In the face of the global trend driven by governments and key infrastructure industries advocating for the Zero Trust security framework, enterprises often grapple with avoiding mere compliance, aligning with trends, or making investments without clear direction. Leveraging CISA's Zero Trust maturity assessment criteria and NIST CSF framework, the Systex Group Cybersecutiry team & uniXecure Tech. Ltd integrate years of practical cybersecurity experience. We introduce a pioneering 'Zero Trust Maturity Assessment Methodology,' offering insights from real-world implementations within the group. This approach enables organizations across various industries to balance theoretical and practical aspects of cybersecurity. Collaboratively aligning information infrastructure, networks, application development, and cybersecurity teams with a shared understanding, we help craft phased Zero Trust security implementation plans that effectively garner support from top management.
