VPN ads often promise complete anonymity and protection against all dangers. The reality is simpler: a VPN is a useful tool, but it solves a specific problem. In this article, we explain how a VPN works, when it really helps, when you can do without it and what to look for when choosing a service.
What is a VPN and how does it work
A VPN, or virtual private network, creates an encrypted connection between your device and the VPN service's server. All internet traffic travels through this encrypted tunnel, so the local network administrator or other users of the same Wi-Fi network cannot see which websites you visit or what data you send. The websites you connect to see the VPN server's address instead of your real IP address.
In practice it is simple: you install the app, sign in to your account and turn on the secure connection with one button. Then you browse, watch videos or use online banking as usual.
What a VPN protects against
- Data interception on public Wi-Fi networks in cafés, airports and hotels
- Others on the local network seeing your browsing history
- Websites seeing your real IP address and approximate location
- Some tracking, if the VPN service has ad and tracker blocking
What a VPN does not protect against
It is also important to know the limits of a VPN so as not to get a false sense of security:
- A VPN is not an antivirus – it does not detect or remove malware.
- A regular VPN does not protect you from phishing if you enter your details on a fake website yourself. Some services have additional protection against dangerous websites, but it is no substitute for caution.
- A VPN does not make you completely anonymous – once you sign in to your accounts, websites still recognize you.
- It does not make weak or reused passwords safe.
That is why a VPN works best together with an antivirus and a password manager.
When a VPN is really worth buying
You often use public Wi-Fi
If you work in cafés, travel or connect to hotel networks, a VPN is one of the most practical forms of protection. On a public network you do not know who controls it or who else is connected, and an encrypted connection reduces the risk of your data reaching third parties.
You work remotely
For people working remotely, it is important that work email, documents and logins are transmitted securely, even when connecting from outside the office. If your company has its own VPN for access to internal systems, use it – a personal VPN does not replace it, but it protects the rest of your browsing.
You travel
When traveling, a VPN lets you connect through a server in another country and use online banking more safely on a hotel or airport network. But keep in mind that some services restrict VPN access in their terms, and laws differ from country to country.
You want more privacy at home
Even at home, your internet provider can see which websites you connect to. If privacy matters to you, a VPN hides this information from the provider and other network users.
You want to protect your whole family's connection
Many VPN services let you use one account on several devices at the same time. This is convenient for families: parents’ computers and children’s phones and tablets can use the same license, and children connecting to school or café Wi-Fi will be protected too.
When you can do without a VPN
If you only use the internet at home on a secure Wi-Fi network with a strong password, and the websites you visit use an encrypted HTTPS connection, a separate VPN is not necessary. In that case, a good antivirus and up-to-date software matter more.
In addition, a VPN is already included in some antivirus suites, for example Kaspersky Plus, Kaspersky Premium or F-Secure Total, so you may not need to buy one separately. Before buying a VPN, check whether your current license already includes it.
How to choose a VPN
- Number of devices – how many computers and phones can use the service at the same time.
- Operating systems – whether there are apps for Windows, macOS, Android and iOS.
- Kill switch – a feature that cuts the internet connection if the VPN connection drops unexpectedly.
- Server countries – whether there are servers in the countries you need.
- Additional protection – blocking ads, trackers or dangerous websites.
- Validity period – whether the license is for one year or several years.

- Create a service account or sign in to an existing one and enter the key you received.
- Download the app from the manufacturer's website or an app store.
- Sign in to the app with the same account and turn on the VPN connection.
- In the settings, turn on automatic connection on untrusted Wi-Fi networks if the app offers it.
Frequently asked questions
Does a VPN slow down the internet?
Encryption and connecting through a remote server slightly affect speed. If you choose the nearest server, the difference for everyday browsing and videos is usually small.
Is a VPN legal in the EU?
Yes, using a VPN is legal in Lithuania and other EU countries. However, a VPN does not remove liability for illegal activity online.
Is a free VPN good enough?
Free VPNs often have data, speed or server limits. Besides, the provider has to earn money somehow, so it is worth reading its privacy policy carefully.
Should the VPN be kept on all the time?
Not necessarily. A VPN is usually turned on when connecting to public or untrusted networks. At home, you can use it when you want more privacy. Some banks or local services may ask for additional verification over a VPN – in that case, turn the VPN off temporarily or choose a server in your own country.
What is the difference between a VPN in an antivirus suite and a standalone VPN service?
In an antivirus suite, the VPN is one of the features, managed in the same app and account. A standalone VPN service usually offers more settings, a choice of servers and additional features. If you already have an antivirus and its VPN is enough for you, there is no need to buy one separately. If you use a VPN a lot and every day, a standalone service is worth choosing.
Can I use a VPN on my phone?
Yes. Most VPN services have apps for Android and iOS phones, and one license usually covers several devices.
Conclusion
A VPN is worth buying if you often connect to public Wi-Fi networks, travel, work remotely or simply value your privacy. However, it does not replace an antivirus. If you need both, consider an antivirus suite that already includes a VPN. Before buying, count your devices and check whether the service has apps for all the operating systems you use.
