Collective Intelligence Is the Future of Fraud Prevention

How Legatus Helps You Share, Defend, and prepare for PSR/PSD3

The European Union is about to redefine how financial institutions fight fraud.
With the introduction of the Payment Services Regulation (PSR) and PSD3, banks, payment providers, and fintechs will no longer be able to operate in isolation. Instead, collaboration will become a regulatory obligation — and a strategic advantage.

At the heart of this shift is a simple idea:
No single institution can see the full picture — but together, we can.
To meet this challenge, we’re proud to introduce the new Fraud Intelligence & Compliance Module in Legatus.

The Challenge: Sharing and Using Fraud Data Responsibly

PSR and PSD3 will require payment service providers (PSPs) to:

  • Share information about confirmed fraud (e.g., mule accounts, scam-linked IBANs)
  • Ingest and use data from other institutions to improve their own fraud detection
  • Do all of this in a way that is compliant with GDPR, auditable, and explainable

The challenge isn’t just technical — it’s legal, operational, and architectural.

The Solution: Legatus Fraud Intelligence & Compliance Module

The new module will equip financial institutions with a modular and compliant toolkit to:
  • With full control, via policy-based automation or manual approval
  • Mapped to national or international APIs
  • With audit logs, consent flags, and compliance readiness
  • From batch files, APIs, or real-time streams 
  • Tagged by source and weighted by institution-defined trust levels
  • Profiled into Legatus’ master data engine and used in real-time scoring
  • GDPR-aligned pseudonymization and retention control
  • Built-in audit trail for every shared or consumed data point
  • Real-time dashboards to monitor sharing outcomes and external signal impact

Real Use CasesWith Legatus, you gain a fully integrated solution that helps you not only comply — but lead.   

What does it look like for your team:
  • A scammer is detected using multiple banks — Legatus alerts your team when a flagged IBAN appears in your system
  • A fraudulent merchant is shared via your national fraud hub — Legatus automatically weights inbound transactions from that source
  • Your fraud team confirms a new mule account — with one click, it’s shared to the ecosystem, safely and legally

Why This Matters?

This is not just about checking a box. Fraud data sharing is becoming a pillar of EU payment security strategy — and PSPs who can’t keep up will face:

  • Increased regulatory pressure
  • Legal exposure for inaction
  • Higher fraud losses due to isolated risk models

With Legatus, you gain a fully integrated solution that helps you not only comply — but lead.

Are You Ready for PSR/PSD3?

PSR and PSD3 will come into full effect in stages between 2026 and 2028. The time to act is now.

Legatus is ready — and with our new Fraud Intelligence Module, you can be too.
