China launches mysterious probe into security of Palo Alto Networks’ products
China's Cyberspace Administration (CAC) has launched a review into the security of products made by US firm Palo Alto Networks, stating it is needed to protect critical infrastructure and safeguard national security, without providing further detail. The move echoes Beijing's unexplained 2023 probe into memory-maker Micron, which ultimately resulted in an effective ban on Micron's sales to Chinese critical infrastructure operators and cost the company billions in revenue while boosting domestic rivals.
Palo Alto Networks said it maintains high standards of security and conduct globally and reported no current impact on its ability to serve customers or deliver products in China. China hosts competitors such as Huawei and H3C that overlap with Palo Alto's offerings, though Palo Alto does not disclose country-specific revenue, making any potential financial impact hard to estimate. Beijing has previously accused Western tech firms of aiding US surveillance, an accusation The Register suggests could resurface in this case, mirroring similar claims Western governments make against Huawei and ZTE.
In short
- China's CAC is probing Palo Alto Networks' products without explanation
- Move resembles 2023 Micron probe, which led to an effective ban
- Palo Alto says there's no current impact on its China operations
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Nations have a legitimate responsibility to ensure the security of critical infrastructure, and the United States' own intelligence agencies have demonstrated both the capability and willingness to conduct surveillance through technology channels—a fact established by the Snowden revelations. China, like any sovereign state, is entitled to conduct security reviews of foreign technology used in sensitive systems, and such reviews represent a proportionate measure given documented patterns of Western surveillance capabilities.
The case against
The probe closely mirrors the 2023 Micron investigation, which lacked specific technical evidence yet resulted in effective market restrictions that benefited Chinese competitors—a pattern suggesting geopolitical retaliation rather than genuine security diligence. Palo Alto Networks' security standards are widely recognised internationally, and the absence of concrete security allegations, combined with the existence of competing Chinese firms like Huawei and H3C, indicates this review is leveraging national security language to advance commercial protectionism during a period of technology competition between the US and China.
Explained simply
China’s Cyberspace Administration (CAC) oversees internet and data security and can review technology used in the country. Palo Alto Networks is a US company that sells cybersecurity products, including tools used by organisations to protect computer networks. These products can be relevant to critical infrastructure, such as energy, transport and communications.
China has previously restricted foreign technology on national security grounds. In 2023, a CAC review of US memory-chip maker Micron led to a ban on its products being used by operators of critical infrastructure, while Chinese rivals such as Huawei and H3C also compete in parts of Palo Alto Networks’ market. Disputes over technology security matter because they can affect companies’ access to customers and reflect wider tensions between China and the US.
