Ever since the scandal involving the US NSA in 2013, it has become more and more clear that government agencies like that one are constantly monitoring all the online activity they can. Countries like the UK, Australia and Canada have also recently passed bills that allow them to legally monitor internet activity collected by ISPs. And this is just the tip of the iceberg.

On top of all this, it is also known that a lot of companies are constantly tracking people’s online habits and generating statistics based on their preferences to profile them and sell this information to advertisers. They do this with the goal of tailoring ads to internet users, but in the process, they violate most people’s privacy. They get away with this thanks to the small print in terms of usage contracts and other things like that, but these service conditions are unfair and you should have a means to do something about it. This is where VPNs come in.

How VPNs Work

In essence, VPNs are networks of servers that work as a bridge or tunnel for your internet connections. When you browse the internet using a VPN, all your internet traffic is rerouted through one of these servers and in the process, it all gets encrypted to hide it away from prying eyes. VPNs for those who aren’t experts in computer science are usually very easy to use services that are based on a subscription scheme. If you don’t know where to start, we recommend you to take a look at ExpressVPN, IPVanish or PureVPN, which are considered as Top VPNs for 2017 by vpnAlert.

How They Protect You

Here are some of the reasons why VPNs are considered the best tool to protect your privacy online.

VPNs Mask Your Traffic: Using a VPN, all your connections have to go through a VPN server before they arrive at their destination. Thanks to this your ISP can’t know the real website you’re accessing and the websites can’t track your requests back to you, there will always be a server in the middle to confuse things.

Sniffers Can’t Use What They Get: All your traffic is encrypted, so it doesn’t matter if anyone catches some of it by exploiting a vulnerability over your network, this data will be useless without the decryption keys owned only by your device and the VPN server.

Tracking Protection: Every website that attempts to track your browsing habits won’t be able to build reliable information because it won’t be able to reach your actual data. Some VPN services even have software that blocks tracking altogether so you’ll be protected one way or another.

And these are just the more evident and less technical features we can mention about them. Good VPN providers add extra layers of protection to all this using complex encryption algorithms and implementing software solutions to prevent your connections from leaking personal info. If you’re concerned about your privacy online, then VPNs are just the way to go.
