DevSecOps emerged to mitigate the challenges of integrating security into DevOps. DevOps have grown tremendously, leading to difficulties in integrating security tools in its development process while maintaining speed and agility. This study aims to investigate the security tools in DevSecOps and how they have been reported in previous literature. The main objective of this study is to provide a knowledge base concerning security tools in DevSecOps that can be used to mitigate challenges regarding the selection and use of security tools in the context of DevSecOps. A systematic literature review was adopted for the research. The study collected a total of  228 studies published between 2015 and 2022; fourteen of these papers were selected to be used for data extraction after conducting a thorough review protocol.

This study has identified thirteen security tool categories used or recommended to be used in DevSecOps. These tools have been structured into seven phases of the development process and five security practices. Additionally, this study has identified twelve drawbacks and sixteen recommendations concerning the use of these security tools in DevSecOps. 

The security tools categories, recommendations, and drawbacks identified in this study could potentially be used to facilitate the challenges of selecting and using security tools in DevSecOps and similar methodologies that rely on automation and delivering software frequently.
