Mullvad is intended to protect your privacy when you surf the Internet. Similarly, it lets you bypass geo-restrictions and ISP rules. I am sure you will not have any problems to use this application. It has a simple-to-use interface, that looks similar to most other VPN clients. It lets you choose a location and then activate the VPN to create a secure connection. Regrettably, unlike some similar tools, Mullvad does not provide any statistics about the current speed and usage of the available servers.
It seems that number one priority for Mullvad is anonymity. In this respect, it is great that you do not need to provide any personal information to use it. In fact, this has been taken to the extremes: instead of a username or password, you are assigned a random numeric code. Of course, there is the risk of someone else just guessing your number, but this is quite improbable statistically speaking. Moreover, the service keeps no permanent logs of your activity. On top of that, your payments can be done by sending cash or cryptocurrencies. There is always a risk that your data transfers may get intersected by third parties. Luckily, Multivad uses highly powerful algorithms for data encryption (AES-256-GCM) and data authentication (SHA384).
Mullvad operates a wide network of servers in multiple countries, which is essential in pretending you are located somewhere else. In addition, there is the advantage that all of them are physical servers, unlike other VPN services that use a combination of physical and virtual servers. Connection speeds may vary depending on the location you have selected, but they are normally good. However, it lacks some of the features you can find in other similar services, such as double VPN and Onion over VPN.
To conclude, Mullvad stands out among so many VPN services out there because of the almost total anonymity it guarantees. Data travels strongly encrypted and connection speeds are quite good. The service requires a monthly payment.
