AppSec maturity models are tools that help organizations measure their current security posture, identify areas for improvement, and set goals for growth. These models provide a standardized framework for assessing application security initiatives, allowing teams to tailor their approach to fit their needs and growth goals. By using an AppSec maturity model, organizations can clarify what "success" looks like for their teams' application security initiatives, provide clear standards for the entire organization, and ensure that the program covers the entire application library and SDLC process. Various models exist, including OWASP Software Assurance Maturity Model (SAMM), Building Security In Maturity Model (BSIMM), and Cybersecurity Maturity Model Certification (CMMC). The choice of model depends on the organization's specific industry or geographical location. To measure application security maturity, organizations can use tools to automate processes, conduct periodic assessments, decide which core points apply most to their organization, view the process as an ongoing project, and monitor progress with an ASPM tool such as Snyk AppRisk.
