What FLK does

FLK (弗兰科信息), legally Hangzhou Fulanke Information Security Technology Co., Ltd. (杭州弗兰科信息安全科技有限公司), is a Chinese commercial cryptography specialist founded in 2010 in Hangzhou and operating as a wholly-owned subsidiary of Hangzhou DBAPPSecurity Information Technology Co., Ltd. (杭州安恒信息技术股份有限公司, SSE: 688023). The company designs and delivers a national cryptographic (国密) product portfolio built on Chinese state-mandated algorithms SM2, SM3, SM4, and SM9, covering hardware (server cryptographic machines, cloud server cryptographic machines with VSM virtualization, key management servers), software (cloud shield encryption module, transparent transmission encryption, SSL VPN gateway), and an orchestration layer called the Cryptographic Service Platform (密码服务平台) that delivers centralized, virtualized, elastic cryptographic services to cloud tenants.

FLK monetizes through two revenue streams: one-time license sales of cryptographic hardware and software products, and recurring cryptographic services (密码服务) priced on a usage basis for cloud customers needing elastic capacity. The go-to-market is enterprise field sales targeting government agencies (big data bureaus, public security, housing provident funds, education examination authorities), healthcare institutions (provincial hospitals), financial services (fund management companies), and enterprise communication customers, complemented by a strategic channel partnership with DingTalk that distributes the Anchong Miden Shield (安恒密盾) third-party encryption overlay to 20+ million users. Pricing is quote-based with multi-year contracts.

The product portfolio carries Commercial Cryptography Product Certification (商用密码产品认证证书) certificates, conforms to GB/T 39786-2021 information system cryptographic application requirements, and supports Xinchuang (信创) domestic-substitution stacks spanning hardware, software, chip, and operating system layers. The company has secured 70+ software copyrights and multiple patents, has been named a National High-tech Enterprise (2019), and has been selected into provincial commercial cryptography demonstration collections in Sichuan, Hubei, and Hainan.
