Kakao Platform Service supports businesses and individuals in developing applications and operating them in the global market by integrating with various Kakao services. Kakao prioritizes infrastructure management, scalability, and security, enabling members to focus on development and business logic. Kakao applies the highest level of security standards to thoroughly manage platform security, ensuring that members can operate in a safer environment. From physical infrastructure to the application layer, Kakao implements security controls at every stage to protect the member's service from diverse threats. Our platform and security teams proactively respond to vulnerabilities and provide timely security updates, allowing members to run their applications safely without interruptions or additional actions.
Trust is a core value at Kakao. Kakao places the highest priority on the protection of user's personal information and trust. Every decision is made with care and caution, and all employees share the responsibility of maintaining this commitment.
Kakao operates both in-house and external data centers securely. All data centers are located in South Korea.
Kakao has established and continuously strengthens its information security management system. Kakao has obtained the ISO/IEC 27001 (Information Security Management System) certification, as well as the ISO/IEC 27701 certification for personal information protection. Additionally, Kakao has acquired the highest-level domestic information security certification, ISMS-P, for services including Kakao Talk and Kakao Developers, thereby establishing a globally standardized secure environment.
Based on experience in operating large-scale services and managing physical infrastructure, Kakao rigorously manages all infrastructure operations. Server room access is strictly controlled and permitted only upon approval, with thorough surveillance using CCTV and access control systems. Visitors must request access in advance and receive approval to enter.
Automatic fire detection and suppression systems are installed to minimize risks. Fire detection sensors are deployed in all data center spaces including mechanical, electrical, cooling, and generator rooms. These areas are also protected by systems such as wet pipe and sprinkler systems.
Power systems in data centers are designed for full redundancy and maintenance without affecting 24/7 operations. Uninterruptible Power Supplies (UPS) provide backup power in case of electrical issues to ensure continued operation of critical systems. Generators are used to supply backup power to the entire facility.
Temperature control is essential to prevent server overheating and ensure consistent operation of hardware. Data centers are monitored and adjusted to maintain optimal air conditions. Monitoring systems and personnel regularly check temperature and humidity levels.
Data center staff monitor mechanical, electrical, and support systems to promptly identify issues. Preventive maintenance is conducted to ensure the continuous operation of equipment.
Firewalls strengthen security by restricting access between internal systems and external networks. By default, all access is blocked, and only explicitly permitted ports and protocols are allowed based on business needs. Systems are assigned to security groups by function, allowing only essential access and minimizing risks.
The Intrusion Detection System (IDS) monitors internal and external network traffic in real time, detecting abnormal access patterns. It utilizes pattern matching and detection technologies to identify threats, with real-time log monitoring and automated analysis systems for fast response.
Kakao operates security systems capable of handling various DDoS attacks, including TCP/UDP-based attacks and connection request floods. Kakao continuously analyzes attack patterns and apply appropriate defense logic to minimize service impact.
The scope of end users using applications on Kakao Platform Services is logically limited to within each respective application. Therefore, data is valid only within its own application and stored separately, preventing unauthorized access between applications.
Kakao maintains consistent system configurations based on modern stable standards and manage them continuously. Security updates are promptly applied after adequate validation. Legacy systems are either retired or replaced with up-to-date versions as needed.
Kakao enforces strict access control policies for operating systems and systems, allowing only authorized personnel to access them. All access goes through secure authentication processes. Direct external network access is not allowed by default, and all access logs are rigorously monitored and tracked to prevent threats in advance.
Kakao operates a comprehensive vulnerability management process to protect platform services from security threats. Vulnerabilities are identified and managed continuously across prevention, detection, and response phases. A dedicated security team monitors threats around the clock. Kakao also runs a bug bounty program and collaborates closely with external security researchers. Identified vulnerabilities are prioritized by risk and impact, and appropriate actions are taken.
Kakao's security team regularly conducts internal penetration testing and vulnerability assessments. Third-party assessments are conducted by independent and trusted security firms through separate contracts or agreements.
All application-related data is backed up daily and redundantly stored. In case of database failures, services can run using real-time backups. Lost data can be restored from the latest snapshot.
In the event of a failure, Kakao's platform services automatically perform dynamic recovery of member's applications and databases through redundant configurations.
Kakao Platform Services are designed for reliability and scalability. The system is architected to minimize disruptions during recovery. Services are configured redundantly to prevent single points of failure, and multiple data centers are used for restoration. Kakao thoroughly reviews platform issues to identify root causes and assess the impact on services, and continuously improves the platform and its processes.
Kakao publishes a clear privacy policy specifying what data is collected and how it is used. Kakao is committed to protecting user information and ensuring transparency.
Kakao takes several layered measures to protect users' personal information and the data stored within the platform. As part of the built-in defenses of the Kakao Platform Service, these measures include authentication, access control, encryption of data in transit, HTTPS support for members' applications, and encryption of stored data. For more details, refer to Privacy Policy. For more information about Kakao's personal data protection practices, refer to Kakao Privacy.
Kakao employees do not access or interact with user data or applications during routine operations. Access is granted only upon user request or legal obligation, and such access is strictly controlled and authenticated.
If you discover a vulnerability during service use, you can report it via the Kakao Bug Bounty website or DevTalk.
Applications must use secure communication methods like HTTPS to protect sensitive data in transit. This ensures encrypted channels prevent data theft or tampering. HTTPS guarantees confidentiality, integrity, and authentication.
Applications must encrypt all sensitive data stored in file systems or databases. This protects the data from unauthorized access and ensures confidentiality and integrity.
Use strong passwords for account and certificate keys to prevent unauthorized access. Store keys securely to avoid exposure. If a key is lost or compromised, it should be replaced immediately. Instead of sharing developer accounts, use the team invitation feature provided by Kakao Platform Services.
When developing applications on Kakao Platform Services, you may choose to use third-party services such as Amazon S3 or email providers. In such cases, always follow security best practices for handling data shared with these providers, just as you would when working with Kakao.
