China’s regulators announced a new cybersecurity directive on January 14 2026 that bars domestic firms from using security software from three U.S. vendors—Fortinet, Broadcom (through its VMware subsidiary), and Palo Alto Networks. The move follows amendments to China’s Cybersecurity Law that took effect on January 1, 2026, and reflects the government’s broader push to replace foreign technology with domestic alternatives amid escalating U.S.–China tensions.
The ban is framed as a national‑security measure: Chinese authorities fear that the software could collect and transmit sensitive data abroad. The directive specifically targets firewalls, SD‑WAN, and Secure Access Service Edge (SASE) solutions, the core product lines that Fortinet and Palo Alto Networks offer in China. Broadcom’s VMware unit, which supplies virtualization and cloud‑security products, is also included.
Fortinet’s exposure to the Chinese market is modest—estimates place China‑derived revenue at 1–2% of its total sales. Palo Alto Networks reports a similar figure, with the Asia‑Pacific region accounting for roughly 12–13% of its revenue, of which China represents a small fraction. In contrast, Broadcom’s revenue mix shows a substantial 36% contribution from China, making the ban a more significant headwind for that company. Even for the smaller players, the loss of even a single‑digit percentage of revenue can strain margins and slow growth in an already competitive sector.
The regulatory action forces each vendor to reassess its China strategy. Fortinet and Palo Alto Networks will need to accelerate the development of domestic‑compliant products or seek alternative distribution channels, while Broadcom may have to pivot its VMware portfolio toward markets outside China. All three companies will also face increased compliance costs and potential supply‑chain disruptions as they navigate the new legal landscape. The ban underscores the growing risk of geopolitical friction on global technology supply chains and signals that Chinese authorities are willing to impose hard limits on foreign software that could compromise national security.
Investors have reacted with concern over the potential revenue loss and the broader implications for the cybersecurity industry’s exposure to China. Analysts note that while the immediate financial hit may be limited for Fortinet and Palo Alto Networks, Broadcom’s significant China footprint could translate into a more pronounced impact on its earnings and cash flow. The event also raises questions about the future of cross‑border technology trade and the speed at which U.S. vendors can adapt to shifting regulatory environments.
