Mobile security is entering its most transformative phase yet. Mobile is now the largest attack surface in the enterprise, and the least protected. In 2026, two forces will converge to redefine risk: regulatory shifts and the acceleration of AI-driven development. These changes will not only reshape how mobile apps are built, distributed, and secured but also challenge enterprises to rethink their governance, strategy, and resilience. The winners will be those who adapt quickly, leveraging AI responsibly while embedding mobile security into the foundations of development, not bolting it on after the fact.
