What is a VPN? How it Works & How to Use a VPN (2025)

Short for Virtual Private Network, a VPN keeps you safe and anonymous online. It creates a secure tunnel between you and the internet, keeping your identity and online activity hidden from hackers and other prying eyes. Also, VPNs help overcome online censorship and ensure you can access your local platforms no matter where you are.

While they can seem technical, you don’t need to be an expert to understand how VPNs work and why you need one. This guide will teach you everything you need to know about VPNs — from how they work to how you can pick the best one for your needs.

I’ve also listed the most beginner-friendly VPNs, but ExpressVPN is the best overall choice. It’s easy to use, offers lightning-fast speeds, and maintains unbreakable security. It’s got a 30*-day money-back guarantee, so if you’re unsatisfied, you can easily claim a full refund. Editor’s Note: Transparency is one of our core values at WizCase, so you should know we are in the same ownership group as ExpressVPN. However, this does not affect our review process, as we adhere to a strict testing methodology.

Try ExpressVPN risk-free

What is a VPN and How Do VPNs Work?

VPNs are critical security tools that enhance online privacy and safety. Without a VPN, third parties can easily intercept and view your online activity, including browsing history, downloaded files, online banking details, and passwords.

Third parties can see what you’re doing because all your activity is linked to your IP (Internet Protocol) address. Your IP address even reveals your physical location, making it simple to track you down. Simply put, it’s like sending postcards through the mail — anyone can read the message and see your name and address.

Connecting to a VPN encrypts your activity. This means no one can see what you’re doing, and anyone who tries to intercept your traffic will only see gibberish. VPNs also mask your IP address and identifying information, meaning no one can see who you are.

Using a VPN is like sending highly secure messages that only the recipient can access. These messages contain no sender information, and anyone trying to intercept them will see a scrambled mess of encrypted data.

Additionally, when connected to a VPN, the website or service you are accessing sees the VPN server as the source of your data, providing complete freedom to explore the internet without any restrictions.

Do You Really Need a VPN?

Yes, you need a VPN to safely and freely access the internet. Here’s a list of reasons why consumers currently use VPNs:

Let’s take a closer look at some of the most popular reasons for using a VPN and how VPNs enhance safety and improve your online experience.

Security and Privacy

Many networks, like public WiFi and hotspots, aren’t secure because they don’t encrypt your traffic. Hackers know this and target these networks to steal user information, like credit card details, passwords, and more. ISPs can also monitor your home network activity and share it with the government. Using a VPN encrypts all your activity to maintain safety.

Bypass Blocks, Restrictions, Censorship, and Firewalls

The best VPNs are effective at circumventing network blocks, which commonly occur in the following forms:

• Government censorship. Various countries censor the internet because certain content doesn’t align with local political or religious beliefs.
• Local network restrictions. Local administrators for networks like schools and offices block access to sites and services considered inappropriate.
• Location restrictions. Some online services (like Hulu and BBC iPlayer) impose restrictions depending on your geographical location to avoid copyright issues.

If you’re experiencing these restrictions, using a VPN can help access the content you want to see. Note that it’s against most platforms’ Terms of Service to use a VPN to bypass geoblocks. This can be considered copyright infringement, and my team and I don’t condone any illegal activity.

You should also be aware that circumventing government-sponsored censorship can break local laws, so exercise caution when using a VPN. Just because your activities are completely anonymous doesn’t give you the right to do anything illegal.

Torrent Files Safely and Anonymously

Torrenting is risky, as P2P connections expose your real location to every peer connected to the same files. This leaves you vulnerable to hackers and identity theft. Using a VPN hides your IP address, keeping you safe and anonymous while torrenting. There’s also the added benefit of avoiding throttling, as your ISP won’t see that you’re downloading torrents.

Improve Your Internet Connection and Speeds

ISPs can deliberately slow down your internet connection (if they’re legally allowed), which is called “throttling.” VPNs help prevent this by keeping ISPs from seeing your torrenting or streaming activity. Keep in mind that if you’re being throttled because of a data cap, a VPN can’t help with this.

Besides improving speeds, VPNs also improve your ping and let you choose different servers while gaming. This improves your experience if you play Call of Duty: Warzone or other games with friends from different countries.

Are VPNs Safe? How to Choose a Secure VPN in 2025

It’s not always clear which VPN features are worthwhile and which are just marketing gimmicks. As someone who extensively tests and uses VPNs, I consider the following criteria most critical when picking one.

Strong Encryption and Connection Protocols

Securing your connection is among the key reasons for using a VPN, so look for one that provides reliable security. Pick a VPN with AES 256-bit encryption (the industry standard) and look for VPNs with secure protocols like OpenVPN, which is widely used and considered the safest. Proprietary protocols like ExpressVPN’s Lightway are also solid options.

