TL;DR: SCA false positives and weak severity ranking turn reachability into a poor stand-in for exploitability, according to Pixee. SCA workflows need contextual evidence before findings become actionable, or resolution debt and inconsistent remediation will keep growing.
Editorial analysis by NHI Mgmt Group, based on content published by Pixee: “Introducing Pixee for SCA”.
Key questions
Q: Why do false positives create such a large burden in SCA programmes?
A: False positives force teams into a bad trade-off: investigate too much and lose time, or investigate too little and miss real exposure.
Q: How can security teams tell whether an SCA triage workflow is actually working?
A: A triage workflow is working when it suppresses noisy findings without discarding true positives, and when reviewers can verify why a finding was accepted or dismissed.
Q: What breaks when SCA triage relies on reachability alone?
A: Reachability alone breaks because it can prove that code paths exist without proving that an attacker can use them in the real application.
Practitioner guidance
- Define exploitability criteria before triage starts Set explicit conditions that must be met before an SCA finding is treated as actionable, including application context, deployment state, and evidence of abuse paths.
- Separate reachability from exploitability in workflows Use reachability as an initial filter only, then require additional evidence before findings move into remediation queues or compliance reporting.
- Document the evidence behind every non-exploitable decision Record why a finding was classified as not exploitable so reviewers can verify the reasoning and avoid re-investigating the same issue repeatedly.
Bottom line: SCA breaks down when teams are forced to treat reachability as though it were proof of exploitability.

Exploitability, not reachability, is the decisive governance boundary in SCA. The article correctly separates a possible code path from a defensible security conclusion. That distinction matters because teams do not patch risk in the abstract, they patch conditions that can actually be abused in their environment. A triage process that cannot prove exploitability will either over-escalate noise or under-react to real exposure. The practitioner conclusion is simple: evidence quality must sit at the centre of vulnerability governance.
A question worth separating out:
Q: What should AppSec teams do first when dependency findings overwhelm the queue?
A: Start by defining the evidence required for a finding to count as exploitable, then make that evidence part of the triage gate. Once the gate exists, teams can separate low-confidence noise from issues that justify remediation, audit review, or escalation. Without that gate, every other improvement is just faster alert processing.
