TL;DR: Late discovery of code flaws can cost 3 to 14 times more to fix than catching them early, according to Sonar, as the article argues for continuous security checks across commits, pull requests, builds, AI-generated code, and open source dependencies. The governance shift is from end-of-cycle review to always-on quality gates that reduce rework and shorten remediation cycles.
NHIMG editorial — based on content published by Sonar: shift-left code security across modern pipelines
By the numbers:
- Fixing issues late in the development lifecycle can make security costs 3 to 14 times higher than catching them early.
Questions worth separating out
Q: How should teams implement code security controls in CI/CD pipelines?
A: Teams should place automated checks at commit, pull request, and build stages so insecure code never becomes a release candidate.
Q: Why do AI-generated code changes increase application security risk?
A: AI-generated code can increase risk because it accelerates output faster than review, testing, and secret hygiene can keep up.
Q: What do security teams get wrong about secrets in generated code?
A: They often assume secret scanning alone is enough.
Practitioner guidance
- Embed security checks into pull requests and builds Require automated security and quality gates before merge so developers fix issues while the code context is still fresh.
- Extend policy coverage to AI-generated code Review generated code with the same approval standards used for human-written code, including secrets exposure, injection patterns, and unsafe dependencies.
- Scan for secrets in every code path Search source repositories, build logs, and pipeline artifacts for credentials, tokens, and certificates.

Shift-left code security is now a governance model, not a tooling preference. The article makes the case that security must be embedded into every commit, pull request, and build, which reflects a broader shift in how engineering controls are enforced. The relevant framework lens is NIST CSF protect and detect functions, plus OWASP Non-Human Identity Top 10 where secrets and automation credentials appear in code. The practitioner conclusion is simple: if security only appears at the end of the lifecycle, it is already too late to shape risk.
A question worth separating out:
Q: When should organisations prioritise shift-left security over late-stage review?
A: They should prioritise shift-left security whenever the cost of remediation, release delay, or customer exposure rises after code leaves the developer workflow. Once defects reach staging or production, fixes become slower and more disruptive. Early enforcement is the better control when speed, trust, and compliance all matter.
