Nowadays it is difficult to maintain privacy especially on the internet where there are numerous huge, powerful companies trying their best to get hold of your data for advertising and other purposes. Luckily, there are still Virtual Private Networks (VPNs) which would allow you to browse the internet anonymously.
Though that is the case, however, there is one case wherein one of the most popular VPNs has fallen prey to hackers. This not only complicates the issue but it also makes you lose confidence. Do not be disappointed as there is a solution for everything and one way to solve this issue is through the use of an open source VPN.
