What is Cloud Security Posture Management (CSPM)?

What it does

CSPM tools connect to cloud provider APIs and continuously check the configuration of cloud resources against security benchmarks and compliance frameworks. Core functions include:

• Detecting misconfigurations such as publicly exposed storage buckets, overly permissive IAM roles, and unencrypted databases
• Mapping findings to compliance frameworks such as CIS Benchmarks, SOC 2, PCI DSS, HIPAA, and ISO 27001
• Prioritizing risks by severity so teams fix the most dangerous issues first
• Alerting on configuration drift when a resource changes from a known-good state
• Some tools extend into Infrastructure as Code (IaC) scanning to catch misconfigurations before resources are deployed

CSPM operates without agents. It reads cloud control-plane data rather than running software inside workloads.

Why teams buy it

Cloud environments change fast. Developers provision resources in minutes, and a single misconfigured setting can expose sensitive data. CSPM automates the checks that would otherwise require manual audits. Teams buy it to:

• Pass compliance audits without building manual evidence-collection processes
• Reduce the window between a misconfiguration being introduced and being found
• Give security teams visibility across multiple cloud accounts and providers from one place
• Meet cyber insurance or regulatory requirements that demand continuous monitoring

What to look for

• Multi-cloud coverage: Support for every provider your organization uses, including AWS, Azure, GCP, and OCI
• Framework depth: The number and currency of built-in compliance frameworks
• Step-by-step fix instructions, or automated remediation options
