GSS One Authenticated Trust Center
Certification information that is easier to evaluate, access, and reuse.
Review public service context, understand how protected FedRAMP certification information is shared, authenticate with your existing identity, and request human or programmatic access when needed.

You can sign in without selecting a CSO. A CSO-specific public link preserves the correct package context through authentication without granting entitlement.
How protected access works
Authentication tells the portal who you are. Authorization is a separate live decision in PHSEnt. The portal never treats a local request record as package permission.
Authenticate
Use the identity provider appropriate for your organization.
Check entitlement
PHSEnt is checked immediately for current ViewCsoData authorization.
Request if needed
If you are not already entitled, submit the controlled access request and track its status.
Use or integrate
Authorized users can browse/download packages and request read-only programmatic API access.
Secure sign-in
Authenticate with your existing identity
Choose the provider appropriate for your organization. Signing in alone never grants access to protected certification data.
Find the path that matches your role
Persona guidance explains what each audience can accomplish without changing the underlying authorization boundary.
Agencies
Evaluate services, obtain certification information, understand reuse, and access protected packages or APIs.
FedRAMP
Reach certification information, OCRs, quarterly reviews, feedback, and authorized access-history reporting.
Assessors
Navigate current and historical certification evidence through structured package views rather than a raw folder tree.
CSO / CSP
Explain trust, certification sharing, reuse, and sales value while keeping authorization and protected package storage authoritative.
