AppSec vs. product security: Secure by Design demands a strategy shift

This article argues that achieving CISA’s Secure by Design vision requires evolving AppSec into holistic Product Security that embeds security from design through post-market operations, coordinates across R&D, quality, and SecOps, and evaluates software as a whole system rather than isolated components. Experts emphasize elevating product security leadership, integrating with DevOps and cloud environments, and adopting system-level assessment tools to ensure software integrity and resilience in real-world contexts.
