Qi An Xin is one of the two largest security companies in China and exists because of a split from the other one. It grew out of the enterprise arm of Qihoo 360, separated from it in 2019 after a disagreement between the two sides, and listed on the Shanghai Stock Exchange's STAR Market under the code 688561. Its business is enterprise and government rather than consumer, and it supplied security for national events including the Beijing 2022 Winter Olympics. Its products are known in China by name rather than by category. Tianqing (天擎) is its endpoint security management system, Tianyan (天眼) its threat detection and analysis platform, and its range extends to a next-generation firewall, zero-trust network access, a hardened browser, a security operations platform (NGSOC) and QAX-GPT, a large-language-model assistant for security analysts. Its market is domestic, and its products are not submitted to the Western public test cycles this index draws on. An empty result column for a Chinese enterprise vendor should be read as an absence of evidence, not as evidence of absence. Vendor page →
