ProtonMail is based in Switzerland, a country known for its strong data protection laws and neutrality.
This location is significant because it means ProtonMail is not subject to US or EU data retention laws, providing an added layer of security for users.
Switzerland's data protection laws are particularly strict, requiring companies to obtain explicit consent from users before collecting and storing their data.
This emphasis on user consent and data protection is a major selling point for ProtonMail, which prides itself on being a secure and private email service.
ProtonMail's Location and History
ProtonMail was born in Switzerland, specifically at the European Organization for Nuclear Research (CERN) in Geneva, where many of the early team members worked together on particle physics experiments.
Switzerland is also where Sir Tim Berners-Lee invented the World Wide Web in 1991, which led to the internet as we know it.
Data Centers and Security
Proton Mail maintains and owns its own server hardware and network, avoiding third-party usage.
The company operates two data centers, one in Lausanne and another in Attinghausen, which is a former K7 military bunker under 1,000 meters of granite rock.
Each data center uses load balancing across web, mail, and SQL servers, redundant power supply, and hard drives with full disk encryption.
Proton Mail exclusively uses Linux and other open-source software.
As of December 2024, Proton operates data centers in Switzerland, Germany, and Norway.
ProtonMail's servers are located in Switzerland, outside of US and EU jurisdiction, providing an added layer of security.
The company's servers are hosted in a former military command center deep inside the Swiss Alps, offering maximum physical security for clients' data.
Switzerland's unique set of privacy laws, as set out in the Swiss Federal Act on the Surveillance of Postal and Telecommunications Traffic (SPTT), last revised in 2012, exempt ProtonMail from providing technical means for lawful interception.
