Secure File Exchange Modernization with AWS Transfer Family
A federal agency partnered with One Dynamic to modernize their legacy SFTP/FTPS infrastructure using AWS Transfer Family for FedRAMP-aligned secure file exchange.
Challenge
A federal agency operated a legacy FTP server to manage secure data exchanges across departments and partner entities. The system was outdated, costly, and lacked modern compliance and security controls. The agency required a FedRAMP-aligned, scalable alternative supporting file transfers from whitelisted IP addresses only.
Solution
One Dynamic implemented a secure, cloud-native architecture using AWS Transfer Family with SFTP endpoints, IAM role-based access control with MFA, VPC interface endpoints for private traffic routing, Security Groups and NACLs for IP whitelisting, CloudTrail/CloudWatch for audit logging, Lambda and EventBridge automated triggers, Terraform IaC deployment, and PGP encryption for data at rest and in transit.
Results
60% reduction in operational overhead. Full compliance with FedRAMP and internal audit requirements. Enhanced file security through IP whitelisting, VPC isolation, and PGP encryption. Automated, scalable, and cost-effective cloud solution with zero EC2 footprint. Pay-as-you-go pricing eliminating upfront infrastructure investment.
