The relevance of the study is due to the simultaneous impact on the regional economy of the challenges of digital transformation and external sanctions pressure. The Republic of Dagestan, as a subject of the Russian Federation with a unique socio-economic structure, requires the adaptation of traditional approaches to assessing and ensuring economic security, taking into account new realities. The aim of the research is to develop an updated model for ensuring the economic security of the Republic of Dagestan, integrating digital tools and resilience to external shocks. The research uses methods of system analysis, comparative analysis, the method of economic security indicators, as well as the analysis of official statistics and strategic planning documents. The hypothesis of the study is that digital transformation, with targeted government support and reduced dependence on imported solutions, can act as a factor in increasing the stability of the regional economy and neutralizing key threats to its security. The scientific novelty of the study is to update the threshold values of economic security indicators for the Republic of Dagestan based on data from 2024-2025, as well as to identify the specifics of the interaction of digital technologies and sanctions restrictions in the context of regional sustainability. The results of the study include an updated map of threats to Dagestan's economic security, a quantitative assessment of the effectiveness of digitalization, as well as proposals for integrating the region into the new national program "Data Economics and Digital Transformation of the State." In conclusion, the necessity of forming a three–tier system of ensuring economic security is substantiated – at the level of households, enterprises and regional authorities - with an emphasis on developing their own digital competencies and reducing technological dependence.
