Stop Scams UK (SSUK) is a cross-industry organization dedicated to combating fraud and protecting consumers across the United Kingdom. It brings together some of the world’s most prominent companies from financial services, technology, and telecommunications, including Barclays, Amazon, Google, BT, and Three to tackle scams through collaborative intelligence sharing. By distributing actionable fraud intelligence to its member organizations and sector partners, Stop Scams UK works to prevent scams before they reach consumers, safeguard public trust, and strengthen the UK’s collective defenses against an increasingly sophisticated fraud landscape. As the organization’s member base and data volumes grew, it required a modern, cloud-native platform capable of meeting the demands of real-time, cross-sector fraud prevention at national scale.
Stop Scams UK’s existing operations were heavily dependent on manual processes and email-driven communications. As SSUK expanded its member network and increased fraud data volumes, the limitations of this approach became critical operational risks.
Scalability was the most pressing concern. Manual data handling did not support efficient scaling, meaning that as SSUK brought more member organizations and processed greater volumes of fraud signals, the system would buckle under load. Efficiency suffered equally. Email-based workflows introduced delays and human error into every stage of data processing, from initial ingestion through to distribution to partners. These delays created dangerous gaps between when fraud data was received and when it could be acted upon, gaps that sophisticated fraudsters exploit. Without automated validation, data integrity was also at risk: errors in fraud intelligence could either flood partners with false signals or, worse, allow genuine fraud patterns to go undetected.
Finally, the existing system user interface and experience were not designed for the complex, high-stakes workflows required by fraud analysts and member organizations. Poor usability increased the cognitive load on operators, raised the likelihood of user error, and slowed down the response cycles that Stop Scams UK’s mission depended on. Without intervention, these compounding challenges, manual bottlenecks, scalability constraints, and poor usability, posed a direct threat to SSUK’s ability to scale its impact and maintain the trust of its high-profile member network.
10Pearls partnered with Stop Scams UK to design and deliver a fully automated, secure, and scalable fraud intelligence platform built entirely on AWS. The architecture was deployed across multiple AWS accounts to provide strong environment isolation, fine-grained access control, and independent scaling of each functional layer, Portal, Ingestion, and Distribution. At the core of the solution:
10Pearls replaced Stop Scams UK’s manual, email-driven workflows with a fully automated data pipeline built on AWS-native services.
The automated pipeline eliminated the manual handoffs that had previously delayed fraud intelligence delivery.
Handling sensitive fraud intelligence on behalf of banks, telecoms, and technology partners required the highest standards of security, access control, and compliance. 10Pearls embedded security deeply into every layer of the architecture.
The multi-account architecture gave each functional tier its own security boundary, IAM policies, and resource controls.
Effective fraud prevention at scale requires not only clean, reliable data storage but also the ability to share intelligence rapidly and securely with a network of external partners.
Amazon API Gateway transformed Stop Scams UK from a manual intelligence distributor into a real-time fraud data network.
With member organizations across the UK depending on the platform for time-sensitive fraud intelligence, consistent performance and high availability were non-negotiable.
By combining CloudFront, ALB, and NLB, 10Pearls ensured the platform could absorb traffic without performance degradation, keeping fraud intelligence flowing when it matters most.
A platform serving regulated financial institutions requires a network foundation that is as dependable as it is secure.
Route 53’s health-check-driven failover routing gave Stop Scams UK an always-on DNS layer.
The deployment of the AWS-native platform transformed Stop Scams UK’s operational capabilities. By replacing manual, email-driven workflows with fully automated ingestion, validation, and distribution pipelines built on Amazon ECS, AWS Lambda, SQS, and SNS, SSUK eliminated the processing delays that had previously slowed fraud intelligence delivery. Fraud signals are now received, validated, and distributed to member organizations in real time, giving banks, telecoms, and technology partners the timely intelligence they need to act before consumers are harmed.
Security and compliance improved significantly across all data handling and member interactions. The multi-account AWS architecture, combined with Amazon Cognito identity management and AWS WAF protection, gave Stop Scams UK a platform that meets the stringent security requirements of its regulated financial services members. Every data access event is logged, every API call is authenticated and monitored, and every environment tier operates within its own secure boundary, providing the audit trail and access controls that member organizations require.
The platform established a scalable, future-ready infrastructure for the cross-industry fraud prevention effort. With Amazon Aurora PostgreSQL managing fraud intelligence data at scale, Amazon API Gateway enabling programmatic partner integrations with organizations like Meta and LexisNexis, and a multi-account architecture that can absorb new member organizations and data sources without re-engineering the core system, Stop Scams UK now has the technological foundation to grow its impact across the UK — and to stay ahead of an evolving fraud threat landscape.
