AWS Security Hub and Security Hub CSPM are closely related, but they play distinct roles in AWS security strategy.
What is AWS Security Hub?
AWS Security Hub is a unified cloud security platform. Its primary role is to aggregate, correlate, and prioritize security findings from various AWS services — such as Amazon GuardDuty, Amazon Inspector, and Amazon Macie — as well as select third-party providers. Security Hub provides a comprehensive dashboard where security teams can view exposures, automate responses, and track remediation status across their AWS accounts.
Key Features of AWS Security Hub:
- Centralized findings aggregation (from sources like GuardDuty, Inspector, CSPM, etc.)
- Automated response orchestration via EventBridge
- Attack path correlation and prioritized risk analysis
- Unified dashboard with actionable insights
- Uses OCSF (Open Cybersecurity Schema Framework) for standardized findings
What is Security Hub CSPM?
Security Hub CSPM stands for Cloud Security Posture Management. It focuses specifically on evaluating cloud resource configurations against best practices and compliance frameworks such as CIS, PCI DSS, or NIST. CSPM functionality runs automated, continuous checks to identify misconfigurations, policy violations, and compliance risks.
Key Features of Security Hub CSPM:
- Automated posture and compliance checks (FSBP, CIS, PCI DSS, NIST, etc.)
- Continuous cloud resource monitoring
- Security scoring and detailed compliance reporting
- Uses AWS Security Finding Format (ASFF)
- Seamlessly integrates with Security Hub for unified operations
How Are They Different?
How Do They Work Together?
Think of Security Hub as the dashboard that sees everything. CSPM is the engine running compliance and configuration checks in the background. When you enable CSPM, its findings — such as misconfigured S3 buckets, permissive security groups, or non-compliant IAM policies — are fed into Security Hub, where they’re surfaced, correlated with other risks, and prioritized for response.
Security Hub enables workflows and automation (via EventBridge, Lambda, or external tools) so security teams can address exposures rapidly, track remediation, and demonstrate compliance.
When Should You Use Each Service?
- Enable CSPM if you need continuous compliance monitoring, resource configuration checks, or detailed reports for frameworks like CIS, PCI DSS, or NIST.
- Enable Security Hub if you want a single pane of glass, automated response workflows, and correlation across all your AWS security services.
Best Practice: Most organizations should enable both. CSPM ensures your AWS environment adheres to security best practices, while Security Hub gives you the operational control and visibility to manage real-world cloud security risks.
Summary
- AWS Security Hub is the centralized cloud security analytics and response platform.
- Security Hub CSPM is the posture management and compliance checking core.
- Together, they deliver complete visibility, automated compliance, and actionable insights.
By understanding these differences and how the solutions complement each other, you can build a robust, automated, and scalable cloud security strategy that delivers real-world protection and compliance.

"This naming overlap has definitely been a 'self-inflicted wound' for a lot of teams. For those who have already enabled the new 'AWS Security Hub'—have you found the risk analytics and correlation features worth the effort of migrating your existing automation rules from the CSPM foundation? Or are you sticking to the legacy CSPM service for now?"
