Global Signal Exchange – Sharing Cross-Sector Data Worldwide | Global Anti-Scam Summit London 2025

Date of Event: 26–27 March 2025

Event: Global Anti-Scam Summit London 2025

The Global Signal Exchange (GSE) session at the Global Anti-Scam Summit London 2025 showcased the powerful potential of global data collaboration in disrupting scam networks. With participation from major tech platforms, banking associations, law enforcement, and government representatives, this workshop demonstrated how sharing signals across sectors can significantly reduce coordination barriers and accelerate fraud prevention.

André Naumann of Google opened with a deep dive into the company’s support for the GSE, highlighting how the initiative streamlines internal processes, shrinks signal acquisition time, and enhances multi-sector intelligence sharing. He also shared details of a successful bilateral signal-sharing pilot between Google and Meta, where shared scam signals resulted in rapid enforcement actions.

Emily Taylor of DNS Research Federation myth-busted the notion that privacy laws obstruct fraud prevention. Instead, she emphasised how privacy and data sharing can co-exist within legal frameworks, with appropriate controls and clear governance.

Lucien Taylor followed with a technical walkthrough of the GSE’s capabilities, including real-time threat ingestion, league tables, and feedback mechanisms. He stressed the importance of data quality, velocity, and shared intelligence in stopping scams faster and more effectively.

The panel discussion brought in perspectives from Meta, Spamhaus, the UK Home Office, the American Bankers Association, 5OH Consulting, and others. Speakers underscored the need for industry-wide participation, creative use cases, and brave leadership to tackle cross-border fraud threats. The workshop ended with a call to action: “It takes a network to defeat a network.”
