The paper is devoted to the investigation of environmental, energy and economic security by multivariate analysis methods. A set of indicators selected for research conducting includes 9 parameters for each security type. Study sample is formed by data for 6 Eastern European countries (Ukraine, Moldova, Poland, Romania, Hungary and Slovak Republic) for the period 2000–2019. Empirical study was conducted by factor analysis, which allowed identifying the main components of environmental, energy and economic security. Comparison of the results obtained for the studied countries showed differentiation of individual profiles of such types of security. Investigation of integral vectors of environmental, energy and economic security showed the highest level of interaction between energy and environmental security and the lowest one between energy and economic security.
