ProtonVPNs client software has built-in killswitch og always-on VPNwhich both increase safety. Killswitch, always-on VPN and DNS leak protection

The intention is that the user's identity will thereby be protected even if the server is to be compromised. Some of the servers use so-called Secure Core, which is a term for the connection to the server going through one of ProtonVPNs secured data centers in Switzerland, Sweden or Iceland, as all three are countries where the law protects privacy. If you need servers in special locations, you should just check if they are available ProtonVPNs network. There are servers in Denmark and on all continents, so most regular users will be well covered. ProtonVPN has a relatively small network with approx. In fact, you do not have to disclose your identity at all when you register as a user and payments are made using third-party payment services, so ProtonVPN does not even contain information that can be used to track a user. The only thing logged is the time of the last time a user connects to one VPNserver, but nothing about what the connection has been used for. No sensitive information is logged about the users' use of ProtonVPN, including visits to websites, downloads, application with programs, etc. They are therefore not required to record and store user data and their use of VPNservice, which they also do not. ProtonVPN is headquartered in Switzerland, where legislation largely protects privacy. The physical security of ProtonVPN is also impeccable, as the data centers are located must have protected locations such as former protection rooms and former military facilities.

In this way, data from other connections cannot be decoded if an encryption key is to be compromised for any reason. It is used perfect forward secrecywhich means that a new unique encryption key is created each time a connection is created. ProtonVPNs security is absolutely impeccable, as only open source encryption protocols are used.

It gives the huge advantage that it is impossible to sneak backdoors or the like into the encryption protocol, which could otherwise seriously compromise security. Connections are encrypted with 256 bits keys and handshakes (connection creation) with 2048 bits, both of which are the highest standard in encryption.ĭepending on the device used, the connection is encrypted with either the OpenVPN or IKE2v / IPSec, both of which are open source software, which means that the program code is publicly available. The safety of one VPNconnection to ProtonVPN can't get better, because only strong encryption keys and credible encryption protocols are used.
