Alibaba Cloud Security Center is a Cloud-Native Application Protection Platform (CNAPP) that identifies, analyzes, and warns of security threats in real time. It integrates Cloud Workload Protection Platform (CWPP), Cloud Security Posture Management (CSPM), Cloud Infrastructure Entitlement Management (CIEM), and SIEM & SOAR capabilities into a unified platform. It protects servers, containers, serverless workloads, data centers, and cloud-native applications across Alibaba Cloud, hybrid cloud, and multi-cloud environments. Key capabilities include anti-ransomware protection, vulnerability scanning and one-click fixing with snapshot-based recovery, web tamper proofing, virus detection and removal, and threat detection powered by over 380 detection models aligned to the MITRE ATT&CK framework. CSPM baseline checks cover more than 700 configuration check items across more than 70 cloud services. Container security spans the full lifecycle from image construction and scanning to runtime threat detection and baseline compliance. The platform supports agentless detection, lightweight agent deployment, and centralized management of multi-cloud and on-premises servers from a single console. An Agentic SOC capability is also included. A Basic Edition is available free of charge, with paid tiers for Host Security (Enterprise Edition) and Container Security (Ultimate Edition) billed on a per-server or per-core monthly basis.
