The objective of the article was to determine how effective international institutions are in the mechanism for the protection of human rights and freedoms in the context of national security. The methods of statistical analysis, correlation analysis, generalization and analogy, hypothetical-deductive model were used to achieve the proposed objective. In addition, international institutions were identified that are directly concerned with the protection of rights and freedoms in the event of their violations at the regional level. The correlation was established between the level of human rights protection and the level of national security, the number of international human rights treaties ratified, the number of cases brought before international regional human rights courts.
