FedRAMP vs SOC 2 vs ISO 27001: What Transfers?

Side-by-Side

• FedRAMP — US federal cloud authorization on NIST SP 800-53 baselines (Rev 5: Low 156 / Moderate 323 / High 410)
• SOC 2 — CPA attestation against Trust Services Criteria; commercial buyer driven
• ISO 27001 — ISMS certification against Annex A / Statement of Applicability

What Usually Transfers

• Access control, change management, and IR process maturity
• Centralized logging and monitoring programmes
• Vendor risk and policy frameworks (with remapping)

What Does Not Transfer Cleanly

• Federal-specific inheritance, boundary, and customer-responsibility language
• FIPS-validated crypto module proof at FedRAMP depth
• ConMon deliverables and POA&M remediation SLAs expected by AOs
• 3PAO independence rules and FedRAMP package formats

Frequently Asked Questions

Should we do SOC 2 before FedRAMP?

Often yes for commercial pipeline and discipline — but sequence against federal deal timing and the June 11, 2027 Rev 5 new-cert cutoff if applicable.

Does ISO 27001 equal Moderate FedRAMP?

No. ISO certifies an ISMS; FedRAMP authorizes a cloud service against a federal baseline via 3PAO assessment.

Can one platform cover all three?

Shared evidence helps. CyberSilo maps controls once and routes artefacts to the framework that needs them.
