Deploying a Secure, PCI-DSS Compliant Cloud Operations Baseline for a Leading European Fintech
Industry
Financial Services
Challenge
As a rapidly growing European fintech, the customer required a resilient, scalable cloud environment capable of supporting surging transaction volumes while strictly adhering to PCI-DSS compliance standards. Without robust preventative governance guardrails and a secure operational baseline, the company risked failing regulatory audits, compromising merchant trust, and exposing sensitive financial data to potential security breaches as they expanded internationally.
Results
Cloud Office delivered a highly governed, PCI-DSS compliant AWS foundation powered by serverless container operations and end-to-end Infrastructure as Code (IaC) automation. This modern cloud operational baseline reduced ongoing maintenance overhead, simplified regulatory compliance, and enabled the customer to rapidly deploy new payment solutions while confidently scaling high-volume transaction processing across Europe.
Key Product
AWS, Terraform
About your Customer
The customer is a Payment Card Acquirer providing secure, tailored payment solutions for merchants across Europe and the UK. The company holds Principal Membership licences with Mastercard and Visa and is an authorised Payment Institution in both the EU and the UK. In 2026, the company was recognized among Europe’s Fastest Growing Companies by the Financial Times.The Challenge
The customer required a cloud environment capable of supporting increasing transaction volumes while meeting the strict security and compliance requirements of the payments industry. Future growth had to be supported without compromising operational resilience, governance, or merchant trust. Given the nature of their business, the operational baseline had to be incredibly resilient, scalable, and built strictly to PCI-DSS compliance standards. Any architectural missteps or lack of preventative governance guardrails would not only fail compliance audits but could lead to catastrophic data breaches and permanent loss of merchant trust.
The Solution
Rather than simply deploying infrastructure, Cloud Office worked closely with the customer to design a cloud operating model that would support both current operations and future growth. Every architectural decision was made with scalability, security, and operational efficiency in mind, enabling the company to focus on delivering payment solutions while relying on an automated, highly governed cloud foundation.
We laid the groundwork by deploying a multi-account AWS Landing Zone via AWS Control Tower, enforcing robust organizational Service Control Policies (SCPs), centralized logging, and strict environment separation to satisfy financial auditing requirements.
To ensure operational agility and minimize maintenance overhead, we designed their payment processing architecture around Amazon Elastic Container Service (Amazon ECS) running on AWS Fargate. This serverless compute model allowed the platform to handle high-volume transaction spikes without requiring the customer's team to manually provision or operate virtual machines.
The complete solution design—including the advanced networking, security controls, and the containerized application layer—was entirely automated and provisioned using Terraform to ensure flawless, repeatable deployments.
The Results
Cloud Office successfully delivered a highly governed, scalable cloud foundation aligned with the customer’s PCI-DSS requirements. By leveraging Infrastructure as Code (IaC), serverless container operations, and automated governance, the company established a resilient, low-maintenance cloud environment capable of securely processing high-volume financial transactions across Europe.
The new AWS foundation provides a secure, scalable platform that supports the customer’s continued growth while reducing operational overhead through automation. With governance embedded from day one and infrastructure deployed as code, the company can introduce new services faster, maintain compliance more efficiently, and confidently scale its payment processing operations as transaction volumes continue to grow.
