Indonesian banks strengthen cyber defences as BI steps up coordination

Bank Indonesia is stepping up coordination with banks and payment-system providers to prepare for cyberattack threats, while Indonesian lenders say they are strengthening technology security and monitoring potential risks.

Executives from BRI, CIMB Niaga, Bank INA and Bank Oke Indonesia described their precautions to CNBC Indonesia on 10 November 2026. Their measures include layered safeguards, continuous monitoring and improvements to technology infrastructure.

BRI corporate secretary Dhanny said the bank was intensifying monitoring and strengthening measures to prevent and mitigate cyber threats. He said the work followed guidance from regulators, including Bank Indonesia and the Financial Services Authority, known as OJK.

CIMB Niaga’s director of operations, technology, analytics and AI, Rico Usthavia Frans, said its technology and cybersecurity teams were tracking global threats, reviewing risks and reinforcing preventive controls. The bank also reminded customers to remain alert to criminal schemes and misuse of banking information.

Bank INA deputy president director Yulius Purnama Junaedi said the lender was maintaining surveillance, upgrading information-technology infrastructure and mitigating risks. He also urged the public to check that information circulating on social media came from official sources.

Bank Oke Indonesia compliance director Efdinal Alamsyah said banks welcomed the regulator’s coordination. He said the industry was committed to stronger security systems, closer threat monitoring and readiness to mitigate cyber risks, with customer data, funds and service continuity among its priorities.
