TL;DR: 100 wrong verdicts a day shows how incomplete evidence can drive AI SOC misdispositions, in D3's case work on AI SOC triage. Evidence gaps can look clean unless the workflow records what was not retrieved.
Editorial analysis by NHI Mgmt Group, based on content published by D3: “100 Wrong Verdicts a Day: The Fine Print Inside a “99% Accurate” AI SOC”.
Key questions
Q: Why does incomplete evidence create more risk than model hallucination in SOC triage?
A: Because hallucination is visible noise, while incomplete evidence can produce confident false closure that looks operationally clean.
Q: How do organisations know if AI triage is actually working?
A: Measure whether the AI improves high-fidelity detection, shortens time to verified response, and preserves reviewer trust in its decisions.
Q: What breaks when AI SOC triage cannot distinguish missing evidence from clean evidence?
A: The workflow can close real incidents as benign because the model treats incomplete context as if it were a complete negative.
Practitioner guidance
- Implement an explicit evidence ledger Record every queried source, success or failure, and response completeness before any AI disposition can close an alert.
- Type missing data distinctly Use separate states for checked and not found, checked and unavailable, and not checked so the model cannot collapse them into one empty result.
- Block auto-closure on incomplete coverage Require the orchestration layer to keep alerts open whenever any expected source failed or was never reached.
Bottom line: AI SOC failure is more often a problem of incomplete evidence than of fabricated output, which means disposition logic matters as much as model quality.

Missing evidence is the real hallucination problem in AI SOC. The failure is not that the model invents facts, but that it is asked to complete a pattern over an incomplete evidentiary record. That makes the governance gap a retrieval and disposition problem, not a language-model problem. Practitioners should therefore judge AI SOC tools by how they preserve absence, not by how fluently they explain a verdict.
A few things that frame the scale:
- AI-related credential leaks surged 81.5% year-over-year in 2025, with the surrounding AI infrastructure leaking 5x faster than core LLM providers, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: Should organisations use fail-open or fail-closed logic for AI SOC alerts?
A: Fail-open logic is safer for triage because it preserves uncertainty and hands incomplete cases to analysts. Fail-closed logic can silently dispose of live threats when the model has too little evidence to make a defensible call.
