Overview
CacheFly, founded in 2002 and based in Chicago, IL, is a content delivery network (CDN) provider specializing in high-performance delivery of static and dynamic content. It serves businesses in video streaming, gaming, software distribution, and e-commerce, emphasizing speed and reliability. CacheFly pioneered TCP Anycast routing in 2002, which optimizes traffic delivery to the nearest point of presence (PoP). Its customers range from startups to enterprises seeking efficient content delivery. The company has gained attention for capitalizing on recent CDN industry consolidation, positioning itself as an alternative to providers like StackPath and Lumen Technologies.
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.
Network & Architecture
CacheFly operates over 75 points of presence (PoPs) across all seven continents, with a strong presence in North America, Europe, Asia, South America, Australia, Africa, and the Middle East. Its network uses TCP Anycast for efficient routing, ensuring low-latency delivery. CacheFly reports a 98% cache hit ratio, with 100% availability for its S.O.S. (Storage Optimization Service) customers. The network is optimized for high-throughput use cases like large file downloads and media streaming. It has a notable footprint in Latin America compared to some competitors but may have fewer PoPs in certain regions compared to larger providers like Cloudflare or Akamai.
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.

Integrations & DevEx
CacheFly provides an API-first platform for configuration and management, with comprehensive documentation at https://www.cachefly.com/docs/. Realtime logs and analytics support performance monitoring, and log push enables integration with external systems. A dedicated Slack channel is available for enterprise accounts to ensure responsive support. Migration guides are provided for customers transitioning from StackPath and Lumen Technologies, including self-service setup and white-glove onboarding for accounts using over 150TB monthly. Terraform support is not documented.
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.
When it fits
- Businesses needing high-throughput CDN for video streaming, gaming, or large file downloads, particularly with global audiences.
- Companies migrating from StackPath or Lumen Technologies, leveraging CacheFly’s dedicated transition support.
- Developers seeking an API-first CDN with flexible pricing and a free tier for testing or small-scale projects.
- 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.
When it doesn’t
- Organizations requiring advanced edge compute or serverless functions, which CacheFly does not currently offer.
- Users needing robust WAF, bot mitigation, or rate-limiting features, as these are not publicly documented.
- Companies focused on China-specific delivery, where CacheFly lacks a specialized license compared to providers like Tencent CDN.
- 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.
