By Adebola Muili

Union Bank of Nigeria has attained certification under the Payment Card Industry Data Security Standard (PCI DSS) version 4.0.1, reinforcing its commitment to safeguarding customers’ payment card data and strengthening protection against financial fraud.

The certification took effect on August 11, 2026, and represents the bank’s continued compliance with the global standard governing the secure storage, processing and transmission of payment card account data.

According to the bank, the certification covers critical areas of its operations, including network infrastructure, card issuance, Automated Teller Machine (ATM) and Point-of-Sale (POS) transaction acquiring and payment processing, reconciliation, settlement, chargeback, dispute resolution and retail banking.

Union Bank was assessed and certified in the Service Provider category following a year-long compliance exercise involving quarterly assessments and the participation of departmental, business and functional heads across the bank.

The assessment was conducted in partnership with Digital Encode, while the final independent audit was carried out by CyberCube, an accredited Qualified Security Assessor.

Commenting on the certification, the Managing Director and Chief Executive Officer of Union Bank, Yetunde B. Oni, said the protection of customers’ information remained central to the bank’s operations.

She said, “The security of our customers’ information is central to everything we do at Union Bank. This certification reaffirms that our payment systems and processes meet a rigorous global standard, and it reflects the discipline of colleagues across the Bank who work every day to keep customer data safe.”

The bank said the renewed certification also ensures that it maintains unbroken PCI DSS compliance, in line with the Central Bank of Nigeria’s requirement that banks sustain continuous compliance without any gap.
