AWS Security Health Check – Multi-Account Assessment

Multi-account AWS security visibility is a critical challenge for organisations managing complex AWS environments. Most customers use AWS Security Hub, AWS GuardDuty and AWS Inspector for infrastructure scanning, but these services provide point-in-time snapshots and lack integrated application-layer visibility. CirrusHQ AWS Security Health Check closes that gap by combining multi-account infrastructure posture assessment (powered by CirrusHQ Acuity, which integrates with Security Hub, GuardDuty and Inspector findings) with AI-driven application-layer penetration testing (using AWS Security Agent, formerly Frontier Agent). In a single 3-5 day engagement, you receive a consolidated report showing infrastructure misconfigurations, IAM over-permissions, application vulnerabilities and compliance gaps, all deduplicated, prioritised by business impact, and mapped to remediation effort.

The Health Check runs in two complementary layers. Layer 1 uses CirrusHQ Acuity to provision a temporary, read-only connection to your AWS accounts via cross-account IAM roles, aggregating findings from Security Hub, GuardDuty and Inspector, then adding proprietary IAM health analysis (privilege escalation detection, unused role identification, stale credential analysis). Layer 2 deploys AWS Security Agent to test your internet-facing AWS-hosted applications (EC2, ECS, EKS, Lambda, API Gateway, CloudFront and similar services) for OWASP Top 10 vulnerabilities, API security issues, AWS-specific misconfigurations (S3 permissions at the application layer, EC2 metadata endpoint exposure via SSRF, over-permissive CORS) and multi-tenancy isolation, critical for SaaS customers. All findings are triaged, false positives removed, and mapped to infrastructure context. Compliance frameworks supported: CIS AWS Foundations, FSBP, SOC 2, ISO 27001, HIPAA, PCI DSS. The assessment follows the same structured two-layer methodology CirrusHQ applies in AWS Security Health Improvement Program (SHIP) baseline engagements, so the output is directly reusable whether or not you pursue SHIP participation.

Outcomes include an executive security scorecard, a multi-account IAM risk register, a prioritised findings report with CVSS scores, and a remediation roadmap with effort estimates, ready for immediate action. This is built for AWS customers with 2+ accounts seeking baseline security visibility, regulated industries preparing for compliance audits, organisations building a security foundation, and SaaS platforms on AWS needing multi-tenancy isolation validation. Customers typically progress to CirrusHQ Remediation Sprints for high-priority findings, or to Managed Security Compliance for ongoing improvement.
