China’s Cybersecurity Law (CSL), first introduced in 2017 and amended with updates that took effect in 2026, remains a core part of China’s broader data and cybersecurity framework. Today, companies operating in China need to read it alongside other key rules, including the Data Security Law (DSL), the Personal Information Protection Law (PIPL), and the network data security regulations that took effect in 2025.
Within that framework, China’s Cybersecurity Classified Protection System (CCPS), often discussed in practice as part of the MLPS regime, remains one of the central compliance mechanisms. It applies to Network Operators (NO) and Critical Information Infrastructure Operators (CIIO). In practice, “Network Operators” can include a very broad range of companies in China that own, manage, or use internal networks and information systems, and not only telecom or internet service providers. In other words, the regulatory scope of the CCPS can extend to a very wide range of companies operating in China, including foreign-invested businesses that run internal networks, digital systems, business platforms, or data-processing activities in China.

The essence of the law – explained
Under this framework, network operators are required to classify their information systems and networks across five protection levels, based on the degree of harm that a cybersecurity incident could cause to individual rights and interests, social order, public interests, or national security. At the lower end of the framework are systems with limited impact, while the higher levels apply to systems whose compromise could have serious consequences for society or national security. Network operators, including CIIOs where relevant, must ensure that systems at different protection levels have corresponding security protection capabilities.
They are also expected to address security risks arising from new technologies, applications, and more complex digital environments, including cloud platforms, connected devices, and other data-intensive systems. The CCPS emphasizes the importance of security protection capability, which is, the ability to prevent, detect and recover from threats, incidents, and damage.
Practical takeaways for international companies in China
Not every company or system will go through the same formal filing, testing, or certification path. However, companies operating digital systems in China should not assume that the CCPS can be ignored. In practice, businesses are expected to assess their systems, determine the relevant protection level, implement the corresponding controls, and be ready to support filings, inspections, remediation, or other compliance steps where required. Where formal evaluation or review is required, companies should confirm the expected review cycle and local enforcement practice based on the relevant system, protection level, and regulator expectations. Failure to comply can expose a business to a range of consequences, including corrective orders, inspections, remediation demands, regulatory scrutiny, fines, and in serious cases, business disruption or suspension.

CCPS Target groups:
The regulatory scope of the CCPS extends well beyond traditional information systems. It can apply to network infrastructure, critical information systems, websites, cloud computing environments, big data platforms, connected devices, industrial control systems, mobile internet environments, and other digital operating systems used by businesses in China. In addition to classification, filing, and evaluation, the framework also supports a broader enforcement environment that may include inspections, compliance inquiries, remediation instructions, incident investigation, and other supervisory measures by the relevant authorities.
What to do now?
- Verify and document how data is collected, processed, stored, accessed, and transferred across your China operations.
- Assess which systems, platforms, or business functions may fall within the CCPS / MLPS framework and determine the likely protection level for each relevant system.
- Review cybersecurity and privacy risks across your local operations, including employee data, customer data, internal systems, connected devices, and third-party platforms.
- Implement internal monitoring, access control, incident-response, and record-keeping measures that match the sensitivity of the relevant systems.
- Update internal data handling, cybersecurity, and cross-border data transfer policies so they align with China’s current legal framework.
- Assign a specific employee to take clear responsibility for ongoing cybersecurity and data compliance, ideally someone involved in the relevant systems and able to respond to regulator inquiries, as authorities may request their name and contact details.
- Where needed, obtain local technical, legal, and compliance support to prepare for filings, assessments, inspections, or remediation requirements.
Conclusions & final remarks
The CCPS remains one of the core compliance frameworks within China’s cybersecurity regime. For international companies, the key point in 2026 is that cybersecurity compliance in China should not be viewed as a narrow IT issue. It is now part of a broader legal and operational framework that also touches data governance, privacy, cross-border data flows, and internal accountability.
The good news is that companies with mature cybersecurity, privacy, and internal control systems are usually in a stronger position to adapt. Still, compliance in China requires local review and local alignment. The legal framework has become broader, enforcement has become more structured, and businesses should make sure their China operations are assessed against current local requirements rather than relying only on global policies.
