Three Reasons AST Is Evolving, Not Disappearing.

AI Demands More Testing, Not Less
AI is helping developers produce more code at higher velocity, but it still cannot reliably produce flaw-free code. AI moves AST from a periodic testing activity toward an always-on validation layer. AI-generated code can be created and changed continuously, and AI-driven remediation creates additional code changes that also need to be validated.

Finding Is Not Fixing. Fixing Is Not Validation.
To form an effective program, AST scan types are layered together with human pentesters and application security staff helping to remediate flaws. Simply trusting that AI can write flaw-free code or catch every flaw breaks the redundancy that forms the foundation of an AST program.
A Program, Not a Product
A real program means flaws get assigned, owned, remediated, certified, or accepted and recertified. This business process is the nexus of cooperation between development and security organizations, not merely a technology that is deployed. Veracode is one of the few vendors named in the report that delivers all seven components.
