MeshFin Detect
Fraud and scam detection and response
Every transaction and session scored in real time with an explanation, alerts assembled with the history and the similar cases, customers contacted and funds held or recovered through the rails, and the models watched for drift, bias and false positives.
MeshFin Detect (MF-16), the service for fraud and scam detection and response, is one of the twenty-four MeshFin services, in the "Managing risk and compliance" family, which follows the BIAN Risk and Compliance business area. It covers the BIAN service domains Fraud Evaluation, Fraud Diagnosis, Fraud Resolution, Fraud Model and Transaction Authorization in whole or in part. Every transaction and session scored in real time with an explanation, alerts assembled with the history and the similar cases, customers contacted and funds held or recovered through the rails, and the models watched for drift, bias and false positives. It replaces fraud rules engine bolt-on, alert queue, scam reporting spreadsheet and model monitoring by quarterly report. AI agents carry the work end to end; a named person takes every decision with legal or financial effect on a customer, the balance sheet or a regulatory obligation. It is core for a universal and retail bank, core for a mutual and community bank, core for a non-bank lender and fintech.

The agents that carry it
Scoring agent
Scores each transaction and session in real time against the models and the rules, with the reason recorded for every score.
Alert agent
Assembles the alert pack: history, device, counterparty, similar cases, and recommends hold, release or contact.
Response agent
Contacts the customer, holds the payment, attempts recovery through the rails where the rules allow, and files the industry report.
Model agent
Monitors drift, false-positive rates and bias across the models, and prepares the retraining case with the evidence.
Where a person decides
No decision with legal or financial effect on a customer, the balance sheet or a regulatory obligation is taken by an agent alone. In MeshFin Detect, these decisions are held for a named person, with the agent's evidence and recommendation attached.
| Decision | Who decides | Why a person |
|---|---|---|
| Freezing or closing an account | Fraud officer | Legal effect on a person |
| Reimbursement under the scams code | Delegated officer | Financial effect, contestable |
| Model change into production | Model risk delegate | Model risk policy |

Questions banks ask about MeshFin Detect
- What does MeshFin Detect do?
- MeshFin Detect is the MeshFin service for fraud and scam detection and response. Every transaction and session scored in real time with an explanation, alerts assembled with the history and the similar cases, customers contacted and funds held or recovered through the rails, and the models watched for drift, bias and false positives. It reacts to events such as transaction or session scored, customer reports a scam and mule-account pattern detected, and writes alert with explanation, hold and release log, reimbursement decision and model change record as records.
- Which BIAN service domains does MeshFin Detect cover?
- Fraud Evaluation, Fraud Diagnosis, Fraud Resolution, Fraud Model and Transaction Authorization, in the BIAN Risk and Compliance business area, in whole or in part. The mapping is to the published BIAN Service Landscape; BIAN has not reviewed or endorsed MeshFin.
- What systems does MeshFin Detect replace?
- Fraud rules engine bolt-on, Alert queue, Scam reporting spreadsheet and Model monitoring by quarterly report. Because the service runs on the MeshFin platform, the licence, integration and upgrade costs of those systems retire with them.
- What do the AI agents do in fraud and scam detection and response?
- The scoring agent scores each transaction and session in real time against the models and the rules, with the reason recorded for every score. The alert agent assembles the alert pack: history, device, counterparty, similar cases, and recommends hold, release or contact. The response agent contacts the customer, holds the payment, attempts recovery through the rails where the rules allow, and files the industry report. The model agent monitors drift, false-positive rates and bias across the models, and prepares the retraining case with the evidence.
- Which decisions does a person still take?
- Agents never take a decision with legal or financial effect on a customer, the balance sheet or a regulatory obligation. In MeshFin Detect, a person decides freezing or closing an account (fraud officer), reimbursement under the scams code (delegated officer) and model change into production (model risk delegate). The record shows who decided, why, on what evidence and under which delegation.
