In a rapidly evolving digital payments landscape, a forward-thinking fintech company needed to
enhance the security of its cloud-based payment gateway. Facing rising compliance demands and the
growing sophistication of cyber threats, the client turned to Ancrew Global to reimagine their
infrastructure on AWS. The objective: create a security-first environment capable of detecting,
preventing, and responding to threats - all while maintaining agility and customer trust.
The Challenge
The client is operating and managing multiple financial transactions, hence client required:
- A secure migration to AWS that met PCI DSS and other regulatory requirements
- Complete visibility into security threats and anomalies
- A secure and scalable integration with SaaS applications and legacy on-premises systems,
- A modern DevSecOps pipeline to catch vulnerabilities early and halt risky deployments
Traditional security practices weren’t enough. They needed a solution that merged cloud-native
innovation with enterprise-grade controls.
Ancrew Global’s Strategic Response
Ancrew Global designed a multi-layered, defense-in-depth architecture tailored for high-compliance
environments. The solution emphasized zero trust, centralized governance, and automation across
the lifecycle of the application.
Key Innovations Delivered:
- Multi-Account Governance with AWS Control Tower – Established a robust landing zone, grouping environments into Organizational Units (OUs) for isolation and better control.
- Secure Connectivity Across Ecosystems – Implemented secure, scalable, and fault-tolerant network architecture using AWS Transit Gateway, AWS PrivateLink, and Site-to-Site VPNs to enable encrypted communication between Amazon VPCs, SaaS applications, and on-premises infrastructure.
- Advanced Threat Detection and Prevention –
- Deployed AWS Network Firewall in a dedicated inspection layer
- Integrated AWS Shield, WAF and other AWS services to identify DDoS and we attacks
- Used GuardDuty, Inspector, and Macie for intelligent threat detection, vulnerability scanning, and sensitive data monitoring

- DevSecOps at the Core – Security was embedded into every phase of the software development lifecycle:
- Trivy for image vulnerability scans
- Falco for runtime anomaly detection
- Anchore for compliance checks
- Policies enforced via OPA Gatekeeper within Kubernetes clusters
- Adopted Istio for secure service-to-service communication with granular policy control
