The Norwegian Labor and Welfare Administration (NAV) manages one third of Norway's annual state budget through its various welfare schemes. When NAV moved out of their on-premises data centers and onto public cloud in 2020 it was clear that we needed a new approach to security - an approach where we did not assume trust just because you had network access. This was not an easy task. Today, NAV has 150 cross-functional product teams and over 1600 individual applications running in production on our Kubernetes.
