What is a VPN, and why use it?

Nowadays, it’s hard to understand the world without the internet. It has become a basic necessity for work and entertainment. But have you ever considered how secure your connection really is? Using public Wi-Fi or browsing from an unprotected device can expose you to risks, such as data theft or online activity tracking. Fortunately, as our online activity increased, protective tools evolved too. One of the most effective tools is a VPN. What is it? 

This technology has gained popularity in recent years, especially among users who value secure browsing. Besides protecting personal information, it also allows access to content without geographical restrictions. Sounds great, right? VPNs have become almost essential. Therefore, today we want to explain them. We’ll cover their benefits, how to use them, and the best options available. Join us to uncover the secrets of this powerful tool.

What is it and what is it used for?

When you hear VPN, you probably think about security or privacy. But do you really know what it means? VPN stands for Virtual Private Network. In simple terms, it’s a technology that lets you browse the internet as if you were on a private network, even while connected to a public one. This means greater security, anonymity, and online freedom.

A VPN doesn’t work as complicated as it sounds. Imagine your internet connection as sending letters through a postman. Without a VPN, anyone could read them. With a VPN, those letters stay inside a locked box. Only you and the recipient have the key. Therefore, your online activity stays encrypted and protected from prying eyes.

VPNs go beyond security. They let you simulate another country to access geo-restricted streaming content, block advertisers and trackers, and perform sensitive tasks safely. Do you work online? By using a reliable remote work VPN, you can access intranets or maintain stable cloud connections.

VPN technology appeared in the 1990s. Companies needed secure ways to connect employees to corporate networks remotely. At first, only large corporations used them. However, growing privacy concerns made VPNs popular among everyday users.

Today, VPNs are accessible to everyone. They have become essential for safe browsing in an increasingly digital world.

Types of VPN

Now that you know a VPN is highly recommended, you may wonder: Are all VPNs the same? Any will do? The answer is no. Not all VPNs work equally or serve the same purpose. Before choosing one quickly, it’s important to understand the available types and how they can improve your online experience. Let’s review the main options you’ll find:

1. Remote access VPN

This is the most popular VPN type for individual users and remote workers. Its main purpose connects a single device, such as your laptop or phone, to a private network through the internet. For example, you can access office resources from home or stay protected while browsing public Wi-Fi.

• How does it work? A VPN client encrypts data and creates a secure tunnel between the user and the private network.
• Who is it useful for? Remote workers, digital nomads, and anyone who wants secure browsing on public networks.

2. Site-to-site VPN

Also known as a router-to-router VPN, this type is designed to connect entire networks, rather than individual devices. Companies with offices in different locations commonly use it to share data securely.

• How does it work? It establishes a secure tunnel between networks. It allows all devices in both offices to communicate as one network.
• Who is it useful for? Businesses with multiple offices or corporations working with subsidiaries.

3. VPN for mobile devices

This VPN is specially designed for smartphones and tablets. It adapts to mobile behaviour. Since mobile devices frequently change networks, such as from your Holafly eSIM to Wi-Fi, these VPNs ensure stable and secure connections at all times.

• How does it work? It uses lightweight and fast protocols that consume less battery and data.
• Who is it useful for? Users who work or browse mainly from smartphones or tablets.

4. Cloud VPN

This VPN type is designed for companies that rely primarily on cloud services. Instead of connecting physical devices, cloud VPNs protect applications and data hosted on remote servers.

• How does it work? It creates a secure tunnel between the corporate network and cloud applications.
• Who is it useful for? Companies using Google Workspace, Microsoft Azure, Amazon Web Services, or other remote work tools.

5. P2P VPN

This VPN is very useful for users who download or share large files through peer-to-peer networks. This type of VPN optimises speed and privacy during data transfers.

• How does it work? It offers dedicated servers that allow fast and secure transfers, avoiding restrictions or blocks.
• Who is it useful for? Users of platforms like BitTorrent who seek anonymity and speed.

6. Business VPN

These VPNs are comprehensive solutions designed for companies that want to protect their entire corporate network. They offer advanced features, such as access controls, activity monitoring, and protection against cyber threats.

• How does it work? It configures virtual private networks tailored to business needs and integrates them with existing infrastructure.
• Who is it useful for? Businesses that prioritise security and efficient network management.

As you can see, many options exist on the market. The best VPN type depends on your specific needs. Do you want protection while travelling? Choose a remote access VPN. Do you manage multiple offices? A site-to-site VPN will suit you best.

VPN protocols

If you’ve already started researching VPNs, you’ve probably seen a technical term you may not fully understand: protocols. VPN protocols define how your device connects to VPN servers. In simple terms, they are the rules that determine security, speed, and connection stability. Not all protocols work the same. Some prioritise speed, while others focus on encryption strength or device compatibility. Let’s look at the most common ones:

OpenVPN

OpenVPN is one of the most widely used and reliable protocols available. It combines strong security with solid speed. Therefore, it works well for both individual users and businesses.

