The article is devoted to the study of the toolkit, with the help of which it is possible to optimize the administrative and legal provision of the security sector of Ukraine. Attention is focused on the fact that administrative and legal support outlines the boundaries of the subject structure of regulatory activity in such a way that it can be carried out not by any state bodies, but only by those that perform powerful public management functions. Subjects of administrative and legal support of the security sector include: 1) those that manage the security sector; 2) those that are part of the security sector and implement separate measures aimed at the proper state of national security.
 It has been established that the toolkit of administrative and legal provision of the security sector is a set of methods, techniques and methods used by authorized entities to regulate social relations, the content of which is aimed at protecting state sovereignty, territorial integrity, the democratic constitutional order and other national interests of Ukraine from possible threats.
 The toolkit of administrative and legal provision of the security sector is classified according to the following criteria: 1) depending on the subject of application; 2) depending on the form of external fixation; 3) depending on the direction of action; 4) depending on the object to be secured; 5) depending on the time of application, etc.
 Attention was drawn to the need to optimize the tools of administrative and legal provision of the security sector. The importance of the implementation of digital technologies in the activities of specially authorized entities in the field of security is analyzed. It is noted that the peculiarity of the security sector determines the additional need for prompt response to emerging threats and the use of flexible mechanisms for their elimination. It is proposed to amend the legislation by establishing the possibility of making decisions by the National Security Council in the form of directives that do not require additional implementation through the adoption of a corresponding decree by the President of Ukraine, are of general obligation and are adopted during the period of the legal regime of martial law.
