Overview
CDNetworks, founded in 2000, is a global content delivery network (CDN) provider offering services for web performance, media delivery, and cloud security. Headquartered in Singapore, it serves industries like e-commerce, gaming, and media, with clients including Alibaba, Samsung, and Hyundai. Its CDN Pro (formerly CDN360) focuses on delivering static and dynamic content with enhanced security features. The company emphasizes strong network presence in Asia, particularly China, and provides solutions like DDoS protection and edge computing. CDNetworks is owned by Wangsu Science & Technology since 2017.
Viblast was a Bulgaria-based company founded in 2013 that specialized in peer-to-peer (P2P) video streaming solutions, offering Viblast PDN and Viblast Player for live and on-demand video delivery. It served broadcasters, content providers, and CDNs, leveraging WebRTC and HTML5 to enable plugin-free HLS and MPEG-DASH playback. The company aimed to reduce bandwidth costs and improve stream quality for high-concurrency live streams. As of 2023, Viblast is reported as out of business, with no active services or official website available.
Network & Architecture
CDNetworks operates over 2,800 Points of Presence (PoPs) across six continents, with a strong focus on the Asia-Pacific region, including China and India. Its network leverages global peering and an anycast architecture to optimize routing and reduce latency. The company holds an ICP Beian license, enabling compliant content delivery in Mainland China. Regional strengths include extensive coverage in APAC, but its North American and African footprints are less dense compared to competitors like Akamai or Cloudflare.

Pricing
CDNetworks uses a customized pricing model, typically enterprise-focused, with quotes based on data transfer, feature usage, and contract terms. Public pricing is not fully transparent, but estimates suggest $0.03–$0.15 per GB for data transfer and $0.005 per 10,000 HTTP/HTTPS requests. No free tier or pay-as-you-go options are publicly advertised; pricing requires contacting sales for a tailored quote. See https://www.cdnetworks.com/pricing/ for details.

Integrations & DevEx
CDNetworks supports Terraform for infrastructure-as-code, with OpenAPI Explorer for API integration. Its CDN Pro Portal and API provide access to real-time logs and analytics, facilitating monitoring and optimization. SDKs are not extensively documented, but the API-first design supports custom integrations. Migration tools are not explicitly mentioned, though the console supports cloning configurations for easier setup. CI/CD integration is possible via APIs but lacks native plugins for common pipelines.
—
When it fits
- Businesses needing strong CDN performance in Asia, especially China, due to CDNetworks’ ICP Beian license and extensive APAC PoPs.
- Enterprises requiring integrated security (WAF, DDoS, bot mitigation) alongside content delivery for e-commerce or gaming.
- Organizations leveraging edge computing for serverless applications with global reach.
—
When it doesn’t
- Small businesses or startups seeking pay-as-you-go or free-tier options, as CDNetworks focuses on enterprise contracts.
- Users needing dense PoP coverage in North America or Africa, where competitors like Cloudflare have broader reach.
- Developers requiring extensive SDKs or native CI/CD integrations, which are less emphasized compared to Fastly.
