TL;DR: AppSec ROI changes when validation and remediation move into the IDE, where AI-assisted coding makes late-stage scan-and-fix workflows slower, more expensive, and harder to govern, while inline fixes reduce MTTR, rework, and false-positive drag, according to Checkmarx. The shift matters because security value now depends on control placement at the point of creation, not after the commit.

Questions worth separating out
Q: How should security teams reduce rework when AI accelerates code changes?
A: They should move security checks closer to authoring time, because the cost of fixing issues rises sharply after merge.
Q: Why do AI-assisted development workflows change AppSec ROI calculations?
A: They change ROI because faster code creation makes delayed remediation more expensive.
Q: What do security teams get wrong about false positives in code scanning?
A: They treat false positives as a nuisance metric instead of a control-quality signal.
Practitioner guidance
- Shift high-confidence remediation into the IDE Prioritise controls that let developers fix validated issues while the code context is still open, then reserve downstream review for exceptions and higher-risk cases.
- Track rework cost alongside vulnerability counts Measure PR rewrites, pipeline reruns, and review loops as first-class cost indicators so finance and engineering can see the real impact of late discovery.
- Separate noisy findings from enforceable controls Classify findings by confidence and operational impact, then tune workflows so low-value alerts do not consume the same developer path as actionable issues.

Agentic AppSec in the IDE: what changes for ROI and governance?

AppSec ROI now depends on intervention timing, not just detection volume. When code generation is accelerated by AI, the value of a security control is determined by whether it acts before merge or after release. Late-stage scanning still has value, but it cannot by itself offset the rework created by fast-moving delivery pipelines. The practical conclusion is that control placement has become a governance issue, not only an engineering one.
A few things that frame the scale:
- The average estimated time to remediate a leaked secret is 27 days, despite 75% of organisations expressing strong confidence in their secrets management capabilities, according to The State of Secrets in AppSec.
- Only 44% of developers are reported to follow security best practices for secrets management, exposing a significant developer behaviour gap.
A question worth separating out:
Q: How do identity and secrets governance intersect with agentic AppSec?
A: They intersect because AI-driven development still depends on credentials, tokens, and service identities to access code, pipelines, and deployment systems. If those identities are validated only after use, the exposure window widens. The same control logic that supports inline AppSec also supports stronger NHI governance.
