What Chaitin Tech does

Chaitin Tech (长亭科技) is a Beijing-based, privately held cybersecurity vendor founded in 2014 that builds an AI-powered security platform spanning web application firewall (SafeLine/雷池), cloud workload protection (CloudWalker), vulnerability management (X-Ray, Cloud Atlas, Insight), network threat detection and deception (T-ANSWER, D-Sensor), breach and attack simulation (Alioth), and security analytics with a proprietary security-tuned large language model (ChaitinAI, COSMOS). The platform is distinguished by semantic traffic analysis — claimed to deliver 99.9956% attack detection — rather than signature-only inspection, and by an attacker-perspective design ethos reflected in the founders' sustained Top-3 finishes in China's national offensive/defensive security exercises.

The company serves more than 5,000 enterprise and government clients across finance (China Guangfa Bank, Shanghai and Shenzhen Stock Exchanges), telecom (China Mobile), central state-owned enterprises (State Grid), internet platforms (Huawei, Bilibili, DiDi, iQiyi, Xiaohongshu, Vivo), logistics (SF Express), and education (Tsinghua, Nankai University). SafeLine is the leading open-source WAF on GitHub with over 20,000 stars, and Chaitin ranked #1 in IDC's China AI-Enabled WAF Hardware Market Share 2025 report with 14.4% share and 41.6% annual revenue growth on that line.

Chaitin generates revenue through a mix of subscription-based enterprise products (hardware and software deployment models), managed security services (MSS), professional consulting (penetration testing, code audits, red/blue team construction), and training/CTF services. Distribution runs through direct enterprise field sales, the WanZhong channel partner platform, and open-source community-led adoption for SafeLine. The company has raised approximately $232M cumulatively across disclosed rounds, with strategic investors including Legend Capital, Shanghai International Asset Management, Beijing AI Industry Investment Fund, Guofang Innovation, National AI Industry Investment Fund, Matrix Partners China, Qiming Venture Partners, ZhenFund, and corporate backers Didi and Apple Funds.
