Case Study: a large aerospace & defense company achieves scalable, audit-ready attestations with CoreStream GRC

How aerospace & defense teams rebuilt attestations for scale and accuracy with CoreStream GRC

A large aerospace & defense company faced significant challenges with its manual governance, risk, and compliance (GRC) processes. It relied on spreadsheets and email for attestations, which led to time-consuming consolidation, inconsistent data, a weak audit trail, and a lack of real-time visibility for leadership. This created an unsustainable "evidence debt," where proving compliance required a major, manual rebuild of documentation for each audit or leadership request. The company turned to vendor CoreStream and its GRC platform to automate these workflows.

CoreStream GRC implemented an automated Management Assurance solution that transformed the attestation process. The new system featured quarterly survey cycles with automated alerts, intelligent forms, and a consistent review workflow. It generated corrective actions and provided executive dashboards for real-time visibility. As a result, manual consolidation and chasing dropped sharply, leadership gained live insight into outcomes, and corrective actions were tracked to closure, creating a defensible and repeatable assurance process.
