The European messaging service Zivver, used by governments and hospitals in the EU and UK for confidential communication, has been sold to Kiteworks, a US company with ties to Israeli intelligence. This raises concerns about the security of sensitive information, as Kiteworks' management includes former members of an elite Israeli cyber unit. Experts worry that the data, now subject to US law, could be accessed by intelligence services. The acquisition has sparked debate about the protection of European citizens' data.
