Enhanced the security framework for critical data exchanges between two major financial institutions. While existing standard security measures like dedicated VPN tunnels and SFTP were already in place, this project implemented an additional robust layer of protection using GPG (GNU Privacy Guard) encryption and digital signature verification. Integrating GPG, a reference Open-Source security tool, into these critical business processes was a particularly positive aspect of this initiative.

The initiative required a detailed review and modification of multiple existing data import workflows across various systems. Key implementation tasks involved integrating automated data decryption and signature validation steps directly into these workflows, ensuring verification occurred before any data was processed into the different target systems.

This significantly strengthened data confidentiality and integrity during transit and rest, and provided verifiable proof of data origin and authenticity, ensuring regulatory compliance and inter-organizational trust.
