The integration of digital knowledge and information technology into all economic sectors is driven by the digital revolution and Industry 4.0. They also emerge as the primary driver of economic advancement across different nations. The main research goal of this paper is to analyse how the Digital Development Level influences the National Cybersecurity Index across different countries, as well as to determine the average Digital Development Level and the average National Cybersecurity Index value for all countries. A quantitative approach was employed in this research, utilizing secondary data. The analysis included one-way ANOVA, linear regression, correlation, and descriptive statistics. The study found a positive correlation between the Digital Development Level (DDL) and the National Cybersecurity Index (NCSI), as well as significant disparities between these variables. Qualitative factors, such as government policies, organizational culture, or international cooperation, are not accounted for in the analysis. Research results highlight the need for continued investments in both areas and underscore the importance of integrated policy approaches that address the complex challenges of the digital economy.

The article substantiates the existence of convergence processes in the field of digitization of countries, taking into account the number of Internet users; people with advanced skills; and indicators of infrastructure (network coverage, population covered by at least a 3G mobile network, population covered by at least a 4G mobile network), access (access to ICT at home, active mobile broadband subscriptions, fixed broadband subscriptions), enablers (fixed broadband over 10 Mbps, mobile data and voice basket, high consumption) and barriers (improved broadband access from 256 kbps to 2 Mbps and from 2 Mbps to 10 Mbps mobile data and voice basket, low consumption) of digital development. The methodological basis for determining the sigma convergence of digitization processes is the coefficient of variation. The values of the coefficient of variation confirmed the high level of convergence between the studied countries in terms of the degree of use of the Internet for conducting digital transactions. The developed econometric model, which describes the influence of statistically significant integral indicators of the national cybersecurity level, ease of doing business, and the anti-money laundering index on the country's digital development level, made it possible to determine the average trend of dependence on the level of digital development. One hundred four countries were considered for the analysis. The conducted study of the impact of digitalization on economic transformations based on developed quantile regressions made it possible to analyze exactly how the level of digital development for countries with a high level of digitalization and for countries with a low level of digitalization development depends on the value of the national cybersecurity indicator and the ease of doing business, and which countries have the least resistance to the risk factors of their involvement in fraudulent schemes for the purpose of legalizing criminal income.
