The Swiss military has banned the use of messaging apps such as Whatsapp, Signal and Telegram while on duty. The army prefers a Swiss service, a spokesman confirmed.
In late December, the Swiss military issued a notice requesting soldiers to use the Swiss messaging service Threema and not to use other applications for communication on their private phones during operations.
Threema is already used within the government in Switzerland. In addition, the application would be more secure in terms of data protection than other services. For example, it does not fall under the Cloud Act, a US law from 2018 that allows US judges to demand access to data, even if that data is on servers outside the US.
Threema promises secure communication without requiring users to provide a phone number or email address. Ten million people would already use it, says the company itself. Unlike Whatsapp, the application is not free but costs EUR 3.99 once to download. The military will bear that cost.
