Korean Fintech Firms Step Up Cybersecurity as Costs and Network Rules Bite

South Korean fintech companies are tightening cybersecurity controls as a widening series of attacks on financial businesses exposes the pressure facing smaller digital finance providers. Industry representatives say that the cost of compliance and restrictions on network connectivity are making it harder for some firms to deploy modern defenses, including tools that use artificial intelligence.

The Korea Fintech Industry Association brought together information technology and security officials from electronic financial service providers and member companies at One IFC in Seoul’s Yeouido district on Thursday. The meeting focused on vulnerabilities and countermeasures after hacking incidents expanded beyond conventional banks and savings banks to online lending platforms.

Participants reviewed an information technology security checklist that the Financial Services Commission had asked fintech companies to use for self-assessments. They also examined lessons from both successful and unsuccessful intrusion attempts involving electronic financial service providers.

The practical measures discussed included adding authentication requirements when systems are accessed through outside channels such as merchant networks, blocking internet protocol addresses linked to attackers, examining historical access logs, testing systems exposed to the internet for weaknesses and monitoring unusual access patterns. The association presented the work as a shift from reacting after breaches toward identifying risks before damage occurs.

Association Chairman Kim Jong-hyun said recent incidents were not confined to a single company or segment because they affect trust in financial services as a whole. He emphasized the need for a system capable of detecting risk factors early and responding proactively.

The industry’s response is unfolding while a proposed revision to the Electronic Financial Transactions Act, intended to reinforce information security obligations, has remained stalled in the National Assembly for more than 10 months. At the same time, smaller fintech businesses say the expense of obtaining Information Security Management System-Personal Information certification can be a heavy burden. Industry representatives are calling for government vouchers to help cover those costs.

Companies are also seeking changes to network separation rules that can limit smaller firms’ ability to use cloud-connected or AI-based security services. The dispute highlights a broader regulatory challenge: maintaining strict safeguards for sensitive financial data while allowing digital finance providers to adopt defensive technologies that evolve as quickly as the attacks they are designed to stop.

For Korea’s fintech sector, the immediate priority is operational resilience. The longer-term test will be whether lawmakers and regulators can raise baseline security standards without leaving smaller providers unable to afford certification or access advanced protection tools.
