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 provider focuses on accelerating website performance, optimizing images, and providing detailed analytics through real-time logs. Its services are designed to be accessible via an API-first approach, enabling seamless integration for developers.

The company emphasizes straightforward pricing and ease of use for performance-focused content delivery.
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.
Transparent CDN operates a global network with points of presence (POPs) across North America, Europe, Asia, and Latin America, though specific POP counts are not publicly disclosed. The provider leverages HTTP/3 and TLS 1.3 for efficient and secure content delivery. Its architecture supports real-time traffic analytics, which aids in performance monitoring. The network is optimized for general web content and image delivery but lacks specialized capabilities for video streaming or edge computing. Regional strengths include Europe and North America, with growing coverage in Asia and Latin America.

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.
Transparent CDN uses a pay-as-you-go (PAYG) model with no minimum commitments, making it accessible for small to medium-sized businesses. Pricing is based on data transfer and requests, though specific per-GB rates are not publicly listed. A free trial is available for testing the service.

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 API-first design supports integration with developer workflows, offering programmatic access to configuration and analytics. Real-time logs are available through the Transparent Edge dashboard, aiding in performance monitoring. The provider does not support Terraform or other Infrastructure-as-Code tools, and no SDKs or CI/CD integrations are documented. Migration tools are not explicitly offered, but the API simplifies onboarding for developers familiar with programmatic setups.
