China launches mysterious probe into security of Palo Alto Networks' products
China’s Cyberspace Administration announced a review of Palo Alto Networks’ products, citing the need to protect critical information infrastructure and national security. The regulator provided no further details, echoing a similar 2023 probe that targeted Micron’s products. The impact on Palo Alto’s Chinese sales remains unclear as the company has not responded publicly.
- ▪The CAC said the review is intended to ensure safe and stable operation of critical information infrastructure and to prevent cybersecurity risks.
- ▪The announcement mirrors a 2023 investigation into Micron, which resulted in a ban on its products for critical infrastructure operators in China.
- ▪Palo Alto Networks has not commented on the probe, and the company does not disclose revenue by country, making potential financial effects uncertain.
- ▪Chinese security firms such as Huawei and H3C offer competing products that could benefit if Palo Alto faces restrictions.
