In my opinion, a DevSecOps Maturity Model is very useful because it gives organizations a clear roadmap for improving security practices in a structured and measurable way rather than relying on scattered or reactive efforts. It helps teams understand their current security posture, identify gaps, and prioritize improvements across development, operations, and compliance processes. By defining maturity levels, companies can gradually move from manual security checks to automated and continuous security practices that fit modern delivery pipelines. The first areas companies should prioritize are secure coding awareness, integrating basic security scanning into CI/CD pipelines, dependency and vulnerability management, access control, and clear collaboration between development, operations, and security teams. After that, they can focus on advanced areas like policy automation, continuous compliance, threat detection, and real-time monitoring. Overall, the maturity model is valuable because it turns security improvement into a practical journey with clear milestones instead of an overwhelming one-time goal.