Of course, the best protocol may change based on your requirements. Below are the most common protocols:

• OpenVPN: The most popular open-source protocol supported by almost every VPN and widely regarded as the most secure option.
• WireGuard: It has significantly fewer lines of code than OpenVPN, making it much faster without compromising security.
• IKEv2: A fast and secure protocol that’s popular with mobile apps. However, it isn’t open source and can’t be audited.
• SSTP: A less popular protocol that mostly works on Windows. It’s good for bypassing firewalls but delivers average speeds.
• L2TP/IPSec: Outdated protocol that was commonly used on iPhones — best to avoid.
• PPTP: This protocol isn’t fully secure and was previously cracked by the NSA.

No-Log Privacy Policy

It’s critical to get a VPN with a strict, independently audited no-logs policy. Otherwise, you risk the VPN storing your data and sharing it with parties like advertisers or governments. Additionally, it’s best to read the VPN’s privacy policy, as some might be storing your IP address, payment details, and connection time stamps while claiming to keep “zero logs.”

ExpressVPN is a good example, as its no-logs policy is proven. Turkish authorities physically seized an ExpressVPN server during a criminal investigation in 2017, but no identifying customer data was found. It’s also good to get a VPN based outside the 5/9/14 Eyes alliance (groups of countries that share surveillance data).

Fast Speeds

VPNs can slow down your connection, as the data gets encrypted and routed through another server before its destination. The difference in speed is barely noticeable with the best VPNs, meaning you won’t experience any lag.

Getting a VPN with a large server network also helps, as this reduces overcrowding and makes it easier to find a nearby server. Generally, your internet will be slower the further away a server is, as it takes longer for your data to get there.

Works With Streaming Services, Torrenting, Gaming, and More

The top VPNs can reliably access popular streaming platforms, download torrents, and play online games without issues. They mask your real location and IP address, letting you use your usual online services in restrictive countries.

Note that Netflix and many online platforms have to protect copyright agreements and use advanced detection methods to detect and block VPN IP addresses. So, if you want to use a VPN to access US Netflix or another platform, you should check beforehand if it’s capable.

Supports Multiple Devices and Platforms

The best VPNs support all major platforms, including Windows, macOS, iOS, Android, and Linux. Plus, these VPNs work on smart TVs, Amazon Fire Devices, routers, and other devices like gaming consoles, which don’t have native VPN app support.

Another thing to note before getting a VPN is how many simultaneous connections it allows. For instance, Private Internet Access (PIA) allows unlimited connections, letting you stay signed in and connected on all your devices.

24/7 Customer Support

It is critical to choose a service with 24/7 live chat, email, and other support channels, such as a detailed knowledge base. This ensures you can get help if something is wrong or if you have questions about using or configuring a certain VPN feature.

Value for Money and Money-Back Guarantee

Simply looking for the cheapest VPN may not be the best strategy. Instead, pick a VPN that offers all the above features at a reasonable value. One of the best ways to do this is by getting a long-term plan, as they offer large discounts. Alongside the price, get a VPN with a money-back guarantee, as this lets you try the service without risk before fully committing.

For instance, CyberGhost’s 2-year plan offers a massive 84% discount, and it gives you a 45-day money-back guarantee for all its long-term plans.

Are There Disadvantages to Using a VPN?

Of course, no VPN is perfect. There are some disadvantages you need to be aware of, but note that you can minimize most of them using one of 2025’s top VPNs:

• Slightly slower connection speeds. Since VPNs encrypt your data and increase the distance it travels, your connection may get slower.
• Your data may still leak. If the VPN connection is interrupted, your IP address may get exposed online. The best VPNs have kill switches to prevent this.
• Shady VPNs could log and sell your data. Many free VPNs profit by logging and selling your data to third parties, like advertisers. Make sure to check your app’s privacy policy and pick a reliable, trustworthy service.
• The best VPNs aren’t free. There are many free VPNs, but only paid VPNs offer reliable security and fast speeds. The good news is that many premium VPNs provide long-term plans that offer great value. Also, you can get a quality month-to-month VPN if you’re on a budget.
• VPNs aren’t legal worldwide. Countries like China, Russia, and Iraq either restrict or outright ban non-government-approved VPNs. If you wish to use one in these countries, ensure you download a VPN before traveling. Also, double-check local laws and regulations before connecting.

Common VPN Misconceptions

There are various misconceptions about VPNs floating around the internet, and the ones below are the most common.

