ESA reduces the average end-to-end network latency between points of presence (POPs) worldwide to 50 milliseconds.
Why ESA?
Ultra-low latency
Reduces the average global end-to-end latency between Points of Presence (POPs) to just 50 milliseconds.
Offshore CDN
Achieve near-native onshore performance—40% faster than sites using CDNs near China alone.
Security protection for all services
Mitigate multi-Tbit/s DDoS attacks while blocking HTTP floods in one interface.
Free SSL/TLS certificates
Provides free certificates with auto-renewal, eliminating certificate O&M and costs.
Simplified access
Reduces DNS configuration time by 50% compared to traditional methods.
Cloud-native serverless deployment
Build faster with ER, KV - the serverless platform unifying compute & storage for Deno/Node.js developers.
