2. The playbook
for modern fraud defense*

Fraudsters aren’t operating alone—they’re using AI, automation, and stolen credentials. Yet many fraud teams are still relying on siloed systems and rule-based tools that only catch a fraction of what’s happening. In Plaid’s new whitepaper with Javelin, you’ll get expert insights into:

  • Using shared intelligence to see the full picture of an attack

  • Reducing fraud and friction, without compromising either

Learn how top teams are shifting from fragmented defenses to connected, real-time strategies.
