Yes. UD (UDomain Web Hosting Company Limited) was founded in Hong Kong in 1998, headquartered at 18/F, Kinox Centre, 9 Hung To Road, Kwun Tong, Kowloon. Its 100+ engineers are all in Hong Kong, and sales, technical and billing lines are answered by the local team. UD was among the first government-certified public-cloud providers in Hong Kong and has won local awards including a Customer Service Award at the Hong Kong Awards for Industries and outstanding cybersecurity management service awards.
Three main differences. First, UD offers AI, blockchain, cloud, security and CDN under one roof, integrated by one team, removing multi-vendor coordination. Second, UD engineers are 100% local and never outsourced, with incident response in under 15 minutes. Third, since 1998 UD has served only Hong Kong and APAC, designing products around local compliance (PDPO, HKMA, ISO 27001) and language (Traditional Chinese, Cantonese), not a localised version of an overseas platform.
UD serves retail and e-commerce, finance and professional services, government and NGOs, education, manufacturing and logistics, and media and advertising. Its 25,000+ customers include MTR, Swire, city’super, UNICEF Hong Kong, the Consumer Council, the Hong Kong Housing Society and Phoenix TV. Each industry is matched with the right solution mix and compliance advisors.
First, one engineering team integrates across solutions, e.g. AI staff reading and writing cloud data, or CDN connecting to the security WAF, with no multi-vendor coordination on your side. Second, one contract, one bill and one support process make billing and compliance audits simpler. Third, combined solutions earn bundled pricing, negotiable across startup, enterprise and custom plans.
