What It Is

CloudsRubik is a high-defense CDN provider that combines CDN acceleration with protection services. Its materials focus on HTTP/HTTPS DDoS protection for web assets, cloud WAF, L3/4 security services, and live-streaming media delivery. The target use cases lean toward cross-border websites, gaming, financial trading, e-commerce, and live-streaming businesses.

Core Capabilities and Node Coverage

In terms of nodes, CloudsRubik claims to have 2,800+ nodes worldwide and an intelligent scheduling system, allowing users to access static resources from nearby locations. It also supports specifying cached content and cache duration, as well as automatic migration of cache hotspots. Disclosed regions include Hong Kong, Taiwan, Singapore, Japan, South Korea, and the United States. Its Hong Kong nodes emphasize 150G+ Mainland/Hong Kong network redundancy, multiple SLA direct routes, and CN2-GIA, with no ICP filing required; its U.S. nodes mention 5T+ network redundancy and 2T+ protection, while its Japan nodes are connected to a 4T+ protection system.

Security and Streaming Features

Security is its main selling point: it offers always-on DDoS protection, combined with cloud WAF, bot management, and L3/4 security services to defend against various network threats. For streaming, it supports RTMP, RTSP, HLS, and DASH, with LLHLS and LLDASH said to be coming soon. It also supports adaptive bitrate transcoding for desktop, mobile, tablet, and TV devices.

Pricing and Ease of Use

The materials do not disclose specific pricing, plans, traffic quotas, or bandwidth unit prices. They only state that users should contact customer service to choose a high-defense CDN plan, and that free testing is available. The onboarding process is fairly traditional: enable the security service, add the IP/domain and origin IP, configure forwarding rules and protection policies, then update CNAME/DNS records to point to the CDN. CloudsRubik claims setup can be completed in about 5 minutes and provides 24×7 technical support.

Pros, Cons, and Who It’s For

Its strengths are the relatively detailed descriptions of Asia-Pacific cross-border routes, especially the Hong Kong nodes designed with Mainland China connectivity in mind. It also bundles CDN, DDoS protection, WAF, and live-streaming capabilities, making it suitable for high-risk, high-concurrency businesses. The drawbacks are the lack of key information such as pricing, SLA, control panel, API, logs, certificates, and billing dimensions, while its protection metrics also lack third-party verification. If your business prioritizes low-latency cross-border access and strong DDoS protection, it may be worth testing as a candidate. If you need transparent pricing, mature compliance support, and mainland China ICP-filed nodes, you may want to compare it with Cloudflare, Akamai, Fastly, 阿里云, 腾讯云, or 华为云 CDN. Availability from China is not directly stated in the materials; Hong Kong nodes may help with Mainland China access, but real-world testing is still necessary.
