Google CASA & MASA Testing
App security assessment for Google Cloud and Android marketplace
What this engagement covers
The service
Google's Cloud Application Security Assessment (CASA) and Mobile Application Security Assessment (MASA) are required for apps that access Google user data or want to display security badges on the Play Store. Our testing satisfies CASA Tier 2/3 and MASA requirements with authorized lab-quality assessments.
What we test
For CASA, we assess web applications, APIs, and cloud services that integrate with Google APIs and handle Google user data. For MASA, we test Android applications against the OWASP MASVS standard including data storage, cryptography, authentication, network security, platform interaction, and code quality.
Scoping & Assessment Depth
Black Box Assessment
Zero-KnowledgeSimulates an external adversary targeting Google CASA & MASA Testing with no internal credentials, source code, or architecture documentation. Assesses perimeter exposure, unauthenticated attack paths, and edge resilience.
Gray Box Assessment (Recommended)
CredentialedSimulates an authenticated user, tenant, or insider threat within Google CASA & MASA Testing. We evaluate role segregation, authorization boundaries, privilege escalation, and business logic flaws across user tiers.
White Box / Source-Assisted
Full-KnowledgeConducted with direct access to architecture schematics, configuration files, and API/code documentation. Eliminates blind spots and provides exhaustive coverage of security mechanisms governing Google CASA & MASA Testing.
Attack Surface & Vulnerability Vectors
Insecure Local Data Storage
Rigorous testing and validation to uncover Insecure Local Data Storage across your Google CASA & MASA Testing environment. We produce deterministic proof-of-concept exploits to verify exploitability without risking service stability.
Missing Certificate Pinning
Rigorous testing and validation to uncover Missing Certificate Pinning across your Google CASA & MASA Testing environment. We produce deterministic proof-of-concept exploits to verify exploitability without risking service stability.
Hardcoded API Keys or Secrets
Rigorous testing and validation to uncover Hardcoded API Keys or Secrets across your Google CASA & MASA Testing environment. We produce deterministic proof-of-concept exploits to verify exploitability without risking service stability.
Insufficient OAuth Scope Validation
Rigorous testing and validation to uncover Insufficient OAuth Scope Validation across your Google CASA & MASA Testing environment. We produce deterministic proof-of-concept exploits to verify exploitability without risking service stability.
Improper WebView Configuration
Rigorous testing and validation to uncover Improper WebView Configuration across your Google CASA & MASA Testing environment. We produce deterministic proof-of-concept exploits to verify exploitability without risking service stability.
Missing Root/Jailbreak Detection
Rigorous testing and validation to uncover Missing Root/Jailbreak Detection across your Google CASA & MASA Testing environment. We produce deterministic proof-of-concept exploits to verify exploitability without risking service stability.
How we run it
Our CASA assessments follow the App Defense Alliance (ADA) methodology, testing against OWASP ASVS Level 1/2 requirements. MASA assessments follow OWASP MASVS and MSTG procedures. We provide detailed findings reports compatible with Google's submission requirements and work directly with the ADA process.
Application scope and data flow analysis
Rigorous technical execution, boundary verification, and manual exploitation testing targeting application scope and data flow analysis across your google casa & masa testing deployment.
OWASP ASVS/MASVS control testing
Rigorous technical execution, boundary verification, and manual exploitation testing targeting owasp asvs/masvs control testing across your google casa & masa testing deployment.
Authentication and session management testing
Rigorous technical execution, boundary verification, and manual exploitation testing targeting authentication and session management testing across your google casa & masa testing deployment.
Data storage and privacy assessment
Rigorous technical execution, boundary verification, and manual exploitation testing targeting data storage and privacy assessment across your google casa & masa testing deployment.
Cryptographic implementation review
Rigorous technical execution, boundary verification, and manual exploitation testing targeting cryptographic implementation review across your google casa & masa testing deployment.
API and network security testing
Rigorous technical execution, boundary verification, and manual exploitation testing targeting api and network security testing across your google casa & masa testing deployment.
Platform-specific security testing (Android/Cloud)
Rigorous technical execution, boundary verification, and manual exploitation testing targeting platform-specific security testing (android/cloud) across your google casa & masa testing deployment.
Google ADA submission documentation
Rigorous technical execution, boundary verification, and manual exploitation testing targeting google ada submission documentation across your google casa & masa testing deployment.
What you receive
Findings land in your tracker as you go, not only in a PDF at the end. Retest is in scope, not a change order.
- CASA/MASA compliant security assessment report
- OWASP ASVS or MASVS compliance mapping
- Vulnerability findings with evidence
- Google submission-ready documentation
- API security assessment results
- Data handling and privacy evaluation
- Remediation guidance for identified issues
- Retest validation report for resubmission
What we usually find
The issues this engagement surfaces most often. Yours will differ, but this is the shape of it.
Who this is for
Auditor-Ready Compliance Crosswalk
| Framework | Control Section | Testing Evidence & Report Deliverable |
|---|---|---|
| OWASP MASVS / MSTG | MASVS-STORAGE, CRYPTO, AUTH | Comprehensive mobile security verification across client storage, reverse engineering protection, and backend communications. |
Findings are mapped to Google CASA, Google MASA, OWASP ASVS, OWASP MASVS, so the report drops into an audit package rather than needing to be translated first. If you need the readiness work behind one of those, that is a separate engagement.
Frequently Asked Questions
Direct answers on scoping, methodology, compliance validation, and deliverables.
Our Google CASA & MASA Testing service combines deep manual testing with automated verification. We cover: CASA/MASA compliant security assessment report, OWASP ASVS or MASVS compliance mapping, Vulnerability findings with evidence, Google submission-ready documentation, API security assessment results. Every engagement includes reproducible proof-of-concept exploits, developer-ready remediation guidance, and a free retest.
Yes. Findings are directly mapped to Google CASA, Google MASA, OWASP ASVS, OWASP MASVS control requirements. The resulting report is auditor-ready and formatted for immediate submission to SOC 2 CPAs, PCI QSAs, and enterprise vendor risk assessment teams.
Yes. Every Lorikeet Security engagement includes free retesting within 30 to 60 days to validate that your remediation patches successfully resolve the identified vulnerabilities before your final report is issued.
Typical active testing turnaround is 1-2 weeks, with critical findings reported immediately via your Talon portal so your engineering team can begin remediation without waiting for the final PDF.
Pricing starts from $7,500. We scope the engagement in one call based on your environment's surface area, user roles, and complexity, providing a transparent, fixed-price quote with no hidden change orders.
