Does a VPN make me completely anonymous online?

No. A VPN hides your IP address and encrypts your traffic, but it doesn't make you fully anonymous. Your browser fingerprint (a combination of your browser type, screen size, installed fonts, and other settings that can be used to identify you), cookies, and accounts you're signed into can all still give you away. True anonymity online requires a lot more than a VPN.

Can my internet provider see that I'm using a VPN?

Yes. Your internet provider can see that you're connected to a VPN server, though not what you're doing through it. That's not a concern in the UK, where VPN use is entirely legal.

Are browser VPN extensions safe?

Extensions from reputable providers (NordVPN, ExpressVPN) are reasonably safe, but they only protect traffic within the browser, not your whole device. Free extensions in the Chrome Web Store should be treated with the same scepticism as free VPN apps: if there's no clear way the provider is making money, your data is probably how.

How do I know if a VPN's no-logs claim is genuine?

Look for independent audits the provider has published. A credible audit names the firm that conducted it, describes what was checked, and makes the report available to read. If a provider claims a no-logs policy but has never been independently audited, the claim is unverified. Both NordVPN and ExpressVPN have published multiple rounds of audit results from named security firms.

Should I leave my VPN on all the time?

Generally, yes, if privacy is your main reason for using one. Keeping the VPN connected means your traffic is always encrypted and your real IP address is always protected. The trade-off is a small reduction in speed, because your traffic is being routed through an extra server. Most reputable paid VPNs are fast enough that you won't notice the difference for everyday browsing, streaming, or video calls.

The encryption itself is extremely difficult to break with current technology. What can go wrong is the VPN provider's own security: their servers, their systems, their staff. That's why choosing a provider with published audits and a clean track record matters. The real risk isn't someone cracking the encryption; it's trusting a provider that has poor security habits or quietly stores data it shouldn't.

Does a VPN slow down my internet?

A little, yes. Your traffic is encrypted and sent through an extra server before it reaches its destination, which takes slightly longer than a direct connection. With a reputable paid VPN on a nearby server, the difference is usually small enough that you won't notice it during normal browsing, streaming, or video calls. Free VPNs tend to be much slower because they run fewer servers shared among more people, and there's no business reason for them to fix it.

Are VPNs Safe? What You Need to Know

If you've just started using a VPN, or you're thinking about getting one, it's completely reasonable to wonder whether they're actually safe. The honest answer: it depends on which one you use. A good VPN from a reputable provider is genuinely safe. A bad one can do real harm, selling your browsing data to advertisers, bundling malware, or keeping records of everything you do online while claiming it keeps none.

The short answer

A paid VPN from a trustworthy provider is safe. It encrypts your internet traffic and hides your IP address from the websites you visit and from your internet provider. The risk isn't the technology itself; it's the company behind it. A bad VPN provider can see everything you do online, and some make money by logging and selling that data. The gap between a safe VPN and an unsafe one comes down to who is running it and how accountable they are.

What a VPN actually does to your traffic

When you connect to a VPN, all your internet traffic goes through the VPN provider's servers. Your internet provider can see that you're connected to a VPN, but not what you're doing. The websites you visit see the VPN's IP address rather than yours.

Here's the part worth understanding: the VPN provider can see your traffic. You're not hiding your activity from everyone; you're shifting your trust from your internet provider to your VPN provider. A good provider logs nothing and has no interest in your data. A bad one might log everything and sell it.

What to look for in a safe VPN

A genuine no-logs policy. This means the provider doesn't record your browsing activity, connection times, or IP addresses. The policy alone is just a statement on paper; what matters is whether it's been independently verified.

Independent audits. Reputable VPNs pay third-party security firms to check their systems and confirm their no-logs claims hold up in practice. NordVPN, ExpressVPN, and PureVPN have all published audit results from named firms. An unaudited policy is a marketing claim; an audited one is actual evidence.

Where the company is based. A VPN registered in a country outside major intelligence-sharing networks is a lower-risk choice. The Five Eyes, Nine Eyes, and Fourteen Eyes are groups of countries that share surveillance data with each other; a VPN based inside those networks can be pressured to hand over user information. NordVPN is registered in Panama; ExpressVPN in the British Virgin Islands. Neither is part of those groups, and neither country requires VPN providers to keep logs of user activity.

A real-world track record. Has the provider been tested under real pressure? In 2018, a server used by NordVPN at a Finnish data centre was accessed without authorisation by an unknown third party, who exploited a remote management tool the data centre had installed. When the incident was investigated, no user data was found because none had been logged. That real-world test is far more reassuring than any marketing claim.

Whether a VPN is safe is actually the wrong question to ask. The better one is whether the company running it can be trusted. The technology itself is well understood and has been scrutinised by independent researchers for years. What varies enormously is the provider. A VPN with published audits, a verified no-logs policy, and a history of protecting user data is a very different thing from one that charges nothing and has never been independently checked.

Why free VPNs are the main safety concern

Running a VPN service costs real money: servers, bandwidth, security staff, engineers. A VPN that charges nothing has to cover those costs somehow. The most common model is data collection: logging your browsing activity and selling it to advertisers or data brokers. That's the opposite of what a VPN is supposed to do. For the full picture on what free VPNs actually get up to, read Are Free VPNs Safe?

Several free VPN apps have been caught injecting ads into web traffic, selling user data to third parties, and routing strangers' traffic through their users' home connections without proper disclosure. A paid VPN has a clear business model: you pay for the service. A free VPN often has a business model you're not told about, and that's the problem.

There are a handful of legitimate free VPN options with strict usage caps (ProtonVPN's free tier is one), but for everyday use, a paid VPN from a reputable provider is the only reliably safe choice.

How to check your VPN is actually working

The easiest way is to check where your device appears to be located while you're connected. If the VPN is working, it should show the location of the VPN server, not your home.

Our free IP address checker does exactly that. Connect your VPN, open that page, and see where it thinks you are. If it shows your actual home location, the VPN isn't routing your traffic through its servers correctly. Try switching to a different server and check again.

Is using a VPN legal?

In the UK and the vast majority of countries, yes. VPNs are legal tools used by businesses, remote workers, journalists, and everyday people. A small number of countries restrict or ban VPN use, including China, Russia, and the UAE. If you're travelling to any of those places, it's worth checking the local rules before you go. Our guide on getting a VPN working in India covers what to expect when local restrictions affect your connection.

Using a VPN is legal; illegal activity remains illegal even with one. A VPN also doesn't protect you from everything: if you're signed into a Google or Facebook account, those services can still track you regardless of the VPN.

Common safety concerns, answered

VPN software security. Like any software, VPNs can have vulnerabilities. Reputable providers respond quickly to disclosed issues and push updates. The encryption used by modern VPNs is considered extremely strong. Protocols like WireGuard use encryption that would take longer than the age of the universe to crack by guessing; it's simply not a realistic attack.

VPNs and malware protection. A VPN encrypts your connection but doesn't scan for malware or block malicious websites, unless the provider includes an add-on threat protection feature. NordVPN's Threat Protection is one example. You still need separate antivirus software for full protection.

Employer visibility when using a VPN. It depends on the situation. If you're using your employer's VPN on a work device, they can potentially see your traffic. If you're using your own personal VPN on your own device, your employer can't see what you're doing, though if you're connected to their network they can see that you're using a VPN.
