There is no trust without cybersecurity; cybersecurity sometimes relies on the absence of trust granted a priori. In an increasingly hyperconnected, distributed, transactional world that demands collective and collaborative cybersecurity, Zero Trust emerges today as a response to the multiplied cybersecurity challenges. By making trust explicit, Zero Trust contributes to the cyber resilience of an increasingly complex and intertwined system. Identity management technologies, access control, detection, reaction, orchestration, micro-segmentation, invisibility, etc., promise a multi-layered and granular security, centered on the network endpoints. In the era of public cloud, telecommuting, extended organizations, the endless expansion of our attack surface, and their corollary, the proliferation of cyber threats, digital fortresses and the implicit trust that once prevailed are now obsolete.

Of course, this transformation is not a smooth sailing journey, with some criticizing it for the illusion of security it may provide, the induced technical complexity, the difficulty of user experience, limited societal acceptance, etc. But whether we like it or not, Zero Trust, even distrust, has indeed become the necessary prerequisite to (re)establish trust for all.
