Analysis indicates that two Chinese cybersecurity firms are drawing attention from institutional investors amid cyber warfare risks and Beijing's technology self-reliance policy. QiAnXin Technology, which safeguarded the Beijing Winter Olympics and Chinese government infrastructure, benefits from the Xinchuang policy mandating government agencies to switch entirely to domestic software and hardware. It has also shifted its business model toward subscription-based cloud security services, generating recurring revenue resilient to economic cycles. Meanwhile, QuantumCTek is the first Chinese company to go public with quantum communication technology and quantum key distribution. It has built the world's longest ground-based quantum communication trunk line between Beijing and Shanghai and holds a technological monopoly that the government deems too critical to fail. The more the West pressures China on technology, the more subsidies and domestic orders will flow into this company.
