Using a VPN Online: What You Need to Know
A virtual private network (VPN) can help protect your internet connection by sending your online traffic through an encrypted connection to a VPN server. VPNs are used by individuals, remote workers and businesses, but they are not a complete solution to online security. Understanding what a VPN does—and what it does not do—can help you decide whether one is right for you.
What does a VPN do?
When you connect to the internet without a VPN, your internet service provider can generally see information about the services and websites you connect to. Websites may also see your connection’s IP address, which can reveal your approximate location.
A VPN routes your connection through a server operated by the VPN provider. The connection between your device and that server is encrypted, helping to protect your traffic from being read by others on the same network. Websites usually see the VPN server’s IP address rather than your original one.
Why use a VPN online?
- Extra protection on public Wi-Fi: Encryption can make it harder for others on an unsecured or shared network to inspect your connection.
- More privacy from your local network: A VPN can limit what your internet provider or the operator of a public Wi-Fi network can see about your browsing connections. The VPN provider may, in turn, be able to see some connection information.
- Remote access: Employers may provide VPNs so staff can securely connect to workplace systems from outside the office.
- IP address masking: A VPN can hide your usual IP address from websites and services, although it does not make you completely anonymous.
What a VPN cannot do
A VPN does not prevent every online threat. It will not necessarily stop phishing, malicious downloads, scams or tracking through cookies and browser fingerprinting. If you sign in to an account, that service can still identify you through your account activity.
A VPN also shifts some trust from your internet provider or network operator to the VPN provider. The provider may be able to observe aspects of your connection, so its privacy policy, security practices and business model matter. Be cautious of services that promise total anonymity or guaranteed protection.
How to choose a VPN
Before subscribing, consider what you want the VPN for. Look for clear information about the provider’s privacy policy, the data it collects, how long it keeps that data and whether its claims have been independently assessed. Other useful considerations include:
- Strong, modern encryption and secure connection protocols.
- Clear pricing, renewal terms and cancellation arrangements.
- Apps that receive regular security updates.
- Reliable customer support and compatibility with your devices.
- Transparent ownership and contact details.
Free VPNs can be tempting, but some may have limits, display adverts or collect data to support their service. Read the terms carefully and avoid installing apps from unfamiliar sources.
Using a VPN safely
- Download the app from the provider’s official website or your device’s trusted app store.
- Use a strong, unique password and enable multi-factor authentication if available.
- Keep the VPN app, operating system and browser up to date.
- Check that the VPN is connected before carrying out tasks where you want its protection.
- Continue using other security measures, such as strong passwords, multi-factor authentication and caution with links and attachments.
Are VPNs legal in the UK?
VPNs are generally legal to use in the UK. However, using one does not make unlawful activity legal, and a VPN does not exempt you from the terms of websites or online services. Rules and access restrictions can vary between services and countries, so check the relevant terms and local laws.
Is a VPN right for you?
A VPN can be a useful privacy and security tool, particularly when using shared networks or accessing workplace resources. It works best as one part of a broader approach to online safety—not as a replacement for secure devices, careful browsing and trustworthy passwords. Choose a provider carefully and understand what its service can and cannot protect.

Yes, some providers offer free VPN services, either as a limited plan or a browser extension. Check the provider’s privacy policy, data limits, security features and business model before using one, as free services may include restrictions or collect data.

Open the app, sign in, select a server location if needed, and tap or click “Connect”. Once connected, browse the internet as usual; the VPN encrypts the connection between your device and its server. Keep the app updated, check that the connection is active when you need it, and remember that a VPN does not replace other security measures or make you completely anonymous online.
Is using a VPN legal in the UK?
