VPN security varies
A clear example is the encryption type that has the VPN. This is what will really protect the connection and will prevent the information we send or receive from leaking into the network. it can have symmetric encryption, public key encryption, or hashing, which uses the SHA algorithm. If we analyze the symmetric encryption, for example it can be AES-128, AES-196 or AES-256 bit, the latter being the most robust.
When you are going to install a VPN you should carefully observe what type of encryption it uses. The size of the encryption keys, which is what we see with AES-128 or AES-256, for example, is important. The older it is, the more a hypothetical intruder would need to gain access to the information we are exchanging.
Another point to note is whether the VPN save record or logs. What does this mean? Basically whether or not it stores a record of the sites you visit. Many VPNs, especially the free ones, can sell that information to third parties and profit from it. This logically puts the privacy of users at risk.
If you want maximum privacy and avoid problems, it is a good idea to check if the VPN you are going to install stores a log or not. Ideally, it should not store any user information.
An interesting feature is that it has kill switch. It is a feature that automatically disables the VPN if it detects any problems. In the event that it stops working, we do not continue browsing the network without protection, but rather it will automatically disconnect us and thus protect the data.
Tips for choosing the VPN
As you can see, not all VPNs are going to act the same in terms of security. For this reason, it is essential to choose very well which one to install. What should we consider? An important tip is avoid the ones that are free. That is where we can have more problems. Always install paid applications or, at least, that are guaranteed.
You can inform yourself well on the Internet, look for comments and ratings from other users, go to legitimate application stores such as Google Play and, in short, take references before installing anything. In this way you will be able to avoid problems and you will surf the net with total protection, without your privacy being compromised.
Also, it is a good idea that the VPN you use has many servers. This way you will make it work better, no matter where you are. It is interesting to have many options to connect to other countries and thus achieve good performance. This also implies greater protection, since not all countries have the same regulations and it should be taken into account.
In short, as you can see, it is important to choose well which VPN to use. They don’t all work the same and spending some time choosing which one to install can help you avoid problems. Always install software that is guaranteed. This will also prevent problems if the browser goes bad over VPN.
