What Security Hub Aggregates

As you add security services, alerts pile up in many consoles. AWS Security Hub solves this by acting as a central aggregator: it collects findings from many AWS security services and partner tools into a single view. Instead of checking each service, you triage from one place.

Security Hub ingests findings from services like GuardDuty, Macie, Inspector, IAM Access Analyzer, and Firewall Manager, plus third-party products. It also runs its own automated security checks. The result is a unified backlog of everything wrong across your account.

Different services describe findings differently. Security Hub converts them all into one standard structure, the AWS Security Finding Format (ASFF), so every finding looks consistent regardless of origin. This normalization is what makes a single pane of glass possible.

Security Hub is not just a collector; it actively evaluates your account against security standards using automated checks. These checks produce their own findings about misconfigurations, giving you both incoming alerts and continuous posture assessment in one service.

Because findings are regional, Security Hub offers a cross-Region aggregation feature that rolls findings from many Regions into one aggregation Region. This gives a security team a true single view across the whole footprint rather than per-Region silos.

Like GuardDuty, Security Hub supports a delegated administrator and AWS Organizations integration. One security account can aggregate findings from every member account, with auto-enable for new accounts. This combines with cross-Region aggregation for organization-wide visibility.

By deduplicating and normalizing, Security Hub cuts down noise and helps analysts see the real picture. Related findings can be grouped, and consistent severity makes prioritization across sources fair. The goal is fewer, clearer, more actionable alerts.

Security Hub integrates with EventBridge, so aggregated findings can trigger automated responses or be forwarded to ticketing and chat tools. This turns the central hub into the launch point for response workflows, not just a dashboard.

Think of the flow as detect, aggregate, investigate, respond. GuardDuty and others detect; Security Hub aggregates and scores; Detective investigates; EventBridge and Lambda respond. Security Hub is the central nervous system tying detection to action.

The findings Security Hub aggregates span categories: threat detections from GuardDuty, sensitive-data discoveries from Macie, vulnerability findings from Inspector, and access findings from IAM Access Analyzer. Pulling threats, vulnerabilities, data risks, and access risks into one place is what makes Security Hub a true single pane for security posture.

To pull in a service's findings, that service must be enabled and integrated with Security Hub. Many AWS sources integrate automatically once you turn Security Hub on; partner products integrate through the integrations page. A common gap is expecting findings from a source you never enabled, so confirming active integrations is part of any aggregation setup.

Pick the aggregation service.

Security Hub centralizes and normalizes findings from GuardDuty, Macie, Inspector, Access Analyzer, and partners into the ASFF format, while also running posture checks against standards. It supports cross-Region and cross-account (delegated admin) aggregation and feeds EventBridge for response, serving as the single pane of glass for security findings.
