In today's world, network security is of utmost importance for companies and authorities as data and information are increasingly being stored and transmitted through cloud solutions. This has led to a higher risk of cyberattacks. To enhance security during this transition, Zero Trust has emerged as a promising concept, with its direction from an internal IT-environment to a more secure cloud solution. Its main motto "never trust, always verify" emphasizes the importance of a high level of security. This study aims to highlight the significance of Zero Trust and compare the attitudes of Swedish companies and authorities towards its implementation.

The study was conducted using semi-structured interviews with IT experts who possess knowledge in this domain. Additionally, a literature review was conducted to connect the outcomes of the interviews with the existing research in the field of Zero Trust. The results indicate that several barriers must be considered during the implementation phase. These include cost-related issues, lack of expertise, and outdated systems that cannot handle Zero Trust at the required security level. Despite these challenges, the respondents' attitudes towards Zero Trust were positive. They believed that it could be applied to sporadic and isolated parts of the network infrastructure, and that striving towards it at a theoretical level was essential.
