Imperva (formerly Incapsula)

Imperva's CDN (originally Incapsula) is a security-first content delivery network. It excels at protecting web applications with its industry-leading WAF, advanced bot management, DDoS mitigation, and secure DNS. The CDN acceleration is a component of its broader application security suite. It is designed for enterprises in regulated industries (finance, healthcare) where security and compliance are paramount.

Pricing is enterprise-oriented. It ranks for its top-tier security capabilities, making it less a pure-play CDN and more a comprehensive security and performance platform for at-risk applications.
