KYC/AML for cross-border PSPs - spotting the red flags effectively

Hey everyone,

I'm curious to hear from those operating Payment Service Providers (PSPs), especially those dealing with cross-border transactions in multiple jurisdictions. We're constantly refining our KYC/AML protocols, and while we have a solid framework, the sheer volume and diversity of transactions can make spotting genuine red flags a real challenge. It feels like a constant game of whack-a-mole sometimes.

Specifically, what are some of the less obvious, but most effective, red flags you've integrated into your automated monitoring systems or that your teams have found particularly useful in manual reviews? Beyond the standard IP geo-location anomalies or mismatched beneficiary names, have you identified any behavioral patterns or data points that, when combined, are strong indicators of potential issues? We're always looking to improve our signal-to-noise ratio without unnecessarily impacting legitimate users, which is the tightrope walk for everyone in this space. Any insights on navigating different regulatory expectations across regions would also be much appreciated.
