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.
KeyCDN is a content delivery network (CDN) provider founded in 2012, headquartered in Wilen, Switzerland. It specializes in accelerating the delivery of web content, such as HTML, JavaScript, images, and videos, through a global network of edge servers. The service is designed for businesses of all sizes, from small blogs to enterprise websites, offering features like real-time analytics and DDoS protection. KeyCDN emphasizes ease of integration with a user-friendly dashboard and API, making it accessible for developers and SMBs. It supports a wide range of use cases, including e-commerce, media, and gaming, with a focus on performance and security.

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.
KeyCDN operates over 50 points of presence (POPs) across North America, Europe, Asia-Pacific, Latin America, and other regions, ensuring global coverage. Its network leverages SSD storage and HTTP/3 for efficient content delivery. The service uses a tiered caching system and supports origin shielding to reduce load on origin servers. KeyCDN has strong peering agreements with major ISPs, optimizing latency and throughput. Its regional strengths include robust performance in North America and Europe, though coverage in Africa and parts of Asia may be less extensive compared to larger providers like Cloudflare or Akamai.

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.
KeyCDN uses a pay-as-you-go (PAYG) model with no minimum commitments, making it SMB-friendly. Pricing starts at $0.04 per GB for the first 10 TB in North America and Europe, with higher rates for other regions like Asia ($0.14/GB) and Oceania ($0.19/GB). A 30-day free trial includes 10 GB of traffic. Additional features like DDoS protection are included at no extra cost, though custom SSL certificates may incur fees. Full details are available at https://www.keycdn.com/pricing.

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.
