About Cyber ​​Kunlun

Cyber Kunlun, officially Beijing CyberKunlun Technology Co., Ltd., is a cybersecurity firm established in 2021, focusing on advanced vulnerability research and defense. The company was founded by Zheng Wenbin, a prominent figure in the white-hat hacking community, who previously served as the Chief Technology Officer of Qihoo 360. During his tenure at Qihoo 360, Zheng established the 360 Vulcan research team, known for its success in international hacking competitions. Identifying a market opportunity in proactive vulnerability management amidst growing enterprise digitization, he left Qihoo 360 to create Cyber Kunlun. The executive team also includes Chief Technology Officer Xuebin Chen, another alumnus of Qihoo 360 where he was a director at the Vulnerability Research institute.

The firm specializes in providing protection against zero-day, one-day, and N-day vulnerabilities across various environments including PCs, servers, applications, and the cloud. Its core business revolves around identifying and reporting vulnerabilities in major software products from companies like Microsoft, Google, and VMware, thereby providing its clients with exclusive defense capabilities before exploits become widespread. This is demonstrated by their significant contributions to vulnerability disclosures; for instance, they were responsible for reporting 36 of Microsoft's 145 vulnerability fixes in a single month. The company’s primary product is "Kunlun·Insight," a platform offering risk defense solutions for the entire lifecycle of vulnerabilities. In addition to its core platform, Cyber Kunlun provides a suite of services such as penetration testing, security assessments, and the application of micro-patches.

Cyber Kunlun's business model is centered on selling its security products and services to large enterprises. The company serves clients across key sectors including government, energy, finance, internet, and communications. The company has secured significant financial backing to fuel its research and development and market expansion efforts. In July 2023, it raised nearly 100 million yuan (approximately $13.8M) in a Series A financing round led by Fortune Capital, with participation from existing investors like Sequoia China. This followed earlier seed and venture rounds with investors including CICC Capital, Hike Capital, and ZhenFund.
