What Is a VPN? [Beginners Guide]

Have you ever worried about online privacy or noticed “Your region is restricted” when streaming your favorite Netflix series?

If any of this sounds familiar, a simple and robust solution is a VPN.

Wondering “what is a VPN” and why it’s a must-have tool? This article will summarize everything you need about VPNs and give you the top VPN recommendations to enhance your online experience.

What is a VPN?

A VPN, or Virtual Private Network, is a secure online tool that creates a private tunnel for your online activities. It establishes a protected connection between your device and a remote server, encrypting your data and ensuring your internet use remains private.

When you browse the web without a VPN, your searches, IP address, and online activities may be tracked and stored. However, with a VPN, your IP address is hidden and your online information remains secure, protecting you from prying eyes and preserving your privacy.

Why You Should Use a VPN?

1. Protect your privacy: When you browse the internet, your data, such as the websites you visit and your location, can be tracked by websites, advertisers, and even hackers. A VPN hides your IP address and encrypts your data, ensuring your online activities remain private.
2. Stay safe on public Wi-Fi: Public Wi-Fi networks in coffee shops, airports, and hotels are convenient but not very secure. A VPN prevents potential hackers from trying to steal sensitive information like your passwords or credit card details.
3. Access restricted content: Have you ever encountered “not available in your region”? VPNs allow you to connect to servers in different countries, bypassing geographic restrictions and allowing you to access any content.
4. Ensure remote work security: For those who work remotely, VPNs provide a secure connection to the company network, protecting sensitive business data from leaks or cyberattacks.
5. Avoid bandwidth throttling: Internet service providers (ISPs) sometimes limit your download or upload speeds. With a VPN, your online traffic will be encrypted, making it more difficult for ISPs to throttle your speed.
6. Enhanced online shopping and travel deals: Prices on flights, hotels, and even products on Amazon can vary depending on your location. A VPN can help you find better deals.

In short, a VPN is a tool that makes your internet use more secure, private, and free from restrictions.

How Does a VPN Work?

VPN (Virtual Private Network) is a very professional security network tool. Now, you will understand how VPN works:

1. When you connect to a VPN, your device establishes a secure “tunnel” to a remote server operated by the VPN provider. This tunnel is encrypted and no one can read it.

2. VPN changes your IP address by assigning you an IP address from its server, making it look like you are browsing from another location.

For example:

• Without VPN: You are browsing the web from your real IP address, such as New York.
• With VPN: Even if you are in New York, it may look like you are browsing from Tokyo.

3. VPN encrypts your information (such as browsing history, passwords, or messages) into unreadable code. Even if hackers or snoopers intercept your data, it is just gibberish to them.

4. Once your data is encrypted, it is sent to the remote VPN server before it reaches the Internet. You can understand it as: instead of visiting the website directly, you ask the VPN to transmit the information back to you.

Overall, whenever you connect to the Internet using a VPN, your data is sent to the VPN. The VPN then takes you to the website you want to visit and securely sends back any information you need.

What Can You Do With a VPN?

Well, you already know what a VPN is. You might wonder, “What can you do with a VPN”.

Check if any of these situations sound familiar:

• You’re using public WiFi at a cafe, unaware that someone might be spying on your browsing history and private conversations.
• While traveling abroad, you may be shocked that your usual social media platforms are inaccessible.
• You’re in the middle of an intense game of “PUBG” with friends, but opponents eliminate you due to lag and disconnections caused by network issues.
• You want to watch a globally popular Netflix series, but it’s unavailable in your region.
• While shopping online, you discover that the price of the same product is higher for you than for a friend.

That sounds frustrating, doesn’t it? Don’t worry, all these problems can be solved with a VPN!

• Enhanced security: The VPN protects your data from disclosure, keeping your browsing history and private information safe.
• Freedom to Browse Social Media: No matter where you are, a VPN lets you easily access various social platforms.
• Uninterrupted Gaming: With a VPN, you can fight against DDoS attacks and bandwidth throttling, enjoying a smoother gaming experience without lags and frequent disconnections.
• Access Global Entertainment: Breakthrough regional restrictions with a VPN to watch any TV show or movie you like.
• Smart Price Comparisons: A VPN helps you see the real prices of products.

Now that you know what a VPN can do for you, do you think having one is necessary? Let’s take a look at the types of VPNs!

What are the Types of VPNs?

1. Personal VPN: A personal VPN protects your personal information from prying eyes and keeps your online activities private when you connect to a VPN server. Whether in a coffee shop or traveling abroad, a personal VPN will keep your online activities safe.

2. Site-to-site VPN: Site-to-site VPN is mainly suitable for businesses with offices in different locations. This VPN creates a single, secure network that allows employees to share resources and data across locations easily. It is extremely helpful for remote working as it allows employees to access everything they need.

3. Remote access VPN: Remote access VPNs are great for people who work outside of the office, such as at home or at a coffee shop. It establishes a secure connection to your work or home network so you can securely access files and resources.

What are the Encryption Protocols of VPN?

• PPTP (Point-to-Point Tunneling Protocol): One of the earliest protocols out there. It’s super easy to set up and really fast, but it’s not the most secure. Best for when you need a quick connection for things like casual social media browsing where high security isn’t crucial.
• L2TP/IPSec (Layer 2 Tunneling Protocol/Internet Protocol Security): Safer than PPTP because it encrypts your data. It offers a good balance of speed and security and works well on smartphones. It’s commonly used for remote office work because of its decent security and broad device support.
• OpenVPN: This is an open-source protocol that offers a lot of customization and strong security. It’s perfect for those who need top-notch security, like when you’re handling financial transactions or transferring sensitive data.
• SSTP (Secure Socket Tunneling Protocol): Mostly used on Windows, SSTP can get through most firewalls and offers robust encryption and security. It’s ideal for Windows users who need to access restricted sites, especially in highly censored areas.
• IKEv2/IPSec (Internet Key Exchange version 2/Internet Protocol Security): Great for mobile devices because it supports automatic reconnection if your connection drops. It offers high security and stable connections, making it ideal for people who often switch between networks, like business travelers needing to keep their VPN connection stable as they move around.

What is the Best VPN?

Now, let’s take a look at what features the bestVPN needs:

• Server network: An extensive server network must allow you to change “sites” at any time and enjoy fast and smooth connections.
• Encryption technology: Ensure that the VPN uses industry-standard encryption technology to provide strong protection for data transmission.
• Supported protocols: A good VPN will provide a variety of protocol options, such as OpenVPN and IKEv2. This allows users to choose the connection method that best suits their needs.
• Stealth function (obfuscated server): In an environment with strict network censorship, the server can help VPN traffic disguise itself as ordinary web page traffic.
• Device compatibility: A good VPN should support multiple devices and operating systems, protecting all your devices.
• Privacy policy: A clear and transparent privacy policy is an essential indicator of VPN service quality, ensuring that the provider promises not to record user activity logs.
