Overview
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.
Rackspace Technology, founded in 1998, offers a content delivery network (CDN) designed to accelerate content delivery by caching assets closer to users. The service integrates with Rackspace’s broader cloud offerings, including Cloud Files, and supports businesses needing reliable content distribution. It is primarily used by enterprises leveraging Rackspace’s managed cloud services, particularly those with complex infrastructure needs. The CDN is built to reduce server load and improve user experience through global content distribution.
Network & Architecture
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.
Rackspace CDN operates a global network with points of presence (POPs) across North America, EMEA, APAC, and Latin America, though specific POP counts are not publicly detailed. It leverages partnerships with major cloud providers and uses Akamai’s infrastructure for content delivery. The service is optimized for integration with Rackspace’s cloud storage but may have limited flexibility for standalone CDN use. Its global footprint ensures low-latency delivery for enterprise customers, with a focus on North America and EMEA.

Pricing
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.
Rackspace CDN operates on an enterprise-only model, with pricing typically bundled into broader Rackspace cloud contracts. No public per-GB pricing is available, and there is no free tier or pay-as-you-go option. Custom pricing requires contacting Rackspace sales for quotes tailored to enterprise needs.
Integrations & DevEx
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.
The CDN provides a robust API for managing services, with documentation available at https://docs.rackspace.com/docs/cdn. It supports programmatic control over caching, domains, and content refreshes. Real-time logs are available for monitoring, but there’s no public support for Terraform, SDKs, or CI/CD integrations. Migration tools are limited, primarily designed for integration with Rackspace’s Cloud Files.
When it fits
- Enterprises needing a CDN with strong security features like WAF and DDoS protection.
- Businesses in regulated industries (e.g., finance, healthcare) requiring robust compliance and bot mitigation.
- Organizations with global audiences benefiting from Imperva’s PoP distribution and low-latency delivery.
- When it fits:
- Enterprises already using Rackspace’s cloud services, seeking seamless CDN integration.
- Businesses needing global content delivery with a focus on North America and EMEA.
- Teams requiring API-driven CDN management and real-time logging.
- When it doesn’t:
- Small businesses or startups looking for pay-as-you-go or free-tier options.
- Users needing advanced security features like WAF or DDoS protection.
- Organizations prioritizing edge compute or video-specific CDN capabilities.
When it doesn’t
- Small businesses or startups seeking cost-effective, free-tier, or transparent pricing models.
- Developers needing extensive IaC support, such as Terraform or advanced CI/CD integrations.
- Companies focused on edge compute or serverless functions, which Imperva does not currently offer.
