This global financial services firm is a leader in supplying public companies with proxy and shareholder communications, annual reports, and other financial documents.

  • GDPR compliance created significant challenges for this global business’s core data processing applications which were run on a mainframe in the United States but utilized internationally.
  • No single vendor product could solve these challenges and configuring a new European mainframe did not make business sense.
  • Developing a custom solution from scratch would be expensive and time-consuming


  • Axis developed a hybrid solution integrating Delphix Masking and Virtualization with Sotero Protect© that meet the needs of the client, including
  • Automated mainframe masking, creation of virtual databases from custom self-service templates, security policy configuration, application profiling, and masking, and Sotero API integration.
  • Used the APIs to integrate these two leading data privacy products.
  • Axis’s repeatable, scalable solution allowed the client to comply with GDPR requirements without opening a new data center in Europe.
