DevOps and DevSecOps are both approaches that aim to improve the efficiency and speed of software development, but they have different focuses.

DevOps is an approach that aims to improve the collaboration and communication between development and operations teams in order to increase the speed and efficiency of software development and deployment. It emphasizes the use of automation and other tools to streamline the development process and improve the reliability and scalability of software.

DevSecOps, on the other hand, is an approach that builds on the principles of DevOps by adding a focus on security. It aims to integrate security practices and tools into the software development process, allowing for the identification and mitigation of security risks early in the development cycle. This approach can include practices such as code review, penetration testing, and automated security testing.

In summary, DevOps is focused on improving collaboration and efficiency in software development, while DevSecOps is focused on integrating security into the software development process to improve the security of the software.
