Nitrokey, based in Teltow, Germany, develops IT security hardware. Its range includes hardware security keys for passwordless login, two-factor authentication, computer login and SSH administration, as well as the NetHSM hardware security module, the NitroPhone and the NitroPC. The company describes its offering as open-source IT security hardware. The firmware of the Nitrokey 3 keys is published on GitHub under the Apache 2.0 and MIT licences, while the licence terms of the hardware designs are not covered by these pages.
Nitrokey GmbH is registered in Germany, with its address in Teltow and its commercial register at the Amtsgericht Potsdam. The company site mentions NetHSM-as-a-Service, but the pages reviewed do not say where that service runs, so European organisations should request the processing location in writing. Because the firmware is published, an organisation can inspect the published code. Licences differ between products, so each product should be checked before deployment.
