Cloud Security Posture Management

What Is CSPM?

Cloud Security Posture Management (CSPM) tools automatically assess your cloud environments against security best practices and compliance standards. They detect misconfigurations — like publicly exposed S3 buckets, overly permissive security groups, or unencrypted databases — that are responsible for the majority of cloud breaches.

Why CSPM Exists

Cloud infrastructure misconfigurations are the leading cause of cloud security incidents. The shared responsibility model means that while cloud providers secure the infrastructure, customers are responsible for configuring it securely. Common misconfigurations include:

• Public S3 buckets or Azure blob containers
• Security groups allowing unrestricted inbound access
• Unencrypted data stores and volumes
• Unused IAM credentials with excessive permissions
• Logging and monitoring not enabled
• Default credentials on cloud resources

Key CSPM Capabilities

• Configuration Assessment: Scan cloud resources against security benchmarks (CIS, NIST, PCI)
• Continuous Monitoring: Detect configuration drift in real time
• Multi-Cloud Support: Unified view across AWS, Azure, GCP, and other providers
• Compliance Mapping: Map findings to regulatory frameworks
• Remediation Guidance: Provide step-by-step fix instructions or auto-remediation
• Asset Inventory: Maintain a complete inventory of cloud resources
• Risk Prioritization: Rank findings by exposure, sensitivity, and exploitability

CSPM and CNAPP

CSPM is now commonly a component within CNAPP (Cloud-Native Application Protection Platform) rather than a standalone product. CNAPP adds workload protection, entitlement management, and code security to CSPM's posture management capabilities.
