TL;DR: AI adoption in development is outrunning security programs, creating a predictable progression from shadow use and late cleanup to inline enforcement and audit-ready governance, according to LEGIT Security. The real inflection point is when teams stop treating AI-generated code as a detection problem and start governing it at generation time.
NHIMG editorial — based on content published by LEGIT Security: The AI Security Maturity Model for AI-First Development Teams
Questions worth separating out
Q: What breaks when AI-generated code is only checked after commit?
A: Post-commit checking creates a rework loop.
Q: Why do AI coding tools complicate governance and auditability?
A: AI coding tools complicate governance because teams can adopt them informally, outside central visibility and approval.
Q: How do security teams know if AI governance is working?
A: Look for evidence that access decisions are reviewable, permissions are revocable, and exceptions are not becoming permanent.
Practitioner guidance
- Inventory AI tool usage across development teams Survey developers to identify which AI tools are in use, how often they are used, and which tasks they support, then map that data to repositories and business units.
- Move policy checks earlier in the SDLC Deploy pre-commit hooks, IDE controls, or endpoint integrations that stop secrets, license issues, and critical policy violations before code reaches the repository.
- Track policy drift between written rules and enforced controls Compare documented AI code policies with actual scanner settings, developer workflows, and exception handling across teams.
What's in the full article
LEGIT Security's full article covers the operational detail this post intentionally leaves for the source:
- Stage-by-stage self-assessment questions for placing a team on the maturity curve
- Concrete examples of the controls expected at each stage, from repository scanning to inline guardrails
- A 90-day rollout plan that sequences assessment, pilots, scaling, and measurement
- The article's own product and implementation context for teams evaluating AI governance tooling

Shadow AI creates a governance problem before it creates a code-quality problem. The article shows that unmanaged AI use begins with a visibility gap, not a technical failure in the code itself. That gap matters because governance only becomes credible when the organisation can identify which tools, workflows, and outputs exist. For programmes that also manage secrets and machine access, the same pattern appears whenever controls are built after usage spreads. Practitioner conclusion: establish authoritative visibility before treating AI-assisted development as a controllable security domain.
A question worth separating out:
Q: Who is accountable when an AI coding tool introduces insecure code into production?
A: Accountability stays with the organisation that allowed the tool to operate without enforced guardrails. The model is not the accountable party. Security, engineering, and platform owners share responsibility for defining policy, enforcing it at runtime, and logging the decision trail that proves controls were applied.
