Alibaba Cloud Certificate Management Service is a full lifecycle SSL/TLS certificate management platform that partners with globally recognized Certificate Authorities (CAs) to provide certificate application, issuance, deployment, monitoring, and automated renewal. The service supports three certificate types: Domain Validation (DV), Organization Validation (OV), and Extended Validation (EV), issued by CAs including DigiCert, GlobalSign, GeoTrust, Rapid, and Alibaba Cloud's own CA. Certificates can be deployed directly to Alibaba Cloud services via a web console. The platform includes automated expiry detection and renewal, real-time certificate status monitoring, and alerting. A public domain monitoring feature tracks HTTPS connection availability, certificate chain validity, and issues alarms. An HTTPS Acceleration Gateway integrates SSL certificates with Alibaba Cloud CDN for encrypted content delivery. Free utility tools are provided for SSL certificate format conversion and certificate status detection. Full lifecycle management is also accessible via API, supporting certificate purchase, application, issuance, download, and upload operations. The service addresses use cases including HTTPS encryption for websites, apps, and mini programs; identity authentication; protection against man-in-the-middle attacks and phishing; PCI DSS compliance; and data integrity during transmission. Pricing starts at $66 USD/year for DV certificates and $1.95 USD/year for domain monitoring.
