RiskOS™ Dashboard Setup

Set up Sigma Synthetic Fraud in the RiskOS™ Dashboard

Before you start

Make sure you have the following:

How it works

Sigma Synthetic Fraud is a fraud detection enrichment available in RiskOS™. It evaluates identity attributes against consortium data to identify signals associated with synthetic identity fraud.

Sigma Synthetic Fraud returns:

• Model scores: Normalized synthetic fraud risk scores generated by one or more models.

• Reason codes: Indicators that explain the contributing factors behind synthetic risk signals.

These outputs can be used to inform routing, step-up verification, review, or escalation decisions in your workflows.

How Sigma Synthetic Fraud fits into a workflow

In RiskOS™, workflows are built by connecting reusable components. Sigma Synthetic Fraud is added as an Enrichment step.

Once the enrichment runs, its outputs are available to downstream workflow components, including:

• Conditions
• Decision rules
• Rule score cards
• Manual review steps
• Final decisions

For more detail on these components, see Workflow Steps.

Execution flow in RiskOS™

Sigma Synthetic Fraud runs synchronously as part of a RiskOS™ workflow. There is no user handoff or pause in execution.

    B[Sigma Synthetic Fraud]
    C[Routing logic]
    D[Decision]

    A --> B --> C --> D

At a high level, the execution flow looks like this:

1. Input
   You call the Evaluation API with identity attributes.

2. Sigma Synthetic Fraud enrichment
   RiskOS™ evaluates the provided attributes and returns model scores and reason codes.

3. Routing logic
   The workflow evaluates synthetic fraud scores and reason codes.

4. Decision
   The workflow returns a final outcome (for example, Accept, Review, or Reject).

Workflow components used by Sigma Synthetic Fraud

Sigma Synthetic Fraud uses a subset of standard RiskOS™ workflow components.

Configure Sigma Synthetic Fraud

Add Sigma Synthetic Fraud to a workflow

1. In the RiskOS™ Dashboard, go to Workflows and create a new workflow or open an existing one.
2. On the workflow canvas, select the plus (+) icon.
3. Add an Enrichment step and select Sigma Synthetic Fraud.

After the enrichment is added, its outputs can be referenced by downstream workflow logic.

Configure routing using model scores

Sigma Synthetic Fraud returns one or more model scores under:

socure_sigmasynthetic_response.synthetic.scores

Each score object includes:

• score: Normalized risk score between 0.001 and 0.999
• name: Model name
• version: Model version identifier

Using a single score

If your integration is configured to return a single model score, you can reference it directly when defining Conditions in your workflow, for example:

socure_sigmasynthetic_response.synthetic.scores.0.score

Customers typically define thresholds based on their own risk tolerance and downstream verification strategy. For integrations that receive only a single score in the response, Conditions can be added directly against socure_sigmasynthetic_response.synthetic.scores.0.score. A common starting thresholds is 0.99 for step-ups to eCBSV or Document Verification.****

Using multiple scores

If multiple model scores are returned, do not rely on the position of a score within the array. Instead, Conditions should evaluate both the score value and the associated model version.

For example, to evaluate whether a specific model version meets a given threshold, construct Conditions that:

• Check the score value, and
• Confirm the corresponding version field matches the intended model

This may require evaluating more than one element in the scores array, depending on your configuration.

Configure routing using reason codes

Reason codes are returned under:

socure_sigmasynthetic_response.synthetic.reasonCodes

This field contains an array of strings (for example, "R220") that explain contributing synthetic risk signals.

You can route based on reason codes by:

1. Adding a Condition step
2. Selecting the variable socure_sigmasynthetic_response.synthetic.reasonCodes
3. Choosing array contains or array does not contain
4. Providing the reason code value in quotes

Refer to the RiskOS™ Dashboard for the list of reason codes available for Sigma Synthetic Fraud.

Save and publish

Once your workflow is configured, publish it to go live.