VPNs Stop Viruses and Hackers

While they encrypt your traffic and improve online safety, VPNs aren’t built to defend against viruses and hack attempts. Even when you’re connected to one, it’s important to avoid unsafe links or dangerous emails that could download malicious attachments onto your system.

While some top VPNs like ExpressVPN can help avoid malicious websites, using a top antivirus is crucial to keep your system from getting infected.

VPNs Alone Can Stop Online Tracking

Although VPNs mask your IP address and keep you anonymous, modern websites use cookies, trackers, and browser fingerprinting tools to track you online. Logging into your Facebook or other social media accounts can also help websites track you, no matter how secure your VPN is.

Of course, some apps like ExpressVPN have tracker blockers to help prevent this, but it’s important to remember that VPNs alone can’t stop all online tracking.

How Much Do VPNs Cost?

The cost of a VPN depends on several factors, like the following:

• The VPN itself — tested and renowned services usually cost more.
• The length of your subscription.
• The number of servers.
• The variety of extra features, like split tunneling, ad and malware blockers, and obfuscation.

On average, a VPN costs $6-7/month, and it’s rare to see a VPN charging more than $10-12/month. Also, longer subscriptions let you get a VPN for a much lower monthly price. For instance, ExpressVPN’s 2-year plan costs $$4.994.99/month, while CyberGhost’s long-term 2-year plan costs $2.03/month.

Note that price isn’t the only factor to consider when buying a VPN. Ensure you get one with the security tools, server variety, and extra features you need.

Free VPN vs. Paid VPN: Which Is Better?

Premium VPNs are much better than free options, providing reliable security, faster speeds, and more servers. They’re worth the price because you can be sure they won’t sell your data to third parties or cause any interruptions while browsing, streaming, or downloading.

In contrast, free VPNs offer fewer servers, slower speeds, and limited security tools. Also, running a VPN network is expensive, meaning free VPN providers could collect and sell your data. If you really need a free option, it’s best to use a free VPN owned by a premium service. These “freemium” options have some restrictions, but they won’t compromise your privacy.

Besides the military-grade AES 256-bit encryption, ExpressVPN provides Advanced Protection to block ads, trackers, and malicious/inappropriate websites. You can easily enable these features by checking a few boxes in the app’s settings:

ExpressVPN also offers the following for added safety:

• Leak protection — stops IP address, DNS, and WebRTC leaks.
• Network Lock kill switch — blocks internet access to keep you anonymous if the VPN unexpectedly disconnects.
• Network-wide obfuscation — masks VPN traffic as regular traffic to avoid VPN detection technologies.
• TrustedServer technology — RAM-based servers that can’t store any data, as they’re wiped clean during reboots.
• Privacy-friendly jurisdiction — based in the British Virgin Islands, which is outside the 5/9/14 Eyes Alliance’s jurisdiction and doesn’t have data retention laws.

I found that ExpressVPN maintained the fastest connection speeds during tests. I only experienced a noticeable drop when connected to the long-distance server in Australia. On average, my connection speeds only dropped 15% compared to baseline values. Nonetheless, the connection was always fast enough for lag-free UHD streaming and fast downloads.

It costs a bit more than competitors, but ExpressVPN’s 2-year plan delivers great value, costing just $$4.994.99/month. Plus, all plans are backed by a 30*-day money-back guarantee. If you’re unsatisfied with the performance, you can contact support and ask for a full refund.

Key Features:

CyberGhost stands out by providing optimized servers for gaming, streaming, and torrenting. These servers are available worldwide and tested regularly, ensuring they always deliver a smooth connection. You can use the default servers as well, but the optimized options are the best for their designated activities.

During speed tests, CyberGhost maintained impressive connection speeds across all servers. It’s a bit slower than ExpressVPN, but both nearby and long-distance servers are fast enough for smooth UHD streaming without quality drops. The average speed drop was 25% compared to baseline values, with the optimized servers providing slightly better speeds.

For security, CyberGhost uses impenetrable AES 256-bit encryption. It also has the following tools to enhance protection:

• Malware blocker — blocks ads and pop-ups that link to malicious sites.
• WiFi protection — connects the VPN automatically when you join an unsecured network.
• NoSpy servers — owned and maintained by CyberGhost in its headquarters in Romania to prevent interference by third-party data center operators.
• Dedicated IP address — provides your own IP address to bypass CAPTCHAs and avoid blacklisting (available as a paid add-on).
• Security suite (Windows only) — includes a built-in antivirus that limits data collection and updates outdated apps to fix vulnerabilities.

You can get CyberGhost for $2.03/month with the 2-year plan, which is good value. The only thing I don’t like is its money-back guarantee is only 14 days for the monthly plan. Thankfully, all long-term plans have a generous 45-day-long money-back guarantee, letting you try CyberGhost risk-free.

