Top 7 Hong Kong CDN Providers in 2025 That Don't Require ICP Filing (With Reviews)

一、What is CDN?  
Think of CDN as "content delivery express". Imagine ordering stuff online and the seller stores goods in warehouses near your home for faster shipping. CDN works the same way—caching website content (pages, images, videos) on global servers. When users visit, they get data from the nearest node, which slashes loading times.

Hong Kong CDN Advantages

• No ICP Filing: Skip China's 20-day bureaucratic process—perfect for urgent launches
• Prime Location: 30-50% lower latency than EU/US nodes for Greater China users
• Regulatory Flexibility: Less strict content censorship (but stay legal!)
• Premium Connectivity: CN2/BGP lines ensure stable cross-border access
• Cost Efficiency: 40% cheaper bandwidth than Western providers

二、How to Choose a CDN Provider  
Like buying a smartphone, evaluate performance, security, and cost:

• Performance
  • Anycast Routing: Smart path selection (Cloudflare's specialty)
  • Dynamic Acceleration: TCP/UDP optimization for APIs (CDN5 cuts 60% latency)
  • Protocol Support: HTTP/3 + QUIC for unstable networks (StoneCDN rocks this)
• Security
  • DDoS Protection: T-level defense for finance (G-Core shines here)
  • WAF Rules: Cloudflare's million-rule firewall blocks hackers
  • Compliance: ISO 27001 for EU businesses (JQCDN's got you covered)
• Cost
  • Hidden Fees: Watch out for API calls/log storage charges
  • Tiered Pricing: JQCDN's 25% prepaid discount
  • Hybrid Billing: AWS' request-based pricing for high-concurrency apps
