SiS International

What SiS International does

SiS International Limited is a value-added distributor (VAD) of IT hardware and software, operating as a wholly-owned subsidiary of SiS International Holdings Ltd (SEHK:0529). Founded in 1983 and headquartered in Kowloon City, Hong Kong, the company distributes technology products from 40+ vendor partners across six categories: Cyber Security, Infrastructure, Networking, Data Management, Work Productivity, and Video Conference. Its primary markets are Hong Kong and Macau, with regional offices in Singapore and Thailand supporting broader Asia-Pacific activity. The vendor roster spans Western names (Kaspersky, Cybereason, Darktrace, Arista, HPE, Nutanix, Vertiv, Dell, HP, Epson, Thycotic/Delinea, Orca Security, SecurityScorecard, Wasabi) alongside Chinese-domestic vendors (H3C, Inspur, NSFOCUS (绿盟科技), TopSec (天融信), ZDNS, Transwarp (星环科技), Dameng (达梦数据库), WPS Office (金山办公), ZStack, SmartX, Leagsoft (联软科技), LogEase (日志易), River Security (瑞数信息), Sansec (三未信安), Netis (天旦), Chaitin Tech (长亭科技), Haiyi Security (海颐科技), Embedway (恒为科技), Dynarose (蔷薇灵动), CyberServal (薮猫科技), SecZone (开源网安), Betasoft (北塔软件), VEsystem, and AIStorm 亚信安全).

The business model combines traditional distribution (hardware and software resale) with value-added services that include pre-sales consultancy, solution design, proof-of-concept and vendor demonstrations, implementation, post-sales hardware/software maintenance, incident management tokens, and certified training. These services are delivered to an extensive network of channel partners, resellers, and system integrators, as well as directly to enterprise and institutional end-customers in government, financial services, telecommunications, education, data center, and broader commercial segments. Event-driven go-to-market activities (partner seminars, training workshops, and vendor showcases such as Maxhub Connect 2026, H3C Server Training, and the New Era Unleashed Data Infrastructure Seminar) are used to recruit and enable channel partners. Pricing is quote-based and not publicly disclosed; multi-year enterprise contracts are documented.

SiS earns revenue primarily through hardware and software resale margins, with a growing mix of cybersecurity subscriptions (endpoint protection, threat intelligence, detection-and-response, and supply-chain risk) and recurring professional services revenue. The company has accumulated multiple industry awards (Darktrace APAC Partner of the Year 2022, Darktrace Partner of the Year 2020, Nutanix Distributor of the Year 2019 and 2020 including individual awards, FireEye Top Distributor Greater China Region 2020, Lenovo DCG Value-Added Distributor of the Year 2020), supporting its positioning as a credible regional distributor in cybersecurity and hyperconverged infrastructure.
