RuCDN is a Russian cloud edge platform that helps businesses protect, accelerate and maintain the availability of websites and web applications. Its services can be connected through DNS or traffic proxying, without moving existing infrastructure or lengthy integrations. The platform combines a content delivery network (CDN) with L3–L7 DDoS protection, a web application firewall (WAF), AntiBot tools, managed DNS and monitoring. CDN caching and distributed edge nodes help deliver content closer to users and reduce the load on origin servers, while configurable security rules filter attacks, automated traffic and suspicious activity.

RuCDN serves e-commerce, fintech, media, SaaS, gaming and public-sector projects, from smaller websites to high-traffic enterprise systems. Customers can review traffic, attacks, cache performance and availability in a shared interface, and scale protection as demand changes. The company also provides 24/7 engineering support for setup, incidents and rule optimization. Plans include Start and Business packages, as well as individually priced Enterprise configurations, with costs based on traffic, selected modules and SLA requirements.
