What this external audit tool reviews

Cloud and SaaS platforms can expose sensitive data without traditional firewall changes. This tool helps review public resources, external sharing, admin access, guest accounts, and conditional access controls across modern cloud services.

This free tool gives an initial readiness view based only on your answers. It helps identify practical gaps, missing evidence, and next steps before a deeper external security audit, vulnerability assessment, penetration test, or vCISO review.

Cloud Public Exposure

Azure, AWS, Google Cloud, storage, and hosted apps.

SaaS and Sharing

Microsoft 365, external sharing, guest users, and third-party apps.

Identity Controls

MFA, conditional access, admin roles, and risky access.

Cloud and SaaS External Exposure Assessment: what to review before a formal audit

The Cloud and SaaS External Exposure Assessment helps business owners, IT managers, CISOs, compliance leaders, and Southern California organizations review a narrow control area before a deeper cybersecurity audit, compliance readiness review, cyber insurance discussion, or vCISO planning session. This page is intentionally focused on assessment and readiness intent, not broad consulting keywords, so it can support the main OC Security Audit service pages without competing with them.

Use this page to identify evidence gaps, weak configurations, missing ownership, and remediation priorities related to public storage, SaaS admin portals, identity federation, OAuth apps, cloud DNS, and externally shared files. The strongest result comes from comparing the answers against real evidence such as screenshots, exported settings, logs, tickets, policies, diagrams, vendor records, backup reports, access reviews, and recent remediation activity.

What this assessment reviews

  • Public storage, shared links, exposed cloud services, SaaS guest users, and admin portals
  • OAuth applications, API tokens, service principals, external collaborators, and delegated permissions
  • Identity federation, MFA, conditional access, privileged roles, and break-glass access
  • Cloud logging, alerting, configuration baselines, and evidence for high-risk settings

Technical areas to validate

  • Review Microsoft 365, Entra ID, Azure, AWS, Google Cloud, and SaaS admin settings from the live portals
  • Export risky users, guest users, enterprise apps, shared files, public endpoints, and storage permissions
  • Use cloud-native policy, posture management, and audit logs to validate drift from baselines
  • Prioritize remediation for public data, privileged access, weak authentication, and unmanaged third-party apps

Implementation should start with a clear control owner, a documented current state, and a short remediation backlog. Prioritize gaps that affect internet exposure, privileged access, regulated data, business continuity, audit evidence, ransomware resilience, or executive risk reporting. Where a gap cannot be fixed quickly, document the exception, business owner, compensating control, and review date.

This tool is for initial guidance only and does not replace a professional cybersecurity audit, compliance assessment, penetration test, technical validation, or legal/compliance review. For a deeper review, use the result as a starting point for an OC Security Audit engagement with Ali Hassani, CISO, or request help through OC Security Audit contact.

Keyword separation note: this page targets the long-tail assessment intent “Cloud and SaaS External Exposure Assessment” and should not be optimized as a replacement for the broader cloud security consulting page or service topic.
