TL;DR: AI-generated code is shortening the time between defect introduction and exploitability, Checkmarx reports, and that speed makes traditional review cycles less reliable. Development teams need controls that act earlier, because late findings arrive after the best chance to stop risk.
Editorial analysis by NHI Mgmt Group, based on content published by Checkmarx: “Guardrails for Agentic Development”.
Key questions
Q: Why do AI coding workflows require security decisions earlier in the lifecycle?
A: Because continuous generation removes the natural pauses that traditional security gates depend on.
Q: What are the signs that AppSec controls are failing under AI code velocity?
A: Common signs include growing review backlogs, more vulnerabilities appearing in generated code, slower remediation than release cadence, and repeated fixes for the same classes of flaws.
Q: What breaks when AI-assisted coding outpaces AppSec review cycles?
A: Manual triage and blanket scanning lose effectiveness when code volume rises faster than security capacity.
Practitioner guidance
- Embed security checks into the coding workflow Run analysis at code creation and pull request stages so generated code is reviewed before it reaches shared branches or deployment pipelines.
- Separate prevention from enforcement decisions Use one control layer to catch insecure patterns early and another to score exploitability, exposure and runtime context before approval.
- Inventory AI coding tools and automation identities Maintain ownership, purpose, permission scope and approval status for every AI coding tool, agent and automation service that can change code or trigger workflows.
Bottom line: AI-generated code compresses the window between defect introduction and deployment, which breaks review models built around slower release cycles.

AI-generated code has turned appsec into a capacity problem, not just a detection problem. The central issue is no longer whether teams can identify weak code, but whether they can make security decisions fast enough to keep pace with generation. When review capacity lags behind code creation, risk accumulates in the queue rather than in the scanner. The practitioner conclusion is to redesign control points around flow, not volume.
A question worth separating out:
Q: How should organisations govern tool approvals in AI coding workflows?
A: They should treat each approval as a privileged event with identity binding, context, and retention. That means recording who approved the action, what tool was used, where the action went, and whether the request matched policy before execution completed.
