Microsoft emphasises that cybersecurity is a shared responsibility; that while Microsoft handles the infrastructure, cloud platform and many foundational protections, it is up to organisations (and their employees) to secure their data, access, identity and adoption practices. In other words: good infrastructure is necessary, but not sufficient.
Moreover, Microsoft has openly shifted to treating security as everyone’s job. For example, security efforts are now formally woven into performance goals and evaluation metrics for many employees, which underscores how seriously even big tech firms now view the human factor.
