In 2022, ING Nederland implemented HPE Guardian (by Tandem) as an Operating System (OS) platform for demonstrations of Active/Active migration scenarios supporting banking transaction workloads.

Operational scope focused on banking and transaction systems across ING Nederland and broader European transactional sites, as evidenced by the user event demonstrations rather than a formal press release.
