Overview
China Telecom Corporation Limited, a state-owned telecommunications provider, operates one of China’s largest content delivery networks, leveraging its extensive infrastructure to optimize content distribution. Founded in 2002, it serves major internet portals and enterprises, including Tencent QQ, Baidu, Sina, and Weibo. The CDN is integrated with China Telecom’s backbone networks, ChinaNet and CN2, to deliver low-latency services across China and globally. It caters to businesses requiring compliance with China’s strict internet regulations, such as ICP licensing, and supports a range of applications from web content to streaming media.
Imperva provides a cloud-based CDN integrated with its Web Application and API Protection (WAAP) platform, focusing on security and performance. The service includes content caching, load balancing, and global Points of Presence (PoPs) to deliver low-latency web experiences. It offers robust DDoS protection, a Web Application Firewall (WAF), and bot mitigation, making it suitable for enterprises prioritizing security. Imperva serves industries like finance, healthcare, and e-commerce, with clients such as Mediolanum and Vodafone. The company, founded in 2002 and headquartered in San Mateo, California, was acquired by Thales in 2019. Its CDN is part of a broader cybersecurity suite, emphasizing secure content delivery.
Network & Architecture
China Telecom CDN operates points of presence (PoPs) across 11 countries, with 15 cities including Sydney, Hong Kong, Tokyo, and Amsterdam. Its domestic strength lies in partnerships with local ISPs like China Unicom and Zenlayer, ensuring robust connectivity within mainland China. The network supports over 1–5 Tbps in traffic capacity, with 788 IP ranges in China alone. Limitations include restricted operations in the U.S. due to FCC orders citing national security concerns, impacting its ability to serve American customers directly. Its global reach is strong in APAC but less comprehensive in EMEA and LATAM compared to providers like Cloudflare or Akamai.
Imperva operates a global network with PoPs in North America, EMEA, APAC, and LATAM, including data centers in cities like Tokyo, New Delhi, and Miami. The exact number of PoPs is not publicly disclosed, but the network supports traffic rerouting during maintenance to ensure availability. It uses machine learning for dynamic caching and integrates with major peering partners for optimized routing. Regional strengths include North America and EMEA, with ongoing expansions in APAC and LATAM. Maintenance schedules, such as the August 2025 migrations in Hong Kong and Paris, ensure minimal disruption for Cloud WAF customers. Limitations include less transparency on PoP counts compared to competitors like Cloudflare.

Pricing
Pricing details are not publicly disclosed and typically involve enterprise-level contracts tailored to customer needs. No pay-as-you-go (PAYG) or free-tier options are documented. Businesses should contact China Telecom directly for quotes, as pricing varies based on traffic volume and service requirements.
Imperva uses a pay-as-you-go (PAYG) model with enterprise-focused pricing, typically requiring custom quotes. No free tier or public per-GB pricing is available, as plans are tailored for high-security use cases. Volume-based discounts are offered for committed contracts. Pricing details are available at https://www.imperva.com/pricing/. The model suits large organizations but may be cost-prohibitive for smaller businesses.
Integrations & DevEx
China Telecom CDN provides API-first access for configuration and management, with real-time logging for performance monitoring. Terraform or specific SDKs for CI/CD pipelines are not documented. Migration tools or support for transitioning from other CDNs are not publicly detailed, but partnerships with providers like Conversant suggest integration capabilities for international businesses.
Imperva provides APIs for configuration and management, supporting an API-first approach. Realtime logs and analytics are accessible via the Imperva Management Portal, with log push for integration into external systems. No public documentation confirms Terraform or specific SDK support, limiting Infrastructure-as-Code (IaC) options. Migration tools are not emphasized, but the platform supports standard CDN configurations. Developers may find the API robust but less flexible for CI/CD pipelines compared to Fastly or Akamai.
When it fits
