Key Benefits
- 70% reduction in false positives compared to traditional rule-based systems
- Real-time detection with average latency under 2.3 seconds
- 99.8% AI accuracy in identifying fraudulent patterns
- 340% ROI in the first year through loss reduction and process optimization
- Immutable audit trail guaranteed by permissioned blockchain technology

Application for Intesa Sanpaolo
Guardian AI has been designed to integrate seamlessly with Intesa Sanpaolo's existing systems, ensuring full compliance with European regulations (6AMLD, GDPR, PSD2), integration with core banking systems and existing AML platforms, scalability to handle enterprise-level transaction volumes, and multi-channel and multi-language support for international operations.
2. The Problem: The Challenge of Modern Banking Fraud
2.1 Current Scenario
The landscape of financial fraud is constantly evolving. Criminals use increasingly sophisticated techniques, leveraging:
- Cryptocurrencies and digital assets to complicate tracing
- Tax havens and non-cooperative jurisdictions to conceal money flows
- Transaction fragmentation (smurfing) to evade reporting thresholds
- Synthetic identities and deepfakes to bypass KYC controls
- Instant transaction speed which reduces the intervention window
2.2 Limitations of Traditional Systems
Static Rule-Based Approach
- Unable to adapt to emerging fraudulent patterns
- Generate high false positive rates (60-80% of cases)
- Require costly and slow manual updates
Lack of Real-Time Context
- Analysis limited to predefined parameters
- Inability to evaluate customer behavior over time
- Absence of correlation with external intelligence sources
2.3 Economic Impact
Industry Data (2024-2025):
- Direct fraud costs: €12.3 billion in Europe
- AML operational costs: Banks spend an average of €500M/year on compliance
- Regulatory sanctions: €2.8 billion in AML fines in 2024
- Time dedicated to false positives: 73% of AML team resources
- Average cost per false positive: €1,200 - €2,500 per investigation
For an institution the size of Intesa Sanpaolo, this translates to approximately 450,000 AML alerts/year, 80,000 man-hours dedicated to analysis, and estimated operational costs of €180-250 million/year.

Scenario:
A customer (public employee with declared income €35K/year) makes a SWIFT transfer of €847,250 to an offshore company in Hong Kong, first transaction to this beneficiary.
Guardian AI Process:
- Ingestion (t=0ms): Transaction intercepted by Real-Time Monitoring Engine
- Feature Engineering (t=50ms): Customer profile loaded, transaction history analyzed
- AI Scoring (t=120ms): Risk Score: 94/100 (CRITICAL), Confidence: 98.7%
- Alert Generation (t=150ms): Alert created with CRITICAL priority, automatic transaction block
- Investigation Support: AI Agent sends voice analysis to operator
- Human Decision (t=5 min): Operator converses with AI Agent for complete analysis
- Action & Audit Trail (t=10 min): Permanent block confirmed, SAR automatically generated
Outcome:
Fraudulent transaction blocked in real-time. €847,250 saved from potential laundering. Investigation time: 10 minutes vs. 45-60 minutes (traditional method).
6.2 Use Case 2: Smurfing Pattern
Scenario:
A network of 15 bank accounts makes 127 transactions in 48 hours, each ranging between €9,500 and €9,950 (just below the automatic reporting threshold of €10,000), all to the same foreign beneficiary.
Outcome:
Laundering network dismantled. €1.2M+ blocked. 15 mule accounts identified. Detection time: 2 hours vs. weeks (traditional method).
6.3 Use Case 3: Crypto Exchange Risk
Scenario:
IT startup (incorporated 6 months ago, revenue €200K/year) transfers €523,100 to a crypto exchange in Malta via SEPA Instant transfer.
Outcome:
If documentation insufficient: Transaction blocked, SAR filed. If documentation adequate: Transaction approved with enhanced monitoring. Compliance with risk-based approach maintained.
