About the Company
The client provides a digital banking platform to banks and credit unions, powering the online and mobile banking their customers use every day. Sitting in the path of regulated financial activity, it carries the security, privacy, and audit obligations that come with running services on behalf of regulated institutions.
The Challenge
The company was moving off its own data centers and onto AWS, and wanted that move to set the right pattern for everything built afterward. Several teams would be working in the cloud at once, which made a clear account structure and consistent guardrails more pressing than any single workload. Auditors and the institutions it serves expected centralized logging, demonstrable controls, and evidence that policies were enforced rather than merely written down, all while the existing data-center systems kept running and connecting back to AWS throughout the transition.
The Solution
NileForge started with a short discovery phase to map the existing estate, the regulatory requirements in scope, and how the company's teams actually wanted to work, then turned that into a target account structure and migration plan. The foundation was built on AWS Control Tower, which establishes the multi-account environment, the organizational units, and the dedicated management, log archive, and audit accounts a governed setup depends on. To keep everything reproducible, account provisioning and customization were handled as code through Account Factory for Terraform, with preventive guardrails enforced as service control policies and detective controls expressed as AWS Config rules.
Security and compliance were the center of gravity rather than an afterthought. AWS CloudTrail was configured as an organization trail delivering to the central log archive account, AWS Config conformance packs were mapped to the controls the business had to satisfy, and AWS Security Hub aggregated findings against recognized standards including the CIS AWS Foundations Benchmark and PCI DSS. Amazon GuardDuty was enabled across every account for threat detection, Amazon Macie was put to work identifying sensitive data in Amazon S3, and AWS Key Management Service gave the company centralized control over encryption keys.
The network was designed for private, controlled connectivity. AWS Transit Gateway forms the hub linking the company's VPCs and data centers, with an AWS Direct Connect link for steady private bandwidth and AWS Site-to-Site VPN as an encrypted backup path. Egress is centralized and inspected with AWS Network Firewall, hybrid name resolution runs through Route 53 Resolver, and interface VPC endpoints keep traffic to AWS services off the public internet. Public-facing applications sit behind Amazon CloudFront and AWS WAF. Existing servers and databases were moved using AWS Application Migration Service and AWS Database Migration Service, and access across the environment is governed through AWS IAM Identity Center federated to the company's identity provider.
The Results
- A governed, multi-account AWS environment delivered as the foundation for migration and growth
- Guardrails enforced in code, so policies are applied consistently rather than left to each team
- Centralized logging, threat detection, and standards-based findings that hold up to audit
- Private, inspected connectivity between AWS and the company's data centers throughout the move
- Reusable Terraform building blocks that make each new account quick and consistent to stand up
Build on a foundation you can prove.
