but it does not make you fully anonymous.
You can still be tracked by:
Logged-in accounts
Cookies
Browser fingerprinting
Apps
Payment records
Device identifiers
Malware
Phishing links
Websites where you enter personal details
Example:
If you log in to your Google account while using a VPN, Google still knows it is your account.
The VPN may hide your IP from websites, but it does not erase your identity from services where you are logged in.
This is why “VPN = anonymous” is a bad claim.
Does a VPN Protect You from Hackers?
Partly, in specific cases.
A VPN can help protect your connection on unsafe public Wi-Fi by encrypting traffic between your device and the VPN server.
But it does not protect you from everything.
A VPN will not automatically stop:
Phishing websites
Fake banking pages
Malware downloads
Scam calls
Fraud apps
Weak passwords
OTP scams
Social engineering
Think of VPN as one layer of protection.
Not the whole security system.
Does a VPN Increase Internet Speed?
Usually, no.
A VPN can sometimes improve routing in rare cases, but most of the time it may slightly reduce speed because traffic takes an extra route.
Speed depends on:
Your base internet connection
VPN server distance
VPN protocol
Server load
Device performance
Time of day
ISP routing
A good VPN should reduce speed as little as possible.
But you should not expect every VPN to make your internet faster.

Final Verdict
A VPN is a useful privacy and access tool, but it is not a magic shield.
It can hide your real IP from websites, encrypt your connection through a VPN tunnel, and help with public Wi-Fi, streaming, travel, remote work, and privacy use cases.
But it does not make you fully anonymous.
It does not protect you from every scam.
It does not guarantee streaming access forever.
It does not make illegal activity legal.
For Indian users, the best approach is simple:
Understand what a VPN actually does. Decide your use case. Check India server status, privacy policy, speed, streaming tests, refund terms, and renewal price. Then choose.