Key Features:

PIA has easy-to-use and highly customizable security features, making it ideal for both beginners and advanced users. I especially like that you can hover over the “i” icon next to any of its configuration options to get more details.

Of course, PIA provides industry-standard protection to ensure you stay safe and anonymous online. Some of its key features include the following:

• Kill switch — disconnects the internet if the VPN connection is interrupted, ensuring you remain anonymous.
• Customizable encryption — provides AES 256-bit encryption for maximum security, but also allows switching to 128-bit when speed is more important.
• MACE — blocks ads, trackers, and malware while surfing the web.

One minor downside is that PIA is based in the US, within the 5 Eyes Alliance’s jurisdiction. Thankfully, there’s a strict no-logs policy to ensure it won’t have any user data to share, even if requested by the government.

PIA has an enormous network of 35,000+ servers in 91 countries, meaning you likely won’t connect to a slow and crowded server. During tests, I experienced an average drop of 35% compared to baseline connection speeds on various PIA servers. However, changing to 128-bit encryption and picking the WireGuard protocol helped improve this by roughly 7%.

I also like that PIA is one of the lowest-priced VPNs, costing just $2.03/month with the 2-year plan. Plus, you can try PIA risk-free, as it comes with a 30-day money-back guarantee, letting you ask for a full refund if you’re unhappy with it.

Easy Setup Guides: How to Install a VPN on Any Device

Installing a VPN is easy — just sign up for a service, install the app, and log in. Setups vary slightly depending on your device, but the overall process is roughly the same. The following step-by-step guides will help you set up a VPN on desktops, mobile devices, routers, and smart TVs.

Windows and Mac

Many VPNs offer native apps for Windows, macOS, and even Linux. The installation process is similar across all operating systems:

Android, iOS, Tablets, and Amazon Fire Stick

To ensure you get the money-back guarantee, always subscribe to VPNs directly from websites. Afterward, follow these steps:

Smart TVs, Roku, and Streaming Devices

Roku, most smart TVs, and streaming devices don’t support VPN apps natively. There are some exceptions, like ExpressVPN’s native Android TV app for Android-based smart TVs. In other cases, you can use a VPN on your smart TV by installing it on your router with the following steps:

You can also create a WiFi hotspot from your VPN-enabled computer and connect your smart TV to it. Another option is using Smart DNS, which changes the DNS server your TV uses to ensure access to your preferred platforms. However, this method isn’t as secure, as it doesn’t encrypt your connection.

Alternatives to VPNs

VPN Browser Extensions

VPN browser extensions work exclusively on your browser. If you use one, ensure you get it from a reliable VPN provider like ExpressVPN or CyberGhost, as many alternatives don’t encrypt your connection. Note that while they’re convenient to use, they aren’t the best overall options, as the VPN connection is limited to your browser, meaning your other activity isn’t safe.

Tor Browser

Tor (The Onion Router) browser is free and works like a regular browser. However, instead of sending your traffic directly to its destination, Tor routes it through different volunteer computers worldwide, also known as “nodes.” It’s relatively safe, but note that each node can see where your data is coming from and which node it’s going to.

You get almost complete anonymity with Tor, as it’s nearly impossible to trace your traffic’s route back to you. This makes it useful for surfing the dark web or communicating highly sensitive information. Unfortunately, the Tor network is extremely slow and is often blocked by ISPs, so the best solution is to use a VPN with Tor to prevent data leaks and keep your activity private.

Proxy Services

Proxy services pass your traffic through a third-party server, hiding your IP address. They improve anonymity and help access restricted websites. However, proxy servers provide limited security, as they don’t encrypt your traffic and lack features like leak protection or kill switches. Some might even tell the destination website you’re using a proxy, increasing the chances of your connection getting blocked.

All these alternatives have some uses, but using a premium VPN app is the best solution if you value security and privacy. It fully encrypts your connection, routes your traffic through secure servers, and maintains consistently fast connection speeds.

FAQs on VPNs

In Summary – What is a VPN and Why Do You Need One?

A VPN is security software that protects your data and online activities. Hackers are constantly finding more sophisticated ways to steal your data, but connecting to a VPN before going online significantly improves overall safety. You’ll also stay completely anonymous, helping claim back your right to privacy.

If you aren’t using one yet, you’ll be happy to know that VPNs are easy to use. Many of the top choices offer beginner-friendly apps and helpful setup guides to get you started. Of the best choices, I found that ExpressVPN is best for beginners because of its user-friendly friendly apps, superfast speeds, and impenetrable security.
