How does a VPN work?

A VPN encrypts your data and hides your IP address by sending your traffic through a VPN server before it reaches the internet. The encryption protects your data from snoopers and intrusive third parties, while the changed IP makes it seem like you’re visiting from the VPN server location rather than your home.

  1. Creates a secure connection

By connecting to the internet with a VPN, you establish a secure virtual tunnel between your device and the internet via a VPN server. This tunnel is then used to transfer all your internet traffic.

  1. Changes your IP address

Once your internet traffic goes through the VPN tunnel, your IP address changes. Instead of seeing your IP address, the websites and services you visit see the IP address of the VPN server.

  1. Encrypts your data

A VPN encrypts all your traffic to make sure the tunneling process is secure. The encryption hides your data under a code so that no third parties can access your sensitive information.

Understanding the basics of a VPN

What is a VPN tunnel?

What is a VPN tunnel?

A VPN tunnel is a secure connection between your device and the internet. Tunneling relies on encapsulation, which hides VPN communications on the public internet. So, if someone were to check your internet connection, they’d see that you are using a VPN, but not what you’re doing.

Want to hide the fact that you’re using a VPN on top of protecting your activity? You can use our obfuscated servers for that extra bit of privacy.

What is a VPN server?

A VPN server is just a standard internet server configured with VPN software. Your traffic is first routed through the server before it reaches the internet. This allows the VPN to hide your actual IP address and keep your data protected from snoopers.

What is an IP address?

What is an IP address?

An Internet Protocol (IP) address is a digital label used to achieve communication between networks. It’s used to identify you and your location in the network. A VPN hides your IP address, which prevents websites from gathering information about you. 

What is encryption?

VPNs use encryption to encode and secure your data. The VPN client and server generate a key when you connect to a VPN. The key is used to encode and decode your data every time it travels through an encrypted tunnel. No third parties have the key, so your encrypted data looks gibberish if they try to intercept your connection.

The security of encryption depends on the cipher that’s used. The AES 256-bit cipher is considered the best encryption algorithm and is used by the US government, the NSA, and reliable VPN service providers, including Surfshark.

What does a VPN hide?

A VPN hides and encrypts all your internet traffic. This includes your IP address, location, the websites you visit, and what you do on those websites. That said, a VPN cannot hide any information that you choose to show, such as social media posts or the information you voluntarily provide to register on websites.

Does a VPN make you fully anonymous?

No, a VPN does not make you totally anonymous. In fact, there is no way you can be fully anonymous online. However, you can significantly enhance your online privacy by using a VPN. While it doesn’t hide all the traces of your internet use, it encrypts your data, hides your IP, and protects you from trackers.

How secure is a VPN?

A VPN is very secure if it uses the best encryption and connection protocols, as Surfshark does. 

Most security measures are made to be too tedious to crack. Depending on the computer used, an encrypted session could take millions of years to decode. Needless to say, that’s far longer than any VPN session lasts. 

Even if someone managed to crack the encryption, many VPN providers like Surfshark have implemented something called Perfect Forward Secrecy (PFS). This means that a VPN client generates a new key every 7 minutes or so. This keeps your private data out of bad actors’ reach.

What are the types of VPNs?

While there is no hard-and-fast ISO-approved classification of VPN types, here are the currently agreed-upon definitions:

Remote access VPN

Remote access VPN

A remote access VPN allows the user to connect to a remote network securely. It helps simulate the level of security you’d have by connecting to that network from a safe location. Since work-from-home has become more common, this VPN type has seen a huge rise in popularity as it allows employees to establish a secure connection to a remote work network.

Site-to-site VPN

Site-to-site VPN

Site-to-site VPNs connect intranets to networks. This is useful for large companies with offices all over the world. While the office intranets are spread out all over the place, the site-to-site VPN connects them into a single, seamless network that employees can use without having to configure and connect to other networks.

