Overview
Incapsula, now integrated under Imperva, is a cloud-based CDN platform focused on web application security, DDoS mitigation, and performance optimization. Founded in 2009 as a spin-off from Imperva, it provides services like web application firewalls (WAF), bot mitigation, and load balancing. The platform serves businesses of varying sizes, including high-traffic websites and enterprises like Wix and Siemens. Incapsula’s global network enhances site speed and security, leveraging intelligent caching and content optimization. It operates as a full proxy, sitting between the website and its host to deliver robust security and performance features.
Kingsoft Cloud, founded in 2012, is a leading cloud service provider in China, offering CDN, cloud storage, and computing services. It serves industries like gaming, video streaming, healthcare, and finance, with a strong focus on AI-driven solutions. The company operates as a subsidiary of Kingsoft Corporation and is listed on NASDAQ (KC) and HKEX (3896). Its customers include enterprises leveraging its infrastructure for high-performance computing and AI applications, particularly within the Xiaomi and Kingsoft ecosystems. As of 2025, it reports significant growth in AI cloud revenue and operates data centers globally.
Network & Architecture
Incapsula operates a global CDN with points of presence (PoPs) across the Americas (e.g., Atlanta, Dallas, Los Angeles), Europe (e.g., Amsterdam, London, Frankfurt), and Asia-Pacific (e.g., Hong Kong, Singapore, Tokyo). The network includes recent expansions in India (New Delhi, Mumbai). It uses intelligent caching, TCP optimization, and frequency analysis to prioritize frequently accessed files, reducing latency. Routing and peering details are not fully public, but the platform emphasizes high-capacity scrubbing centers (100+ Gbps per Behemoth scrubber) for DDoS mitigation. It performs well globally but has a stronger presence in North America and EMEA, with growing coverage in APAC and India.
Kingsoft Cloud operates data centers in mainland China, Hong Kong, Russia, Southeast Asia, and North America. Specific POP (Point of Presence) counts are not publicly disclosed, but the provider emphasizes a global footprint with strong coverage in APAC, particularly China. Its infrastructure supports high-performance computing for AI and gaming, with robust peering for low-latency delivery in the region. Limitations may include less extensive coverage in EMEA and LATAM compared to providers like Akamai or Cloudflare. The service is optimized for China’s regulatory environment, holding necessary licenses for operation.

Pricing
Incapsula offers a free tier for up to 10 pages, including CDN, IPv6 support, and basic bot protection. Paid plans start at $59/month (Pro) and $299/month (Business) per site, with enterprise plans customized. Pricing is pay-as-you-go (PAYG) with committed options for enterprises. DDoS protection significantly increases costs on higher tiers. Full details are at https://www.imperva.com/pricing/.
Kingsoft Cloud uses a pay-as-you-go (PAYG) model with enterprise-focused pricing, requiring custom quotes for most services. No free tier is publicly advertised, and pricing details are not fully transparent without contacting sales. Per-GB pricing for CDN or storage is not publicly listed, but the model supports scalability for large enterprises. See https://en.ksyun.com/pricing for more details.
Integrations & DevEx
Incapsula supports API-first integrations for configuration and monitoring, with real-time logs and log push for analytics. It lacks Terraform support or dedicated SDKs for CI/CD pipelines. The platform provides a dashboard for bot traffic and WAF alerts, but migration tools are limited, requiring manual configuration or support from Imperva for complex setups.
Kingsoft Cloud provides APIs for service management and real-time logs for monitoring. Documentation is available at https://endocs.ksyun.com/, covering CDN, storage, and compute services. Terraform support is not explicitly documented. SDKs are available for major programming languages, supporting integration with CI/CD pipelines. Migration tools for data transfer, such as Kingsoft Cloud Data Transmission Service (KDTS), assist with moving data between engines.
When it fits
- Businesses needing robust web security with CDN, especially for DDoS and bot mitigation.
- High-traffic sites requiring global performance with strong North American and EMEA presence.
- Enterprises seeking API-driven control and real-time monitoring for security events.
- Enterprises needing a China-licensed CDN with strong APAC coverage for gaming or video streaming.
- Businesses within the Xiaomi or Kingsoft ecosystems seeking integrated AI and cloud solutions.
- Organizations prioritizing AI-driven edge computing and high-performance infrastructure.
When it doesn’t
- Sites focused on video streaming or live content, as video-specific features like VOD or HLS/DASH are absent.
- Small projects needing lightweight, developer-centric CDN without security overhead.
- Budget-conscious users, as premium security features increase costs significantly.
- Small businesses or startups looking for a free tier or transparent, low-cost pricing.
- Companies requiring extensive POP coverage in EMEA, LATAM, or other non-APAC regions.
- Users needing advanced features like HTTP/3, DRM, or Terraform integration not currently offered.
