What is a VPN and what does it do?

A VPN is a service that establishes a secure, encrypted connection for your internet traffic, keeping your online activity hidden and protecting your privacy. The best VPNs have a no-log policy, bank-grade encryption, and a variety of servers around the world to help you browse anonymously.

A person uses a VPN to safely connect their device to a public Wi-Fi network.

Ever check your bank account or type in your credit card number to buy something online or while running errands? If you've done this without connecting to a virtual private network (VPN), you could have exposed your private information and browsing habits to cybercriminals or other snoops lurking on the same network.

Keep reading to learn how to stay securely connected on the go and how different types of VPNs can help keep your online sessions safe.

What is the definition of a VPN?

VPN stands for virtual private network—it’s technology that encrypts your data when you use the internet, scrambling it so that strangers on the same network can’t read it. A VPN creates a secure tunnel between your device and the internet to protect data during transmission. This secure tunnel helps VPNs disguise your IP address, mask your online activity (including links you click and files you download), and hide your physical location to help you access your favorite content.

A VPN gets its name because it embodies the following characteristics:

  • Virtual: Functions without physical cables and instead relies on digital pathways.
  • Private: Enhances online privacy by shielding data and browsing activity from snoops.
  • Networked: Establishes and maintains a connection between a device and a VPN server.

How do VPNs work?

VPNs encrypt the connection between your device and network, which helps strengthen online privacy and security. This is the process a VPN follows after you connect and begin your search:

  1. You enter a search query, visit a website, etc.
  2. The request passes through the VPN client on your device.
  3. The VPN client establishes a secure tunnel to the server, encrypting the data in transit.
  4. The VPN server forwards the request to the internet.
  5. The internet processes the request.
  6. The internet sends a result back to the VPN server through the secure tunnel.
  7. The VPN server responds to your device through the VPN client.
An overview of how VPNs work.

What does a VPN do and what are the benefits of using one?

VPN encryption capabilities help you browse anonymously, access content more freely, protect in-transit data, stop websites from tracking you, and protect your private information. Here are some more details about these VPN benefits:

  • Anonymous browsing: A no-log VPN can help hide your IP address from websites, cybercriminals, the government, and even your internet service provider (ISP).
  • Access content freely: VPNs are useful resources for journalists and travelers. They can help you access content that may be otherwise unavailable in your location.
  • Data protection: VPNs encrypt your internet traffic, making it safer to access financial accounts, private data, and other sensitive information online without others eavesdropping.
  • Less online tracking: Advertisers track much of your online activity using computer cookies. VPNs can help make it harder for them to track and monitor your activity by obscuring your IP address.
  • Protection on public Wi-Fi: Unsecured public Wi-Fi networks are notorious places for hackers to steal information; a VPN can help stop this by hiding your internet session activity so cybercriminals can’t see what you’re doing.

Who needs a VPN service and why?

A VPN can help provide an additional layer of online privacy, protection when sending and receiving data, and anonymity while browsing online. By disguising IP addresses and encrypting in-transit data, VPNs are useful tools for online banking, journalism, activism, accessing content while traveling, accessing the dark web, and more.

Here are some of the different types of people who use VPNs and why:

  1. General Users: Using a VPN helps enhance privacy and hide online activity. These benefits are especially helpful when using public Wi-Fi networks, ensuring that data while in transit is encrypted. 
  2. Businesses: Using a VPN offers businesses secure remote access for employees, helping to protect company data when employees are accessing networks remotely.
  3. Journalists, activists, and whistleblowers: Using a VPN helps ensure anonymity when accessing and sharing sensitive information online.
  4. Travelers: Using a VPN gives people a secure connection to access content when traveling, and it protects web traffic when using public Wi-Fi.
  5. Students: Using a VPN can help students access academic resources more easily.
  6. Gaming Enthusiasts: Using a VPN provides gamers access to global gaming servers and helps reduce the chances of an in-game interruption caused by a DDoS or other hacking attack.

People in different countries around the world can use a VPN to access content and social media platforms more freely. Beyond that, anyone can use a VPN to enhance their privacy when using public or airplane Wi-Fi, playing video games, browsing the dark web, working remotely, exchanging sensitive information online, or trying to avoid government surveillance.

FAQs about VPNs

Still have questions about VPNs? Here’s what you need to know.

What does a VPN protect you from?

A VPN can help protect you from eavesdropping on public Wi-Fi, identity theft, government surveillance, account takeovers, and unauthorized access to sensitive accounts.

Do VPNs make you anonymous?

VPNs help enhance your anonymity but can’t make you 100% untraceable. For starters, your internet service provider can’t see your activity when you use a VPN, but it can see the VPN’s IP address. And if there’s a DNS leak (security vulnerabilities that happen when your DNS request isn’t adequately concealed), any queries you enter online can get sent to the ISP’s servers.

Should I leave my VPN on all the time?

It’s up to you. You should turn your VPN on whenever you connect to public Wi-Fi. Beyond that, it’s your decision if you want to leave your VPN on all the time for continuous online security coverage. Just note that constant VPN use can slow down your internet.

What is a VPN on a phone?

A VPN on an iPhone or an Android phone is a mobile application that encrypts internet traffic, masks the device's IP address, and provides more secure and private online browsing through a virtual private network.

What is a VPN number?

A VPN number is a set of identifying numbers that maintain the VPN tunnel encryption and reroute traffic anonymously. Typically, a VPN number can refer to the following three possibilities:

  1. A specific server ID identification number that a VPN connection is associated with.
  2. A virtual phone number given by the VPN provider to the user.
  3. An internal IP address that is allocated to a mobile device when connected via VPN.

How do I install a VPN?

To install a VPN, download your provider’s VPN application, launch it, and log in. From there, you can connect to the server of your choice to secure your internet connection. If you have any issues, check to make sure your VPN is working properly.