Why use a VPN when connecting to the internet?

As mentioned earlier, VPNs have become almost essential tools for internet browsing. But what makes them so important? The answer lies in everything they offer. From protecting your privacy to unlocking location-blocked content. VPNs provide a versatile solution for a digital world full of challenges. Let’s explore the main reasons why you should consider using a VPN daily.

1. Privacy while browsing the internet

Browsing without a VPN is like walking around with a sign showing your personal information. The websites you visit, your passwords, and even banking details may remain exposed to hackers or aggressive advertisers.

• How does a VPN protect your data? When you use a VPN, it encrypts your connection. This means all your online activity stays protected. This is especially useful when connecting to public Wi-Fi networks in cafés, colivings, airports, or libraries. Although convenient, these networks attract cybercriminals.
• Who is it useful for? Anyone who values privacy. Especially users making financial transactions with US banks or European institutions. It also helps people handling confidential information.

2. Access to geo-restricted services

Have you ever tried watching a series or film and seen the message: ‘This content isn’t available in your region’? This happens because many streaming platforms limit content based on location.

• How does a VPN help avoid these messages? A VPN lets you simulate being in another country. Want to access the US Netflix catalogue or watch a Japan-exclusive series? A VPN makes this possible. It also allows access to foreign company intranets and networks.
• Who benefits from unlocking international content? Frequent travellers, digital nomads, and global content lovers who don’t want to miss anything.

3. Security on public networks

Do you often use free Wi-Fi in cafés, hotels, or airports? Although convenient, it’s risky. These networks are vulnerable to attacks that intercept your connection. You need a reliable VPN.

• How does a VPN protect you on public Wi-Fi? By encrypting your data, a VPN creates a secure tunnel that protects your connection, even on unsafe networks.
• Who is it useful for? Remote workers, students, and anyone who connects from public places.

4. Avoiding censorship and restrictions

In some countries, certain websites or apps remain blocked. You may lose access to social media, communication platforms, or even basic services like Google.

• How does a VPN help here? It bypasses restrictions by connecting you to servers in countries where content is available. Using a VPN in China or other restricted countries ensures full access.
• Who is it useful for? Travellers visiting restrictive countries or users who want unrestricted internet access.

5. Saving money on online purchases

Did you know flight or hotel prices may depend on your location? Many platforms adjust prices based on where you connect from. This means you may pay more simply because your connection shows a wealthier country. Sounds unfair, doesn’t it? A VPN can become your best ally, you can:

• Optimise travel expenses: Connect your VPN to countries with lower fares for flights and accommodation. Booking platforms such as Skyscanner and Booking often adjust prices by location. You can secure cheaper hotels and cheaper flights using a VPN.
• Save on digital products: Some streaming subscriptions, software, or games have regional pricing. A VPN helps you access lower rates.
• Avoid price discrimination: Online shops often inflate prices based on browsing history or location. A VPN prevents this by enabling anonymous browsing.

6. Avoiding advertising tracking

Have you noticed how adverts seem to know exactly what you need? This happens because many companies track your activity to show personalised advertising.

• How does a VPN help? It hides your IP address and encrypts your activity. This makes tracking far more difficult.
• Who benefits from this? Anyone who wants to browse without being bombarded by personalised adverts.

7. Faster and more stable connections

You may have noticed. Your internet slows down while streaming, downloading large files, or gaming online. This isn’t random. Many internet service providers apply ‘throttling’. This technique intentionally limits your speed when detecting high-bandwidth activities. Although ISPs call it network management, users often find it frustrating.

How does a VPN help here? When you use a VPN, it encrypts all your internet traffic. This prevents your provider from seeing your activity. Since they can’t detect streaming or gaming, they can’t slow your connection. In short, a VPN hides your activity and helps maintain maximum available speed.

Which devices support a VPN?

By now, we understand many aspects of VPNs: What they are, available types, their benefits, and supported protocols. But where can you use them? You’ll be pleased to know you can install a VPN on almost any device you use to connect online. Are you working on your computer? Watching a series on a tablet? Browsing on your phone? It doesn’t matter. A VPN adapts to your needs, regardless of the device.

Moreover, this technology doesn’t only protect individual devices. You can also configure a VPN on routers to secure your entire home network or even on gaming consoles. Let’s see where and how you can install it.

Computers (Windows and macOS)

Computers are the devices we use most for work, browsing, and managing important documents. We spend hours online using them, which makes them prime targets for digital threats. Installing a VPN on your computer strengthens connection security and provides freedom from geographical restrictions or corporate network blocks.

A computer VPN offers benefits beyond privacy. It lets you work safely on public Wi-Fi, unlock restricted content, and ensure sensitive data, such as passwords or banking information, remains protected. It’s an investment in peace of mind, especially if you perform critical tasks.

How do you set up a VPN on laptops for digital nomads, remote workers, or leisure users?
