Cloud security posture management (CSPM)

What is cloud security posture management (CSPM)?

Cloud security posture management (CSPM) is a set of tools and practices designed to identify, monitor, and remediate security risks in cloud environments, including hybrid and multi-cloud environments. It helps organizations maintain visibility and control over cloud configurations across different cloud models as environments scale and change.

How CSPM works

CSPM combines automated tools with defined security practices to continuously assess and manage cloud configuration risk. CSPM tools integrate with cloud service providers to collect configuration and metadata from cloud resources and evaluate it.

CSPM practices then define how these findings are handled. They include establishing approved configuration standards, assigning ownership for remediation, prioritizing risks based on impact, and tracking posture improvements over time. These practices ensure findings are consistently reviewed and resolved rather than treated as one-off alerts.

Common cloud risks CSPM detects

CSPM is commonly used to detect:

• Misconfigurations: Incorrect or insecure cloud resource settings, such as public storage access or disabled encryption.
• Excessive permissions: Identity or service roles granted broader access than necessary.
• Data exposure: Cloud data stores that are unintentionally accessible from the internet or unauthorized networks.
• Visibility gaps: Untracked cloud assets, unclear ownership, or unmanaged configurations.
• Account and identity risks: Suspicious access activity, privilege escalation, or compromised credentials.
• Compliance violations: Cloud configurations that do not meet regulatory or internal policy requirements.

Benefits of using CSPM

CSPM continuously assesses cloud environments for configuration risks. It also supports regulatory compliance by evaluating cloud configurations against established standards such as the Health Insurance Portability and Accountability Act (HIPAA) and the Payment Card Industry Data Security Standard (PCI DSS).

By automating configuration checks, CSPM reduces the likelihood of human error during deployment and ongoing changes, and it strengthens access and identity management by highlighting opportunities to tighten permissions.

Limitations of CSPM

CSPM has several inherent limitations that define what it can and cannot address:

• Configuration-focused scope: Evaluates cloud configuration and control plane settings, not runtime threats or active attacks.
• Limited threat detection: Doesn’t detect malware, exploits, or suspicious workload behavior.
• Alert volume: Can generate large numbers of findings that require tuning and prioritization.
• Cloud-only coverage: Focuses on cloud environments and doesn’t protect on-premises infrastructure.
• Policy dependency: Effectiveness depends on the quality and relevance of defined security policies.

CSPM vs. other cloud security tools

CSPM usually works alongside other tools that address different layers of cloud security, including:
