AI-based data security company Cohesity said on Wednesday that NH NongHyup Bank has built a public cloud-based remote offsite backup system and an automated recovery verification framework, the first among South Korean commercial banks.

Cohesity said NH NongHyup Bank adopted Cohesity Alta Data Protection on Azure, meeting financial compliance requirements while cutting operating costs and strengthening data protection capabilities.

Cohesity said NH NongHyup Bank has faced operational limits with its existing on-premises, tape-based offsite backup approach as the volume of backup data has surged due to the expansion of digital financial services. It cited the need to add physical equipment, staffing burdens for management, and a lack of space at disaster recovery centers. It also said the tape-based approach was inefficient in time and cost because it required media to be physically taken out and systems to be configured manually for each recovery verification.

To address the issues, NH NongHyup Bank reviewed a shift to a public cloud structure based on a trend of easing cloud regulations in the financial sector and its experience operating public cloud for disaster recovery purposes. After confirming the feasibility of using cloud backup through a non-enforcement opinion from the Financial Supervisory Service, the bank selected Cohesity Alta Data Protection on Azure as the final solution.

After adopting the solution, NH NongHyup Bank achieved cost savings of about 2.8 billion won based on five-year total cost of ownership. Backup time fell 71 percent from the previous level, while recovery time was cut 94 percent.

Park Do-sung (박도성), an executive vice president at NH NongHyup Bank, said the bank set a new milestone in financial innovation by successfully establishing a public cloud-based backup system, the first among South Korean commercial banks. He said the bank plans to expand the application beyond the initial scope of work to all remaining business areas in the first half of 2026 to complete a more robust and sustainable digital financial protection framework.

Sang-hoon Lee (이상훈), head of Cohesity Korea, said the rising costs and delayed recovery associated with the existing tape-based offsite approach were challenges that must be overcome in an era of digital transformation in which strong cyber response and recovery capabilities are essential. He said the NH NongHyup Bank case would become a leading model showing that, based on Cohesity's security technology, financial-sector cyber resilience can be maximised in a public cloud environment while strengthening security and cutting total cost of ownership at the same time.
