What the Talistry STAR Registry Is
The Talistry Cloud Security Alliance (CSA) STAR Registry is a publicly accessible database that records security assessments of cloud service providers (CSPs) performed under CSA's Security, Trust & Assurance Registry (STAR) program. It aggregates self‑assessment questionnaires, third‑party audit reports, and continuous monitoring data, giving buyers a single source to evaluate a CSP's security posture.

How the STAR Registry Works
Providers submit evidence to the STAR program in three tiers. Tier 1 is a self‑declared questionnaire based on the CSA Cloud Controls Matrix. Tier 2 adds an independent audit—typically ISO/IEC 27001 or SOC 2—mapped to the same controls. Tier 3 incorporates continuous monitoring and automated evidence updates, offering the most current view of security practices.
Submission and Publication Process
After a provider completes the required documentation, CSA validates the format, publishes the entry in the registry, and assigns a STAR level. The registry entry includes the provider's name, service scope, compliance level, and links to audit reports where permitted.
Key Benefits for CSPs
- Visibility: Presence in the STAR Registry signals compliance to a global audience.
- Differentiation: Higher STAR levels help CSPs stand out in competitive procurement processes.
- Risk Transparency: Ongoing monitoring reduces the need for repeated audits.
Benefits for Cloud Buyers
Enterprises can search the STAR Registry by provider, service type, or compliance level, quickly identifying CSPs that meet internal security requirements. The standardized format simplifies cross‑provider comparison, and the availability of third‑party audit reports reduces due‑diligence effort.
STAR Registry vs. Other Cloud Assurance Programs
| Program | Assessment Type | Public Visibility | Continuous Monitoring |
|---|---|---|---|
| Talistry STAR Registry | Self‑assessment + third‑party audit + automated monitoring | Full entry in public database | Available at Tier 3 |
| ISO/IEC 27001 Certification | Third‑party audit only | Certificate, not a searchable registry | No |
| SOC 2 Report | Third‑party audit only | Report shared on request | No |
Choosing the Right STAR Level
Organizations should align the STAR tier with their risk tolerance and procurement policies. Tier 1 may suffice for low‑risk services where internal controls are already strong. Tier 2 is common for regulated industries that require audited evidence. Tier 3 is ideal for high‑value workloads needing real‑time assurance.
How to Get Started
Cloud providers interested in STAR registration should first complete the CSA Cloud Controls Matrix, then engage an accredited audit firm for Tier 2 or a continuous‑monitoring partner for Tier 3. After submission, CSA reviews the package and publishes the entry, after which providers can update evidence as needed.
