Union Bank of Nigeria has secured certification under the Payment Card Industry Data Security Standard (PCI DSS) version 4.0.1, a global standard for protecting payment card data.
The certification took effect on August 11, 2026, confirming that the bank’s systems for storing, processing and transmitting customers’ credit and debit card information meet stringent international security requirements.
PCI DSS certification is designed to reduce the risk of payment card data breaches and financial fraud while strengthening customer confidence in electronic payment systems.
The assessment covered key areas of Union Bank’s operations, including network infrastructure, card issuance, ATM and POS transactions, payment processing, reconciliation, settlement, chargebacks, dispute resolution and retail banking.
Union Bank was assessed and certified under the Service Provider category.
The certification process lasted a full year and involved quarterly assessments, with support from departmental, business and functional heads across the bank. Digital security firm Digital Encode supported the process, while the final independent audit was conducted by CyberCube, an accredited Qualified Security Assessor.
Managing Director and Chief Executive Officer of Union Bank, Yetunde B. Oni, said the certification demonstrates the bank’s commitment to protecting customer information.
“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 renewal also ensures that Union Bank maintains continuous PCI DSS certification, in line with the Central Bank of Nigeria’s requirement for banks to sustain compliance without interruption.
