Probably, you have already learnt that VPN was introduced more than fifteen years ago and its primary aims have changed a lot so far. Today many Mac and other system users run the service for their online freedom and protection. A VPN offers a wide range of services from shifting your true virtual address to anonymizing your network. Nevertheless, one of its most important functions is to make your traffic encrypted and locked from prying eyes.
How does encryption work? So, a good VPN creates a secure tunneling between your connected device and one of its servers. While receiving or sending some traffic via the tunneling there are different protocols and keys used by the provider to make your data unreadable and inaccessible. There is a pretty wide range of protocols for today, but just a few years ago there was PPTP protocol, which was the most usable protocol for safe data transferring via the internet. The protocol was developed by Microsoft and due to the fact that it is so easy to set up it has become one of the most spread methods of encryption.
However, it seems to be pretty out-of-dated, as it doesn’t provide a leak-proof defense anymore. It has been also revealed that PPTP encrypted data can be decrypted by unauthorized user within a day. This fact has made many companies to overview the policy of confidentiality and online protection, as many companies continue using the protocol for faster operation. So, running the protocol poses under a risk all your data transferred on the internet or saved on a cloud. Good news is that the out-of-dated protocol has up-to-date equivalents such as OpenVPN or L2TP, which are to provide your network with higher rate of defense. So, having decided to subscribe for the best VPN for Mac, you need to make sure it supports multiple protocols and keys for your network protection.
