Cloud and SaaS security assessment preparation guide
A cloud and SaaS security assessment goes much smoother when the organization prepares evidence before the review begins. The goal is to understand which tenants, subscriptions, applications, identities, administrators, data locations, integrations, logs, backups, and third parties are in scope, then collect proof that controls are configured and operating.

Why it matters
Prepare evidence before the assessment starts
Cloud and SaaS environments change quickly. Users create apps, integrations, sharing links, service accounts, cloud resources, storage locations, and administrative exceptions faster than traditional audit cycles can follow.
Preparation helps the assessment focus on real risk instead of discovery confusion. A good evidence package includes asset scope, identity controls, administrative access, data protection, logging, backup and recovery, security posture findings, vendor integrations, and open risk decisions.
Practical rule: Do not begin a cloud and SaaS assessment with only a list of subscriptions or apps. Prepare tenant-level evidence, identity and admin reviews, data-flow notes, logging exports, backup coverage, third-party integrations, and known exceptions with owners.
Review scope
What preparation should cover
Tenant and app scope
List cloud tenants, SaaS platforms, subscriptions, business owners, admin contacts, data types, and critical workflows.
Identity and access
Prepare MFA, privileged role, guest user, stale account, service account, and break-glass evidence.
Data protection
Review external sharing, public exposure, encryption, retention, DLP, sensitive data locations, and backup coverage.
Logging and alerts
Confirm audit logs, activity logs, security alerts, retention, SIEM forwarding, and incident response ownership.
Integrations
Inventory OAuth apps, service principals, API keys, vendor access, automation accounts, and delegated permissions.
Remediation evidence
Collect CSPM findings, tickets, owner assignments, exceptions, risk acceptance, and improvement roadmap.
Review matrix
Cloud and SaaS assessment readiness matrix
| Area | What to verify | Questions to answer | Evidence |
|---|---|---|---|
| Privileged administrator roles | Overprivileged or stale admins can expose cloud tenants, data, and identity systems. | Export admin roles, verify MFA, review break-glass accounts, remove stale admins, and document owner approval. | Who has administrative access and why? |
| External sharing and public exposure | Uncontrolled sharing can expose files, storage, reports, or SaaS data outside the organization. | Review sharing policies, public links, storage exposure, guest users, and sensitive data locations. | Where can external users access company data? |
| OAuth and API integrations | Third-party apps can retain broad permissions after the business need ends. | Inventory connected apps, permissions, owners, last use, vendor risk, and removal candidates. | Which applications have delegated or application permissions? |
| Logging gaps | Incidents are harder to investigate when logs are disabled, short-lived, or not centralized. | Confirm audit logging, retention, security alerts, SIEM forwarding, and investigation workflow. | Would logs support an investigation from the last 90 days? |
| Backup and recovery | Cloud and SaaS platforms may not protect against every deletion, ransomware, misconfiguration, or retention mistake. | Review backup scope, restore testing, retention, critical data coverage, and recovery ownership. | Can critical cloud data be restored within business requirements? |
Step-by-step review
Cloud and SaaS assessment preparation runbook
1
Define assessment scope
List tenants, subscriptions, SaaS apps, data locations, administrators, vendors, users, and business processes in scope.
2
Collect identity evidence
Export MFA coverage, admin roles, guest users, service accounts, stale users, break-glass accounts, and access review notes.
3
Review data and sharing
Document sensitive data locations, external sharing, public links, storage exposure, retention, encryption, DLP, and backup coverage.
4
Validate logs and alerts
Confirm audit logs, sign-in logs, cloud activity logs, alert routing, SIEM forwarding, retention, and incident response ownership.
5
Inventory integrations
Review OAuth apps, API keys, connected apps, service principals, automation accounts, vendor access, and delegated permissions.
6
Prepare remediation package
Organize CSPM findings, owner assignments, tickets, exceptions, risk acceptances, quick wins, budget needs, and executive summary.
Common risks
Common cloud and SaaS assessment preparation mistakes
Incomplete tenant inventory
Shadow tenants, unmanaged SaaS apps, and old subscriptions can hide risk from the assessment.
Only screenshots, no exports
Screenshots help, but exports and logs often provide better evidence for users, roles, settings, and findings.
Ignoring integrations
OAuth apps, API keys, automation accounts, and service principals often carry high-risk permissions.
No data owner list
Security decisions are weaker when nobody owns the data, application, or business workflow.
No known-risk register
Assessments are more productive when known gaps, exceptions, and open tickets are documented honestly.
No executive summary
Leadership needs concise risk, business impact, budget needs, quick wins, and owner assignments.

FAQ
Cloud and SaaS Security Assessment Preparation FAQ
What should be prepared before a cloud security assessment?
Prepare tenant inventory, admin role exports, MFA evidence, sharing settings, logs, integrations, backup coverage, CSPM findings, exceptions, and remediation tickets.
Should SaaS applications be included?
Yes. SaaS applications often contain critical business data and should be reviewed for identity, sharing, logging, integrations, and vendor access.
What evidence is most useful?
Exports of users, roles, logs, apps, findings, sharing settings, and tickets are useful, along with screenshots for important configuration screens.
How should known gaps be handled?
Document known gaps honestly with owner, risk, remediation plan, due date, compensating controls, and executive decision where needed.
Can IT Perfection help prepare for an assessment?
Yes. IT Perfection can help collect evidence, organize remediation, coordinate cloud operations, and prepare technical teams for review.
