Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Coupang has a cyber risk management framework designed to identify, assess, and manage cyber related risks. Cyber related risks are identified through self-identification, audits, assessments, and incidents. Our vulnerability scanning process uses both automated tools and penetration testing to identify vulnerabilities within our environment. We seek to identify, manage and reduce the risks and potential vulnerabilities by integrating controls and solutions into information security and technology projects based on severity and priority. The Chief Information Security Officer (“CISO”), who has extensive cybersecurity knowledge and skills gained from over 15 years of work experience at the Company and elsewhere, leads our global information security organization responsible for overseeing the Coupang information security program. The CISO regularly reviews our cyber strategy with technology leadership in order to integrate the cyber strategy across the organization. The CISO is updated on cybersecurity threats from experienced information security officers in our security organization on an ongoing basis and in conjunction with management, regularly reviews risk management measures implemented by the Company to identify and mitigate data protection and cybersecurity risks. Supporting the CISO, is the dedicated information security team, which comprises almost 200 individuals. In addition to full-time employees, external consultancy services provide us with certain information security services and specialized advice. We conduct annual assessments by certified external third-party assessors as part of our industry-recognized information security certifications, ISO 27001, 27017, 27701, and ISMS-P. We periodically have external third-party consultants conduct maturity assessments of our Information Security program. The results of these audits and assessments inform us about possible risks which are managed through our enterprise risk management process. We employ external third-party vendors to provide cyber threat intelligence when relevant information is available or as requested. We also employ systems and processes designed to oversee, identify, and reduce the potential impact of a security incident at a third-party vendor, service provider, customer or otherwise implicating the third-party technology and systems we use. We also have a program of Cyber Tabletop exercises, run periodically, with key people in our business, to further enhance our capabilities to respond and recover to a cyber incident.
