Fraud Detection Thresholds

Velocity Detection

Velocity Threshold Transactions per 10m

3

Block if user makes more than this many transactions in 10 minutes

ML Model Thresholds

High Risk Threshold 0.0 - 1.0

0.9

Probability above this → Block

Flag Risk Threshold 0.0 - 1.0

0.8

Probability between flag and high risk → Flag for review

Amount Detection

Amount Spike Multiplier x times baseline

3.0x

Block if amount exceeds user baseline by this multiplier

Baseline Amount $

$ $1500

Reference amount for calculating spikes

Anomaly Detection

Anomaly Score Threshold 0.0 - 1.0

0.03

Flag if Isolation Forest anomaly score exceeds this

Configuration Presets

STRICT (High Security)

Maximum fraud detection - tolerates false positives

• Velocity: 2 txn/10m • Risk threshold: 0.7 • All checks enabled

BALANCED (Recommended)

Moderate fraud detection with acceptable false positives

• Velocity: 3 txn/10m • Risk threshold: 0.8 • All checks enabled

LENIENT (Low Friction)

Minimal fraud detection - prioritizes user experience

• Velocity: 5 txn/10m • Risk threshold: 0.9 • Only critical checks enabled
