CDN Providers
Japanese CDN providers store copies of your website on servers located closer to visitors so pages, videos, and downloads load faster. They also absorb sudden traffic surges so your main server stays responsive. Options range from pay-per-use plans for smaller sites to fixed-rate packages designed for heavy video streaming and live events.
Many providers include built-in security features alongside speed improvements, letting you manage performance and protection in one place.
DDoS
Distributed denial-of-service protection blocks large waves of malicious traffic before they can overwhelm your site, helping it stay online even during an attack.
WAF
A Web Application Firewall checks every incoming request and blocks common hacking techniques, such as code injection, before they reach your application.
