Zero Trust is a security framework requiring all users, whether inside or outside the organization's network, to be authenticated, authorized, and continuously validated before being granted or keeping access to applications and data, in order to ensure proper security configuration and posture. Today industries rely on Internet-of-Things (IoT) devices to automate processes, improve service delivery, bring user convenience and innovation in people's lives. As a result, IoT Security has become an increasingly crucial subject nowadays. Security in this field inherently becomes something requiring management through innovative and technical approaches to protect enterprise infrastructure and business applications. At Deloitte Switzerland both topics have been studied and put in practice in order to help clients enhance their business activities and improve their security infrastructures.
