Objectives:
The article analyzes the Digital Services Act (DSA) and the Regulation on terrorist content online (TCO) as key instruments for combating illegal content in the European Union. The main objective of the text is to analyze how these regulations strengthen digital security while increasing the responsibility of online platforms and protecting users from threats such as radicalization, terrorism, crime, and disinformation.

Methods:
The study uses qualitative analysis based on legal provisions, European Union documents, and media reports. In order to assess the scope, mechanisms, and obligations imposed on both digital service providers and member states, these were discussed. The methodology combines source research and textual analysis, enabling an interdisciplinary assessment of the effectiveness of the regulations and the challenges associated with their implementation.

Results:
The results indicate that the DSA and TCO together form a comprehensive regulatory framework for combating illegal content on the Internet. The TCO introduces a rapid response mechanism, while the DSA provides broader systemic safeguards. Both pieces of legislation significantly strengthen user protection and platform responsibility, although some inconsistencies remain.

Conclusions:
The analysis shows that the combined regulatory framework is an important milestone in the European Union's digital policy. However, its long-term success depends on consistent enforcement across all Member States, adequate institutional capacity, and maintaining a balance between security objectives and fundamental rights.
