AWS Security Hub: Native Cloud Security Operations

If you have been working with AWS for any significant amount of time, you have likely watched environments grow from just a couple of accounts into a sprawl of complexity with dozens or hundreds of accounts, a huge variety of workloads, and, more critically, diverging configurations. That complexity sprawl is a necessary part of growth, but if you don't manage it properly, it'll create an engineering bottleneck in your organization.

At Caylent, we've helped customers manage this. Being recognized as the 2025 AWS Security Consulting Partner of the Year, along with our Migration and GenAI 2025 Partner of the Year awards, validates what we have been telling our clients for years: robust security isn't about building a fortress once, it’s about the ability to maintain a secure baseline across a landscape that is constantly shifting.

Traditionally, managing compliance across hundreds of accounts has required a patchwork of third-party tools, complex custom scripting, and often significant manual effort. Not anymore. We are proud to be a launch partner for AWS Security Hub, a native solution that streamlines how organizations manage their cloud security posture and run cloud security operations.

What is AWS Security Hub?

AWS Security Hub is a native control plane for cloud security operations on AWS. It ingests findings from native services and partners, correlates them, and produces exposure findings that help you identify real, exploitable risk. Exposure findings are generated by analyzing traits such as misconfiguration, reachability, sensitive data, and vulnerabilities. Those traits come from sources like AWS Security Hub CSPM control checks, Amazon Inspector, Amazon Macie, and others. The result is a prioritized queue that surfaces the resources most likely to be compromised.

AWS Security Hub will show near-real‑time updates in the console and API, graph-style potential attack paths for each exposure, and a unified resource view that lets you pivot from a resource to all associated findings. You can also define managed and custom insights to track trends or slice findings by fields that matter to your program.

Key Capabilities at a Glance

• Exposure findings: Correlate signals across misconfigurations, vulnerabilities, reachability, and sensitive data to identify critical risks for supported resource types (e.g., Amazon EC2, Amazon S3, AWS Lambda, Amazon EKS). The severity is derived from the number and combination of traits.
• Attack‑path visualization: Interactive view of how traits combine into a potential path to impact for a resource.
• Resource inventory: A consolidated resources view with per‑resource metadata and a findings pivot to streamline triage.
• Insights & analytics: Managed and custom insights that group findings by attributes and filters to monitor posture and operational KPIs.
• Control views: A consolidated controls page and optional consolidated control findings to reduce duplicate alerts when the same check exists in multiple standards.
• Coverage findings: Visibility into where Amazon GuardDuty, Amazon Inspector, Amazon Macie, and CSPM are enabled across accounts helps close detection gaps.

Unified Cloud Security Capabilities

AWS Security Hub correlates and enriches findings across accounts and Regions to surface complex risk scenarios that individual findings may not reveal on their own. By analyzing relationships between findings and resources, it automatically generates exposure findings that represent potential paths to impact (e.g., an internet‑reachable instance with exploitable software). Exposure findings are evaluated in near real-time and carry severities to support prioritization.

As inputs, AWS Security Hub analyzes signals from services such as Amazon Inspector, Amazon GuardDuty, Amazon Macie, and posture/control evaluations (e.g., AWS Security Hub controls), then connects related vulnerabilities, threats, and misconfigurations. The result is a prioritized view of risks, augmented by the attack path graph to visualize how exposure traits could be chained by an attacker.

In addition to correlation and visualization, AWS Security Hub provides pre‑built insights and dashboards that summarize exposures, threat trends, and coverage, helping teams answer “what changed and where to focus” without building custom reports for every audience.

Managing Security Alerts

AWS Security Hub supports centralized deployment and administration through AWS Organizations. You designate an administrator account to centrally view and manage findings across member accounts, while each member can still access its own findings. For Multi‑Region configurations, you enable cross‑Region aggregation by creating a finding aggregator and selecting a home Region. AWS Security Hub then replicates findings, insights, control‑compliance statuses, and security scores between linked Regions and the home Region, keeping updates synchronized in near real time.

To streamline downstream integrations, your Amazon EventBridge event bus in the administrator account’s home Region can publish events for findings across all member accounts and linked Regions. That allows you to connect ticketing, chat/notification, incident management, logging, and auto‑remediation tools once and route events with Amazon EventBridge rules.

Automation and Response

AWS Security Hub publishes every finding and update to Amazon EventBridge as Findings Imported V2 events. This lets you trigger ticket creation, chat notifications, incident management, SOAR playbooks, or targeted auto‑remediation in AWS Lambda and AWS Systems Manager, centralized in your home Region.

For data portability and analytics, AWS Security Hub uses Open Cybersecurity Schema Framework (OCSF), a standardized format for security data, to enable advanced security analytics that help you identify critical issues before they impact your operations. OCSF provides consistent formatting for security findings across various AWS services and partner integrations. By leveraging OCSF, Security Hub seamlessly integrates with your security tools and workflows. This standardized approach enhances your ability to identify patterns, trends, and anomalies across your cloud environment, leading to more effective security management.

Conclusion

With the release of AWS Security Hub, AWS has lowered the barrier to entry for robust, multi-account security. Now you can run your entire cloud security operation as a native AWS capability, rather than relying on a third-party tool.

As an AWS Security Consulting Competency Partner, Caylent is excited to see AWS continuing to invest in native security capabilities. Tools like AWS Security Hub allow us to spend less time configuring and combining security tooling for our clients and more time designing sophisticated threat detection and automated response strategies.

The service is generally available as of today. If you are using AWS Organizations, the path to better security operations in AWS has just been paved and lit for you.