Personal VPN

Personal VPN

Personal VPNs are meant for individual users. Instead of connecting to a different network, it connects users to a VPN server. When a user accesses a website or service with a personal VPN, their traffic looks like it’s coming from the VPN server, not their home network. Surfshark and most other popular VPNs are personal VPNs.

VPN protocols

VPN protocols determine how your VPN connections work from start to finish. On top of that, they can have an impact on the speed and security of your VPN connection. Quite a few VPN protocols exist, but to make it easier, here are some of the best ones to use right now:

OpenVPN 

OpenVPN 

OpenVPN is an open-source VPN protocol. It’s fast, secure, and compatible with many routers. Because it is open-sourced, its code has been examined through and through by cybersecurity experts worldwide. It’s a trusted workhorse but tends to perform worse than IKEV2 and WireGuard.

Available on: Windows, macOS, Android, iOS, Linux, and BSD.

Supported by Surfshark: Yes 

WireGuard®

WireGuard®

WireGuard® is a relatively new protocol built to surpass OpenVPN and IPSec in power use and performance with only 4,000 lines of code. As it stands, WireGuard is the fastest VPN protocol available today.

Available on: Windows, macOS, Android, iOS, FreeBSD, NetBSD, OpenBSD, and others.

Supported by Surfshark: Yes

IKEv2/IPSec

IKEv2/IPSec

Internet Key Exchange version 2 (IKEv2) is on par with WireGuard’s quality. It can outperform other protocols in terms of speed when switching networks and at shorter distance connections, making it popular among mobile users.

Available on: macOS, Android, iOS, Linux, Blackberry, Unix, and others.

Supported by Surfshark: Yes

PPTP and LT2P/IPSec

PPTP and LT2P/IPSec

Both are severely outdated tunneling protocols, and it’s better to avoid them. While they’re relatively fast, they can’t offer the security or reliability of OpenVPN, IKEv2, or WireGuard.

Available on: Windows, macOS, Android, and iOS.

Supported by Surfshark: No

SSTP

SSTP

SSTP is a tunneling protocol rather than a VPN protocol. This means that it lacks the functionality of OpenVPN, IKEv2, and WireGuard. While considered relatively safe and easy to use, its code was never audited, and it has issues working on other operating systems like Mac OS.

Available on: Windows, Linux, and BSD.

Supported by Surfshark: No

Shadowsocks

Shadowsocks

Shadowsocks is not a VPN protocol but a tunneling proxy. However, it can run as a protocol on VPN clients. It was created for the sole purpose of bypassing The Great Firewall of China. It is fast, hard to detect, and can be used to skirt government-imposed censorship.

Available on: Windows, macOS, Android, iOS, and Linux.

Supported by Surfshark: No

How to pick a VPN service

Now that you’ve decided you need a VPN, you should know what to look for when choosing a provider. Here are the essential things to look out for:

Server coverage

Server coverage

A strong VPN provider should have good worldwide VPN server coverage. This will give you more locations to choose from and will decrease server load.

VPN encryption

VPN encryption

A secure VPN encryption algorithm is essential. Make sure to look for the AES-256 cipher — the current standard in the industry.

Server load

Server load

If there aren’t enough servers to balance the user load, connection speeds will suffer and become slow.

VPN protocols

VPN protocols

Protocols are vital to a VPN’s security, and you can use different ones based on your preference. Look for services that offer OpenVPN, IKEv2, or WireGuard, as they’re some of the best options in the VPN game right now.

MultiHop

MultiHop

MultiHop is a VPN feature that directs your traffic through several servers simultaneously. This provides you with even more protection but slows the connection down. Using it is not essential, but it can give your online security an extra kick.

Obfuscated VPN servers

Obfuscated VPN servers

When you connect to an obfuscated server, your traffic seems like regular internet traffic. This helps to bypass VPN blockers and protects you from censorship by oppressive governments.

Device support

Device support

Before purchasing a VPN, make sure it supports the device you wish to secure. Surfshark supports all major platforms, such as iOS, macOS, Android, Windows, Linux, and more.

