You might have already heard of virtual private networks that let you access and surf the world wide web in secure and anonymous manners. You may feel that you might not need to use one either and that’s fine, but many people share the sentiment that they want to know they can’t be tracked while they surf online resources. Many websites for instance use cookies which can be used to store information about any user browsing their website and some people have an issue with this as it can be considered a breach of their privacy. Cookies are used for various things after all.

For instance, the longer you spend browsing the catalogue of some online shop, the more they can give you recommendations on some products you might be interested in because they’ll be able to know what you’ve been doing while visiting their website. Likewise, the ads they display will also slowly become more accustomed to your tastes so that the chances that you click on one increase. Ad revenue is a big part of any website and popular social media sites like Facebook use cookies to better their user experience by keeping them up to date about the things they might be interested in.

Of course, this isn’t the kind of thing that everyone wants to indulge in. Some websites store private information like our credit card info so that the next time we decide to shop from there, checkout is fast and simple. Though convenient, there are security risks attached to it. VPN’s like also serve to prevent internet censorship in some parts of the world. You can even set up your own virtual network if you know, there are many guides available for such techniques online. All one needs to do is search.
