VPN stands for Virtual Private Network and does pretty much what it says. Most people use VPNs for accessing websites that would otherwise be blocked, such as US Netflix if you're outside of the US. But a VPN also adds a layer of security by making you totally anonymous online.

You'll find more in-depth information in our best VPN roundup, but here we share browser VPNs that you can download now.

These days, you can download a free web browser with built-in VPN capabilities, but if you want to continue using Chrome or Firefox (both of which currently lack a built-in VPN), you can install extensions or plug-ins to do the same job.

Another alternative is a standalone application which automatically routes all web traffic through a VPN. Many of the best VPNs aren't free, but there are lots of free options.

NordVPN

NordVPN

Our pick of the best VPN available in 2017 has just released a Chrome browser extension, adding to its portfolio of VPN products for iOS, Android, macOS and Windows.

If you already have an account with NordVPN you'll be able to use this browser extension at no extra cost. If you've yet to sign up, you can choose between four plans: 1 month for $11.95, 6 months for $42 ($7 per month) or a year for $69 ($5.75 per month) or the cheapest, which is two years for $79 ($3.29 per month). Sign up here.

Once you've signed up, you can download the extension here and begin using it to protect web traffic through Chrome using a simple, easy to use tool.

Opera

Opera

Of all the popular mainstream web browsers, Opera is the first to offer a built-in VPN service. To try out the new browser for free, with an unlimited VPN, you can visit Opera's website here.

It protects your identity by hiding your activity within the folds of a virtual network. The service operates a no-log policy, which means that no records are kept of the sites you visit, passwords you enter, or any downloads you make.

You can select from three regions to start with including Canada, USA, Germany: this becomes your virtual location. As well as giving your browser the added panache of being well travelled, this also opens up region-locked content from various streaming services.

Tor

Tor

When it comes to online anonymity one name looms larger than all others. Tor has long been the refuge of those who want to avoid the glaring eye of government surveillance, or potentially sensitive data being hacked by nefarious parties.

Journalists use it to converse with sources, as do a number of other professions and general users.

The Tor browser is free and works very much like Firefox, as it appears to share the same engine.

Once installed you simply use it as you would Chrome or IE, but Tor recommends that you don’t install any plug-ins such as Flash and the like, as they can be a security risk.

Tor is already a byword for security online, and using it makes sense for those who value their privacy.

CyberGhost

CyberGhost

CyberGhost has built a solid reputation for security and transparency over the years. The platform boasts a number of key features that make it one of the safest ways to roam the internet.

Alongside the anonymising of your online identity, CyberGhost also features military grade encryption to fend off hackers who would try to steal your data on public WiFi hotspots.

You don’t need an additional browser or plug-in, as CyberGhost works with pretty much everything and is even available as an app for Android and iOS.

An ad-blocker also makes surfing even quicker, although it does deprive impoverished writers of their hard earned money.

It's available for $2.90 per month if you commit to two years, $4.99 per month for one year, $7.99 per month if you opt for six months and $10.99 if you want just a month.

Hide.Me

Hide.Me

Available from Hide.me

Another solid choice of VPN browser is Hide.me, which offers a free tier as well as paid premium accounts.

The free version is a browser that’s limited to 2GB of data per month (so no HD movies on this one), no port forwarding, and a choice of three worldwide locations for your VPN server (Canada, Netherlands, and Singapore).

As a free tier this is actually one of the best we’ve seen, and perfect if you want to give the service a thorough test before you move up to a premium plan.

Hide.me boasts AES 256 encryption, a no-log policy, as well as claiming to be the fastest VPN online. Thankfully you can test this out for yourself before you need part with money. If you’re happy then you could opt for the completely unlimited plan which costs around £8 per month.

Hide.Me is cross platform, with apps available for Windows, MacOS, Android, iOS, and Linux.
