Build a Fraud Feedback Loop Your ATS Can Actually Audit
Fraud controls that do not learn from confirmed cases decay fast. This briefing shows how Recruiting Ops can run an SLA-bound feedback loop that improves detection while staying audit-ready and legally defensible.

A fraud control that does not learn from confirmed cases is a control with a known expiration date.Back to all posts
What breaks when fraud is not fed back
Recommendation: run fraud response like an incident loop with evidence packs, not like one-off investigations. If a candidate clears your funnel and later turns out to be a false identity, the damage is not just the miss. It is the absence of a defensible narrative: who approved the candidate, what evidence existed at the time, and what controls were executed before privileged steps. Checkr reports 31% of hiring managers say they have interviewed a candidate who later turned out to be using a false identity. That volume is enough to overwhelm manual review unless you instrument a feedback loop with SLAs and clear owners. Replacement cost is a budget event. SHRM estimates replacing an employee can cost 50-200% of annual salary depending on role. Late-stage fraud multiplies that cost by adding cycle-time waste and offer fallout.
Time-to-offer spikes at stages where identity is unverified.
Review queues age because no one owns labeling SLAs.
Evidence is fragmented, so Legal review becomes a fire drill.
Why legacy tools fail to create a feedback loop
Recommendation: stop trying to "connect" siloed tools with spreadsheets. You need an ATS-anchored audit trail with immutable evidence references. Legacy ATS workflows optimize for moving candidates forward, not for capturing chain-of-custody. Verification happens after access, assessments log activity but not standardized rubrics, and background checks arrive as PDFs that do not map to hiring-stage events. The common failure modes are operational: sequential checks that slow everything down, no unified evidence packs, no review-bound SLAs, and shadow workflows that turn labeling into chat messages. If it is not logged, it is not defensible.
Who owns the fraud feedback loop and what is the system of truth
Recommendation: assign owners by control type and define one system of record for each artifact class. Recruiting Ops owns the workflow and SLA mechanics. Security owns policy, thresholds, and audit rules. Hiring Managers own rubric discipline and timely notes. Analytics owns dashboards and drift monitoring. Sources of truth must be explicit: ATS for stage history and decision narrative; verification and assessment layers for evidence artifacts; and a case queue for labeling decisions and appeals, all linked by evidence pack ID.
Automate signal capture, routing, write-backs, and policy enforcement.
Manually confirm fraud labels and handle appeals with a second-review path.
Never manually "label" in side channels. Labels must be case events with approver identity and timestamps.
What is a modern fraud feedback loop in hiring
Recommendation: design the loop as Detect - Triage - Confirm - Learn - Deploy - Monitor, with timestamps at every hop. Identity gating before access reduces the blast radius. Event-based triggers reduce reviewer fatigue by routing only candidates with concrete anomalies. Automated evidence capture produces a defensible record. Dashboards surface where SLA breaches and fraud leakage occur. Standardized rubrics prevent unstructured notes from becoming your only evidence.
If mismatch-to-ID or liveness anomaly occurs, require step-up verification before any live interaction.
If proxy interview indicators occur during screening, pause and route to Security review within SLA.
If candidate appeals, run second review with fresh verifier, and log overturns as false positive signals.
Where IntegrityLens fits in the loop
IntegrityLens AI provides an ATS plus identity and assessment controls that keep the fraud loop closed and auditable, not scattered. It enforces identity verification before access, captures fraud signals as timestamped events, and produces immutable evidence packs linked to ATS-anchored audit trails. It supports 24/7 AI screening interviews with structured rubrics and technical assessments with execution telemetry, so the feedback loop trains on evidence, not vibes.

Identity gating: liveness, document authentication, face match before privileged steps.
Defense in depth: deepfake detection, proxy interview detection, behavioral signals captured as events.
Evidence packs: tamper-resistant artifacts and notes tied to reviewer identity and timestamps.
ATS write-backs: stage changes and decisions recorded in one system of truth.
Risk-tiered funnel: step-up verification when signals warrant it.
Anti-patterns that increase fraud exposure
Allowing interviews or assessments before identity is verified.
Storing evidence in Slack, email, or spreadsheets instead of evidence packs.
Implementation runbook with SLAs, owners, and evidence
Recommendation: treat each suspected fraud case like a ticket with an SLA, an owner, and an evidence pack ID. Run the loop weekly for dataset cuts and monthly for model or policy updates. If you cannot commit to that cadence, your loop will silently rot. Below is a policy template that Recruiting Ops can operationalize and Security can audit.
Initial triage: 4 hours business time
Step-up request after triage: 2 hours
Fraud confirmation decision: 2 business days
Weekly dataset cut: every Friday 17:00 local
Monthly release window: first Tuesday, with rollback plan

Defensible decisions because approvals, artifacts, and timestamps are retrievable.
Lower fraud exposure through a risk-tiered funnel and continuous learning loop.
More consistent scoring across teams because rubrics and evidence are standardized.

Key takeaways
- Treat fraud detection like access management: identity gate before any privileged step (interview, assessment, offer).
- Only retrain on confirmed outcomes with a documented chain of custody. Unlabeled suspicion creates legal and model risk.
- Put SLAs on labeling, review, and policy updates. If the loop is not time-bound, it will not run.
- Separate detection signals from decision evidence. Evidence packs are what you defend; signals are what you tune.
- False positive management is a first-class control: step-up verification and second-review queues reduce wrongful accusations.
Use this as the minimum viable policy Recruiting Ops can run weekly. It forces chain-of-custody, prevents training on unconfirmed suspicion, and makes false positive management explicit.
Store this policy version ID in the ATS and reference it in every evidence pack created under it.

Outcome proof: What changes
Before
Suspected fraud was handled ad hoc in Slack and email. Verification artifacts were not consistently linked to the ATS record, and triage had no SLA owner. Late-stage reversals repeatedly reset time-to-offer and created inconsistent decision narratives.
After
A single triage queue with SLAs was introduced, identity gates were enforced before privileged steps, and every case produced an evidence pack ID written back into the ATS. Confirmed labels were used for weekly dataset cuts, while inconclusive cases were excluded from training and routed to step-up verification.
Implementation checklist
- Define fraud taxonomies and confirmation criteria that Legal will defend.
- Instrument your funnel with immutable event logs and evidence pack IDs.
- Create an SLA-bound review queue for suspected fraud and candidate appeals.
- Gate interviews and assessments behind step-up verification when risk signals trigger.
- Ship model updates on a scheduled cadence with versioned policies and rollback.
- Measure time-to-event deltas and fraud leakage by stage, not anecdotes.
Questions we hear from teams
- What is a fraud feedback loop in hiring?
- A fraud feedback loop is an SLA-bound process that converts confirmed fraud and cleared cases into labeled, time-stamped training signals and updated policies, with every decision linked to an evidence pack ID in the ATS.
- Why not retrain on all suspicious cases?
- Suspicion is not a defensible label. Training on unconfirmed cases increases false positives and creates legal exposure because you cannot justify why a candidate was treated as fraud without confirmed criteria and chain-of-custody evidence.
- How do you manage false positives without slowing hiring?
- Use step-up verification and second-review only when concrete signals trigger, and enforce triage SLAs. This keeps the high-trust funnel moving for low-risk candidates while creating a defensible process for exceptions.
- What should be logged for audit readiness?
- At minimum: trigger signal, timestamps, reviewer assignment, verification outcomes, rubric scores, decision reason codes, approver identity, evidence pack ID, and policy or model version at time of decision.
