Google CASA
Security assessment for certain OAuth applications in the Google ecosystem.
SCOPE & APPLICABILITY
What the framework actually requires
Google CASA applicability depends on requested OAuth access and the assessment tier.
What matters in practice
Requirements depend on scope. These are the areas to evaluate, not a guarantee of certification or regulatory compliance.
OAuth scopes and data flows
Inventory OAuth permissions.
Application security controls
Review access, hardening, and findings.
Assessment evidence
Prepare evidence for the designated assessor.
An operational path, not a checkbox exercise
Translate requirements into accountable activities, evidence and reviewed controls.
Inventory OAuth permissions.
Review access, hardening, and findings.
Prepare evidence for the designated assessor.
APPLICABILITY
Who should assess this framework?
For certain applications accessing Google data through OAuth, especially sensitive or restricted scopes for which Google may require security assessment.
BEYOND CHECKLISTS
Why this matters
An OAuth consent screen does not prove application security. Teams need to review permissions, data flows, authentication, vulnerabilities and access lifecycle.

FAQ
Frequently asked questions
Practical distinctions worth understanding before starting your programme.
Does every Google Login application need CASA?
Not automatically. Requirements depend on scopes, requested access and Google's applicable assessment criteria.
Is Google CASA an ISO certification?
No. It is a security assessment programme for certain OAuth applications, not a substitute for ISO standards.
Can we request additional scopes without review?
It depends on permission categories and current Google requirements. Request only necessary access and confirm the verification process.

Framework descriptions are educational. Applicability, service availability and any independent assessment require confirmation for your organisation.
Important scope boundary
ZebraByte can discuss readiness, technical controls and programme management. A regulator, qualified auditor or certification body makes the applicable independent determination. Support for a particular framework is subject to the agreed service scope.
