WHAT IS CASA Industry-Recognized Cloud Security Standard CASA is the security validation framework developed by the App Defense Alliance - ensuring applications that access user data meet the highest standards of data protection and privacy across the broader app ecosystem.
Data Security Validation CASA validates that cloud applications - from mobile to serverless - securely integrate with cloud and local storage systems. The assessment ensures consumer data is protected against unauthorized access, data leakage, and evolving threat vectors across the entire app ecosystem.
Transparency & Consumer Trust By undergoing a CASA assessment, applications demonstrate the highest standard of transparency and control over data security and privacy. The assessment identifies vulnerabilities before they can be exploited, strengthening consumer trust and vendor credibility across the ecosystem.
Risk-Based Tiered Evaluation CASA employs a flexible, tiered evaluation process - ensuring security measures are proportional to the specific risks and data sensitivity of each application. Tier 2 lab assessments conducted by authorized labs like NetSentries provide the most rigorous level of independent validation.
Comprehensive Coverage From mobile applications and web platforms to serverless architectures and API integrations - CASA covers the full spectrum of cloud application types, verifying the security posture of every integration point that processes or stores user data.

CASA TIERING
Three Tiers of Assurance
CASA recognizes three tiers of assessment for cloud applications. All requirements must be satisfied for every tier - the difference is the assessment method. The higher the tier, the higher the confidence in security compliance. All applications must be revalidated annually.
TIER 1
Self-Assessment
LOW RISK PROFILE
Reserved for applications with very low risk profiles as determined by the ADA. Teams use CASA-recommended scanning tools to check their applications for common vulnerabilities independently.
Self-scan using recommended tools
Low-risk data access applications
Annual revalidation required
NETSENTRIES AUTHORIZED
TIER 2
Lab Verified
DEVELOPER TESTED • LAB VALIDATED
Developers scan their application and provide results alongside evidence to an authorized lab like NetSentries for verification. The lab validates compliance and issues a Letter of Validation - without needing access to application code or infrastructure.
73 CASA requirements (OWASP ASVS 4.0)
Letter of Validation from authorized lab
No code or infrastructure access needed
Enables access to sensitive API scopes
TIER 3
Full Lab Assessment
LAB TESTED • LAB VERIFIED
The most comprehensive tier - the authorized lab independently tests and validates the application's security. Required for high-risk applications and available for self-initiated assessments seeking the highest level of assurance.
Full independent lab testing & validation
High-risk profile applications

Available for self-initiated assessments
How Tiers Are Determined
Tiers are calculated by the ADA framework partners - not the application developer. The required tier is determined based on data sensitivity, user volume, risk tolerance, and external risk indicators. Applications must pass all 73 CASA requirements regardless of tier.

ASSESSMENT PROCESS
How a CASA
Assessment Works
A structured, transparent process - from notification through validation - ensuring your application meets every CASA requirement with expert guidance at each stage.
01
Notification & Scoping
An ADA partner (e.g., Google) notifies the applicant that their application is in scope for a Tier 2 CASA assessment. Scope, timelines, and requirements are established.
02
Lab Assessment
NetSentries conducts the Tier 2 assessment in our authorized laboratory - evaluating the application against OWASP ASVS requirements mapped to CASA's security controls.
03
Remediation Guidance
If any CASA requirements are not met, NetSentries provides detailed remediation guidance - enabling your team to address findings and achieve compliance efficiently.
04
Validation & Certification
Once all CASA requirements are met, NetSentries issues formal validation - confirming the application has passed the CASA assessment and can operate securely within the ecosystem.
STANDARDS & FRAMEWORK
Built on OWASP ASVS
CASA is grounded in the OWASP Application Security Verification Standard - the
most widely adopted framework for defining application security requirements.
Rigorous, Framework-Aligned Testing
The assessment evaluates cloud and local storage integrations through risk-based tiers derived from OWASP ASVS. This ensures every application is tested against globally recognized security benchmarks - not arbitrary checklists - covering authentication, session management, access control, cryptography, and data protection.
