About

21YunBox is a specialized enterprise performance overlay and managed compliance solution for Mainland China. Engineered for global stacks—including Sitecore, Adobe (AEM), Optimizely, Contentful, and Vercel—the platform enables international organizations to achieve local performance parity without requiring a separate codebase or costly infrastructure re-architecture. As a non-invasive stability layer, 21YunBox automates the resolution of "Great Firewall" bottlenecks. It identifies and rewrites blocked third-party dependencies (like Google APIs and YouTube) in real-time, replacing them with high-speed, China-friendly equivalents. Key Capabilities: Zero-Architecture: Maintain global origins (Azure, AWS, Vercel) while 21YunBox stabilizes delivery. Managed Compliance: End-to-end ICP Filing, PIPL security, and MIIT audits. Deep Video Optimization: High-speed delivery for YouTube/Vimeo assets. Fresh-by-Default: Instant visibility for CMS updates with zero manual syncing.
