GSS and Storm Reply Launch AI 'Cloud Guardian' to Revolutionize Sanctions Screening Infrastructure

Global Screening Services (GSS) has partnered with cloud engineering firm Storm Reply to launch Cloud Guardian, an AI-powered tool designed to accelerate infrastructure updates for its sanctions screening platform. For fintech professionals, this represents a significant shift in RegTech agility, reducing the time required to implement critical system changes while maintaining the rigorous human oversight required by financial regulators.

What was announced

The collaboration introduces "Cloud Guardian," a cloud-native solution built on Amazon Web Services (AWS) that automates the analysis of proposed infrastructure changes. The tool is designed to help GSS engineers distinguish between routine updates and those requiring deeper scrutiny, ensuring that final release decisions remain under human control. This capability addresses a critical bottleneck in the sanctions screening sector, where over 40 billion cross-border transactions are screened annually. Currently, nearly 99% of flagged transactions result in false positives, leading to significant operational delays and costs for financial institutions. GSS, which secured $47 million (£37 million) in Series A2 funding in 2024, aims to centralize this process to reduce such inefficiencies.

The impact on internal workflows is substantial. Preparation for complex infrastructure releases has been reduced from approximately two days to less than four hours. Furthermore, individual technical reviews that previously occupied 30 minutes of an engineer's time can now be completed in roughly three minutes. By focusing human expertise on specific issues flagged by the AI rather than manual line-by-line code reviews, GSS aims to improve service availability and respond more effectively to the FCA’s concerns regarding outdated lists and poor screening configurations. The solution integrates directly into GSS’s existing workflows, meaning the firm did not need to replace its underlying infrastructure tools or create separate review processes. Storm Reply worked alongside GSS engineers to determine which AI models could deliver reliable analysis at an acceptable operating cost.

"The challenge was to help GSS move faster without weakening the controls around a highly important financial services platform. The biggest opportunity for AI here was not to automate the final decision, but to reduce the amount of manual interpretation engineers had to do before they could make that decision."

The companies involved

Global Screening Services (GSS) is a London-based RegTech company specializing in sanctions screening technology for regulated financial institutions. The firm focuses on providing a centralized, cloud-based screening service to eliminate the redundancy of transactions being screened multiple times as they move through different jurisdictions. GSS has established itself as a major player in the compliance space, notably raising over $47 million (£37 million) in a Series A2 funding round in 2024 to scale its operations and address the high frequency of false positives in global payments. The company's platform is designed to standardize screening across the industry, moving away from the fragmented approach that currently defines cross-border compliance.

Storm Reply, the partner on this project, is a specialized cloud engineering company and an AWS Premier Consulting Partner. The firm works with organizations to build and manage cloud-native solutions, focusing on complex technical integrations and the implementation of AI within secure environments. In this partnership, Storm Reply’s engineers worked directly alongside GSS’s platform team to select appropriate AI models and test instructions that could deliver reliable analysis at a sustainable operating cost. This collaboration ensured that the technology remained manageable by GSS’s internal team, who have developed the specific knowledge required to maintain the Cloud Guardian solution independently.

What FF News has reported before

FF News has closely followed GSS’s trajectory within the RegTech sector. In early 2023, we reported on the company’s initial momentum when Sanctions screening fintech GSS raises £37m in first funding round. Since then, the firm has expanded its industry influence, as seen when RegTech innovator GSS Teams Up with Swift to Drive Frictionless Cross-Border Payments to streamline international transactions. More recently, FF News covered the firm’s research into the future of the sector in 97% of Leading Financial Institutions Believe Industry Collaboration is Essential for 2025, Finds GSS, highlighting a broad industry consensus on the need for shared standards in compliance.

What this means

This move highlights a growing trend in fintech where AI is utilized for "back-of-the-house" infrastructure rather than just customer-facing features. By applying AI to the DevOps pipeline, GSS is addressing the inherent tension between regulatory stability and the need for rapid technical evolution. The sanctions landscape is increasingly volatile; any delay in updating screening configurations creates immediate compliance risk. This announcement puts pressure on traditional compliance vendors who rely on slower, manual release cycles. The industry is moving toward a model where the speed of infrastructure deployment is as critical as the accuracy of the screening algorithms themselves.
