A VPN encrypts your internet traffic and routes it through a third-party server, which is genuinely useful on public Wi-Fi or for basic location privacy — but a free VPN has to fund its servers somehow, and not every provider is honest about how. Some free VPNs log and sell browsing data, which defeats the entire purpose of using one in the first place.
Key takeaway: Proton VPN's free tier and Windscribe's free plan are both run by companies with a credible privacy record and clear limits; free VPNs from unfamiliar or ad-funded developers deserve real caution.
Proton VPN: unlimited data, no logging
Proton VPN, from the makers of the privacy-focused Proton Mail, offers a free tier with no data cap and a genuinely audited no-logs policy. The trade-off is a smaller selection of available server locations on the free tier and generally slower speeds than its paid plans, but for everyday browsing and public Wi-Fi protection, it's one of the most trustworthy free VPNs available.
Windscribe: generous data allowance
Windscribe's free tier includes 10GB of data per month (more if you confirm your email and tweet about it, per their own promotion), access to a reasonable spread of server locations, and a solid privacy policy. It's a good choice if you only need a VPN occasionally, such as when travelling or using public Wi-Fi, rather than for constant all-day use where the data cap would run out.
Before you start: A "free" VPN with no data cap, no subscription option, and no clear business model is very likely funding itself by logging and selling your browsing data. If you can't find a clear answer to "how does this company make money", that's a warning sign, not a neutral detail.
What a free VPN can and can't do
- Can: Encrypt your traffic on untrusted public Wi-Fi (cafes, airports, hotels), hiding it from others on the same network.
- Can: Mask your IP address from websites you visit, offering a basic layer of location privacy.
- Can't: Make you fully anonymous online — your VPN provider itself can still see your traffic unless it has a genuinely verified no-logs policy.
- Can't: Reliably unblock every streaming service's regional content — many services actively detect and block known VPN server IP addresses, including on free tiers.
Free VPNs to be cautious about
Be especially careful with free VPN apps found through a general app store search with no established parent company, unclear ownership, or reviews mentioning excessive ads or slow speeds that push users toward an upgrade. Several free VPN apps have previously been found selling user browsing data or including malware in their installers — a pattern documented by independent security researchers over the years. Stick to VPN providers with an established, named company behind them and a clearly published privacy policy you can actually read.
Tip: Check whether a VPN provider has published an independent, third-party audit of its no-logs claims — Proton VPN and a small number of others have done this, which is meaningfully more trustworthy than a company simply stating "we don't log" on its own website.
A free browser-based alternative
Microsoft Edge includes a free built-in VPN feature (Edge Secure Network) with a modest monthly data allowance, encrypting traffic only within the browser itself rather than your whole device — a reasonable lightweight option if you just want basic protection while browsing, without installing separate VPN software.
| Provider | Data limit | No-logs policy |

| Windscribe (free) | 10GB/month | Published |
Frequently asked questions
- Do I need a VPN for everyday home internet use?
- Not strictly — your home Wi-Fi with WPA2/WPA3 encryption is already reasonably secure. VPNs matter most on public or untrusted networks.
- Can a free VPN slow down my internet noticeably?
- Yes, free tiers typically have fewer, more crowded servers than paid plans, so some speed reduction is normal and expected.
- Is it illegal to use a VPN in the UK?
- No, using a VPN is legal in the UK. It simply must not be used to facilitate illegal activity, the same as any other legitimate tool.
