We’ve got important news for all Google Workspace Admins:
We’re proud to share that GAT+, our flagship auditing and management tool for Google Workspace, has officially achieved CASA Tier 3 certification, the highest level of security accreditation offered by Google.
This badge is now live on our Google Workspace Marketplace listing, and it signals one thing clearly:
GAT+ meets the strictest security standards for third-party tools integrated with Google Workspace.
What is CASA Tier 3?
The Cloud Application Security Assessment (CASA) is Google’s benchmark framework for evaluating the application-layer security of third-party apps that integrate with its ecosystem.
Google assigns Tier 3 to tools like GAT+ that access and manage sensitive organizational data.
Here’s how it works:
- ▪️Tiered Approach: CASA applies different security requirements based on the criticality of an app’s data access. Tier 3 is the most comprehensive.
- ▪️ Independent Audit: Google certified experts review the app’s security architecture, policies, and practices.
- ▪️ Industry Standards: CASA follows OWASP’s Application Security Verification Standard (ASVS) to ensure consistency across all vendors.
In short, CASA Tier 3 proves that GAT+ meets Google’s highest expectations for application security.
