South Korea Tightens Privacy Rules with Tougher Penalties & New Executive Accountability Under Amended PIPA

Key Takeaways

• Punitive Penalties for Repeat Breaches: The amended Personal Information Protection Act allows South Korea’s privacy regulator to impose penalties of up to 10 percent of a company’s annual turnover in cases involving repeated or serious data breaches, significantly increasing the potential financial impact for organizations that fail to safeguard personal data.
• Earlier Notification of Privacy Risks: Organizations will be required to notify individuals when they become aware of potential data breach incidents, expanding the existing framework that previously focused primarily on confirmed breaches.
• Expanded Incident Reporting Requirements: Incidents involving the forgery, alteration, or damage of personal information, including ransomware-related events, are now explicitly included within the scope of breach notification and reporting obligations.
• Stronger Executive Accountability: The amended law clarifies that CEOs are responsible for overseeing personal information processing, while Chief Privacy Officers must manage dedicated privacy budgets and personnel and report privacy protection matters to senior leadership and boards.
• Mandatory ISMS-P Certification: Certain organizations in both the public and private sectors will be required to obtain Information Security and Personal Information Management System (ISMS-P) certification, with the requirement taking effect in July 2027.

Deep Dive

South Korea is set to strengthen its privacy enforcement regime after lawmakers approved amendments to the country’s Personal Information Protection Act (PIPA) that introduce tougher penalties for repeat data breaches, expand the responsibilities of corporate leadership, and require certain organizations to adopt formal security and privacy certification frameworks.

The Personal Information Protection Commission (PIPC) said the revised law will be promulgated on March 10, 2026, following its approval by the National Assembly earlier this year and subsequent approval by the Cabinet on March 3. Most provisions will take effect on September 11, 2026, while a new certification requirement tied to privacy and information security management systems will come into force in July 2027.

The reforms arrive at a time when large-scale data breaches have heightened public concern over how organizations manage personal information. South Korea’s privacy regulator said the changes are designed to strengthen deterrence against negligent handling of personal data while pushing companies and public institutions to invest more heavily in prevention and governance.

Tougher Penalties Aimed at Repeat Breaches

One of the most consequential changes in the amended law is a new enforcement mechanism that allows regulators to impose penalties of up to 10 percent of a company’s annual turnover when data breaches are repeated or particularly serious.

Until now, penalties for violations were capped at 3 percent of annual turnover, a level authorities suggested did not always provide sufficient deterrence.

The amendment also introduces a system intended to reward organizations that invest in stronger privacy protection. Regulators will have the ability to reduce sanctions where companies can demonstrate meaningful investments in privacy safeguards, including staffing, infrastructure, and protective technologies.

However, those incentives will not apply in cases where breaches result from intentional misconduct or gross negligence, according to the PIPC.

Earlier Alerts When Privacy Incidents Emerge

The updated law also expands how organizations must notify individuals about privacy risks. Under the current framework, companies are required to notify affected individuals once a data breach has been confirmed. The revised PIPA introduces a new obligation to notify individuals when organizations become aware of a potential breach, allowing people to respond earlier to emerging risks.

The amendment also broadens the scope of incidents that must be reported. Events involving forgery, alteration, or damage to personal information, including cases linked to ransomware attacks, will now fall within the reporting and notification requirements.

When notifying affected individuals, organizations will also need to provide information about possible remedies, such as damage claims or dispute mediation options, helping individuals better understand what recourse may be available.

CEOs and Boards Drawn Directly into Privacy Oversight

Another notable shift in the amended law focuses on corporate accountability.

The revised PIPA makes clear that chief executive officers are responsible for managing and supervising the processing of personal information within their organizations. For companies handling personal data above certain thresholds, decisions related to appointing, replacing, or dismissing a Chief Privacy Officer (CPO) must be reviewed by the board of directors and reported to the PIPC.

At the same time, the law strengthens the operational role of CPOs. They will be required to oversee dedicated personnel and budgets for privacy protection and to report privacy-related matters directly to both the CEO and the board.

The goal, regulators said, is to ensure that privacy governance is embedded at the leadership level rather than treated solely as a technical compliance issue.

New Certification Requirement for Key Data Processors

The amendments also introduce a mandatory certification requirement under the Information Security and Personal Information Management System (ISMS-P) for organizations that have a significant impact on personal data protection in both the public and private sectors.

The certification framework is intended to strengthen baseline privacy and information security practices by requiring organizations to establish formal management systems governing how personal data is handled and protected.

Details about which entities will be subject to the requirement will be specified during the upcoming revision of PIPA’s enforcement decree.

Because organizations may need time to prepare resources and budgets, the certification mandate will take effect later than the rest of the amendments, beginning July 1, 2027.

The PIPC said it will accelerate work on updating the enforcement decree and related regulations needed to implement the amended law. At the same time, the regulator said it plans to work closely with both industry and public-sector organizations to support implementation of the new framework.
