What specific penalties can enterprises face for using unauthorized VPNs?

Under the Interim Regulations on the Administration of International Networking of Computer Information Networks, unauthorized use of VPNs for international networking may result in warnings, orders to cease networking, confiscation of illegal gains, and fines. In severe cases, business licenses may be revoked.

How can an enterprise determine if its VPN service is compliant?

Enterprises should verify whether the VPN service provider holds a Value-Added Telecommunications Service License (including 'Internet Virtual Private Network Business') issued by the Ministry of Industry and Information Technology. Additionally, the VPN deployment must use state-approved encryption algorithms and ensure data transmission paths comply with data localization requirements.

What is the difference between VPN and dedicated lines for cross-border data flows?

VPNs establish encrypted tunnels over public networks, offering lower costs but higher compliance risks. Dedicated lines (e.g., international private lines, SD-WAN) provide dedicated physical or logical channels, generally offering greater stability and easier regulatory compliance, but at higher costs. Enterprises should choose based on data sensitivity and business needs.

VPN Compliance in Cross-Border Data Flows: Legal Risks and Mitigation Strategies for Enterprises

7/3/2026 · 2 min

1. Background of Cross-Border Data Flows and VPN Compliance

As enterprises expand globally, they frequently rely on Virtual Private Networks (VPNs) to facilitate cross-border data transfers. However, with increasingly stringent regulations on data sovereignty and cybersecurity worldwide, the use of VPNs is no longer merely a technical choice but also involves complex legal compliance issues. China's Cybersecurity Law, Data Security Law, and Personal Information Protection Law all impose clear requirements on cross-border data flows. Enterprises that use VPNs in violation of these laws may face administrative penalties, civil compensation, or even criminal liability.

2. Key Legal Risks for Enterprises Using VPNs

2.1 Data Localization and Cross-Border Transfer Restrictions

Chinese law requires Critical Information Infrastructure Operators (CIIOs) and entities processing a certain volume of personal information to store domestically collected data within China. If data needs to be transferred abroad, enterprises must follow compliance pathways such as security assessments, certification, or standard contracts. Directly transferring data via VPN without approval constitutes a violation.

2.2 Risks of Using Unauthorized VPN Services

According to the Interim Regulations on the Administration of International Networking of Computer Information Networks, no organization or individual may establish or use VPNs for international networking without approval from the telecommunications authority. Using unauthorized VPN services may be deemed illegal cross-border networking, leading to warnings, fines, or even revocation of business licenses.

2.3 Cybersecurity Review and Supply Chain Risks

If an enterprise's VPN service provider has security vulnerabilities or is controlled by a foreign government, it may lead to data leakage or unauthorized access. China's Cybersecurity Review Measures stipulate that CIIOs purchasing network products and services that may affect national security must undergo a cybersecurity review.

3. Compliance Mitigation Strategies

3.1 Establish Data Classification and Outbound Assessment Mechanisms

Enterprises should first classify and grade cross-border data to identify types involving personal information, important data, or core data. For data that needs to be transferred abroad, enterprises should conduct data outbound security assessments, obtain personal information protection certification, or sign standard contracts with overseas recipients in accordance with the law.

3.2 Select Compliant VPN Services and Network Architectures

Enterprises should prioritize service providers holding a Value-Added Telecommunications Service License (VPN business) from the Ministry of Industry and Information Technology, and adopt compliant cross-border network solutions such as dedicated lines or SD-WAN. Additionally, ensure that VPN deployment complies with national cryptographic management requirements and uses approved encryption algorithms.

3.3 Enhance Internal Data Governance and Employee Training

Develop a cross-border data flow management system that clearly defines VPN usage permissions and approval processes. Conduct regular data compliance training for employees to prevent personal misuse of VPNs from leading to enterprise liability.

4. Conclusion

VPN compliance in cross-border data flows is a critical aspect of global business operations. Enterprises must build a compliance framework from legal, technical, and management perspectives to balance operational efficiency with legal risks. As regulations evolve, enterprises should continuously monitor policy changes and seek professional legal advice when necessary.
