The main benefit of using DevSecOps practices in software development is the integration of security into every phase of the development lifecycle. By fostering collaboration between development, security, and operations teams, DevSecOps ensures that security is prioritized alongside speed and efficiency. This proactive approach reduces vulnerabilities, accelerates compliance processes, and enhances overall software quality. Incorporating automated security testing and continuous monitoring streamlines workflows and reduces the risk of late-stage vulnerabilities in production environments, leading to more secure applications.
