CDNext is a domestic CDN from J-Stream Inc., a publicly listed company with a long track record in media delivery. It distributes content through servers placed across major domestic networks and data centers, routing traffic along the shortest path to end users.

The service stands out for its industry-specific plans, including options built for social media campaigns and local governments. It can speed up dynamically generated pages, resize images on the fly for different devices, and deliver internationally through servers in the US, Europe, Southeast Asia, and Oceania. Dedicated account managers and engineers provide hands-on support during and after deployment.

J-Stream holds both ISO 27001 and ISO 27017 (cloud security) certifications for CDNext operations, making it a strong choice for customers in finance, healthcare, and the public sector.

DDoS protection is built into the platform’s security options, helping absorb malicious traffic before it reaches the origin server.

An optional Web Application Firewall can be turned on directly within the CDN to block common web threats without requiring a separate security service.

J-Stream provides an English version of its corporate website with basic service information for international visitors.
