Challenges and Future Scope

In the same Fortinet survey, firms mentioned additional difficulties they encountered when implementing zero trust. The majority, 59%, found it difficult to continuously authenticate users and devices and to monitor users once they had done so (54%). Concerns were also raised by the absence of cloud and on-premises integration (33%). A cybersecurity strategy known as the “Zero Trust Model” implies no implicit trust for any person, system, or device regardless of whether they are a part of the company network. Although this strategy improves security, there are a number of issues with it (Teerakanok et al. in Security and Communication Networks 2021:1–10, 2021)(Buck et al. in Computers & Security 110, 2021).
