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.
Universal CDN, founded in 2015 and headquartered in Sofia, Bulgaria, offers a global content delivery network focused on delivering web content, video streaming, and live media. It serves businesses ranging from small startups to large enterprises, particularly those needing video-on-demand and live streaming capabilities. The service emphasizes an API-first approach, enabling developers to integrate and manage CDN services programmatically. Universal CDN supports a variety of use cases, including e-commerce, media, and gaming, with a focus on performance and real-time analytics.
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.
Universal CDN operates a global network with points of presence (PoPs) across North America, Europe, Asia-Pacific, and Latin America. Specific PoP counts are not publicly disclosed, but the provider claims broad coverage with optimized routing for low latency. It leverages partnerships with major ISPs for peering, enhancing delivery speeds. The service is particularly strong in Europe and North America but has less presence in Africa and the Middle East, which may limit performance in those regions.

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.
Universal CDN offers a pay-as-you-go (payg) model with no minimum commitments, suitable for variable traffic needs. Pricing starts at approximately $0.05 per GB for standard delivery, with discounts for higher volumes. A free trial is available for testing, and enterprise plans are offered for custom needs. Detailed pricing is available at https://www.ucdn.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.
Universal CDN provides an API-first design for seamless integration with developer workflows. It supports real-time logs for immediate performance insights but lacks Terraform support or advanced IaC tools. SDKs are available for common programming languages, facilitating integration with CI/CD pipelines. The platform does not offer built-in migration tools but provides documentation for transitioning from other CDNs.
