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 solves this gap by combining multi-account infrastructure posture assessment (powered by CirrusHQ Acuity, which integrates with AWS 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. This assessment uses the same rigorous processes and techniques employed in the AWS Security Health Improvement Program (SHIP) baseline phase, making it the ideal security foundation for any AWS customer regardless of SHIP participation.

The Health Check is structured 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. Acuity aggregates findings from AWS Security Hub, AWS GuardDuty, and AWS Inspector, then adds 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 (running on EC2, ECS, EKS, Lambda, API Gateway, CloudFront, and similar AWS services) for OWASP Top 10 vulnerabilities, API security issues, AWS-specific misconfigurations (S3 permissions via 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. This same structured, two-layer approach is the foundation of SHIP baseline assessments, ensuring you receive enterprise-grade security analysis aligned with AWS best practices.

Outcomes include an executive security scorecard, multi-account IAM risk register, prioritised findings report with CVSS scores, and a remediation roadmap with effort estimates-ready for immediate action. This offering is ideal for AWS customers with 2+ accounts seeking baseline security visibility, regulated industries preparing for compliance audits, organisations building security foundations independently or as part of SHIP programme participation, and SaaS platforms on AWS requiring multi-tenancy isolation validation. The Health Check delivers the same assessment rigour as SHIP baseline phase engagement, enabling any AWS customer to achieve enterprise-grade security visibility. Customers typically progress to CirrusHQ Remediation Sprints for high-priority findings or Managed Security Compliance for ongoing AWS security improvement aligned to SHIP sustain phase methodology.
