1. What is "CN compliance for the Korean E3 site cluster, and which business scenarios are suitable?"

Definition and scope of application

The Korean E3 site cluster usually refers to multiple sites or disguised sites hosted in Korean data centers or cloud platforms, targeting Chinese users or reaching traffic within China, which involves CN compliance issues. Applicable scenarios include marketing sites targeting the Chinese market, landing pages, download pages, API integration, and more.

Why should we pay attention

?

Even if the servers are in South Korea, as long as the content or services are directed at Chinese users, they may trigger compliance obligations related to China's network information management, data transfer, advertising, and financial regulation. Neglecting them could result in blocking, blocking, or administrative penalties.

Key tips

The judgment is based on "actual impact on Chinese users," not just the location of the data center. If the target traffic or business volume has a clear Chinese origin, CN compliance should be incorporated into the scheme design.

2. When deploying a cluster of data centers in South Korea, what core requirements must be met for CN compliance?

Core compliance dimension

Mainly includes: 1) Content compliance (political/regulatory issues/pornography, etc.); 2) Data compliance (personal information and cross-border transfers); 3) Compliance with filing and access (ICP filing is required for hosting in mainland China); 4) Advertising and financial regulation (if related to finance, healthcare, education, etc.).

Technical and compliance checklist

- Data classification and encryption; - Clarify the basis for data export and user consent; - Use compliant third-party payment and advertising channels; - Establishing manual and automated review processes for sensitive content; - When necessary, establish a domestic backup domain or image and handle the corresponding filing.

Practical advice

If you do not wish to file in mainland China, you can choose to design compliance through a Hong Kong/overseas ID, but you still need to prepare for possible network blocking and legal risks; For high-risk industries, it is recommended to cooperate directly with mainland compliance parties.

3. What are the main risks facing Chinese regulation or being blocked, and how can they be avoided in operations?

Common risk points

Risks include: being listed as illegal or non-compliant content by the Ministry of Industry and Information Technology/Cyberspace Administration; Blocked by ISP DNS/IP; Fines due to personal information violations; Advertising or financial promotion being taken down, etc. These often stem from content, data, or third-party qualification issues.

Checklist of avoidance measures

- Content management: establishing a sensitive vocabulary database and manual review mechanism; - Data compliance: Develop cross-border data transfer assessments and obtain user consent; - Technical measures: multi-line CDN, domain name backup, backup servers; - Partners: Require local service providers to provide legal compliance certificates (business license, ICP/ICP number, police filing screenshot, etc.).

Operational Recommendations

Regular compliance self-inspections, retention of logs and audit records, and collaboration with legal advisors enable rapid responses and offline removal of issues when complaints or agency notifications arise, reducing penalties.

4. What qualifications and capabilities should be prioritized when choosing a local service provider (Mainland/Hong Kong)?

Key points of

qualifications and service capability

Priority: 1) Complete qualifications (business license, ICP, public security filing, relevant industry licenses); 2) Compliance experience (having provided compliance solutions to similar clients); 3) Technical capabilities (CDN, WAF, DDoS protection, backup, and disaster recovery); 4) Response and SLA (24/7 support, legal/compliance assistance).

Checklist

- Request to review real cases and client lists (confidential, NDA can be signed); - Request copies of compliance proof materials; - Testing its emergency response procedures (simulating offline/ban response times); - Confirm the data center and network path, and whether there is proximity optimization to the target market.

Business and contract attention

Beyond pricing, pay attention to contract risks such as risk sharing, technical support response times, settlement and refund clauses, and whether legal assistance or administrative communication support can be provided.

5. What key contract terms and best practices are there in contract and operations when signing contracts with local service providers?

Key contract terms

Must include: scope of services and SLAs, allocation of compliance responsibilities, data processing and export terms, change and offline removal procedures, confidentiality and penalties, dispute resolution and jurisdiction clauses, termination and renewal terms.

Operational best practices

- Agree on routine compliance inspection cycles and reports; - Establish emergency incident notification mechanisms and traceability of responsibilities; - Require service providers to keep access logs and archive them according to regulatory retention periods; - Clarify third-party supply chain review responsibilities (such as CDN, payment, SMS).

Practical advice

Conduct legal and security due diligence (KYC/security testing) before signing, and clearly specify penalties and remedial steps in the contract; Regularly review contracts and compliance status, maintaining open communication channels with the local legal team.
