The growing increase in cyberattacks overwhelms the ability of organizations to reliably contain and maintain their operations. In this sense, current good practices and standards create a false sense of security that is usually exploited by attackers to create areas of instability that end up compromising not only their operations but also their promise of value. Therefore, the FLEXI model and its basic practices are proposed as an unconventional alternative that prepares the organization to assume the uncertainty and instability as the new normal of its operation, which is to learn, cushion and rebound in the face of a successful cyber event, where the challenge is to overcome the vision of silos in the organization to build a collective defense that generates greater uncertainty to the adversary's risk model and a better organizational posture in the face of the inevitability of failure.