RAM-only servers

RAM-only servers

RAM-only servers are becoming a staple for any good VPN service. When running on RAM, servers automatically wipe all the data whenever they’re turned off.

The Privacy Policy

The Privacy Policy

A solid Privacy Policy is one of the most important parts of any VPN service. It’s an immediate red flag if your VPN provider does not have a Privacy Policy or if they’re logging sensitive information without any stated reason.

FAQ

How do I test if a VPN is working?

The easiest way to check whether your VPN is working is by performing a DNS leak check. Turn off the VPN, perform the test, and check your IP. After that, connect to a VPN and do the same test again. If your VPN works, the IP addresses you get should be different.

And if you want a more detailed description, check out this blog post for more ways to see if your VPN is working.

What devices are VPNs compatible with?

Device compatibility always depends on the VPN provider. Surfshark supports apps and plugins on most computers, mobile devices, smart TVs, and consoles.

What is a no-logging or a no-logs VPN?

No logging means handling user data without keeping any logs or records of their online activity. In short, a no-logs VPN will not collect the following information about your internet activity:

  • Your IP address;
  • Your network traffic;
  • Your browsing history;
  • Your bandwidth information;
  • Connection timestamps;
  • Session information.

Are VPNs legal?

The short answer is yes — VPNs are legal in most countries. However, it is still against the law to use a VPN for illegal activities.

Some countries ban VPNs for political and legislative purposes like internet access control and stunting freedom of speech. Yet, most countries do not forbid nor restrict their use.

What is a VPN web browser? Can I use it?

A VPN browser has a built-in VPN protocol that protects the user’s browser resources. Not everything that is advertised as a VPN browser is one. Some are just privacy browsers.

Can a VPN make my internet connection faster?

In some cases, yes. If you’re streaming or downloading something, your ISP (Internet Service Provider) may throttle, i.e., slow down your internet connection. They do this to save on and distribute bandwidth across their internet users. But since a VPN hides your traffic, your internet service provider lacks the information to throttle you.

However, in most other cases, a VPN will not make your connection faster because it adds extra steps to accompany your connection. By default, the prolonged process may slow your connection, but it will hardly be noticeable.

How much does a VPN cost?

The price of a VPN depends on the provider and the subscription period. Shorter subscriptions tend to be more expensive and are usually in the $12-15/month range. Longer subscriptions are much cheaper, so if you decide to go for a 2-year plan, you can get a premium VPN for as little as $2-4/month.

Can I use a free VPN?

You can, but you shouldn’t. 

A VPN uses servers to reroute your information. Thousands of these servers are scattered worldwide, costing money to set up and maintain. The same goes for developers and everyone else who works to keep the VPN functioning.

In other words — VPN services are expensive to maintain, so they all have to make money in one way or another. There are three ways to do this:

  1. Setting up a subscription.
  2. Bombarding the user with ads.
  3. Collecting and selling the user’s information.

A “free” VPN often does numbers two and three simultaneously. So, be careful when choosing a VPN service provider!

Is a VPN safe?

Yes, a VPN is safe as long as it’s not a free VPN. Premium VPNs tend to have AES-256 encryption, which is considered to be the best option today. On top of that, they use modern VPN protocols without known vulnerabilities to ensure a secure connection.

What happens if you don't use a VPN?

When not using a VPN, you are easier to track, the ISP can get your internet browsing history, and you may experience bandwidth throttling. 

If you want in-depth information, check out our article on why you should use a VPN.

What makes your data valuable?

Your Internet Service Provider (ISP) and websites can monitor, log, and later sell the information connected to your browsing, e-shopping, and other habits. This data is valuable to ad brokers and service providers because it reveals patterns in your actions, such as likes, hobbies, and interests. They can later use this to make product offers you’re more likely to buy.

What does VPN mean?

VPN stands for Virtual Private Network. The VPN meaning is related to a secure, encrypted connection to a server or network. While there are several types of VPNs, the most common is a VPN client that users can use to connect to a VPN server without any need for a laborsome, technical setup.
