SCITT vs SBOM: how they differ, side by side
How SCITT and SBOM differ: what each is, who owes it, when it applies and who enforces it.
01 / Side by side
SCITT and SBOM, side by side
| SCITT | SBOM | |
|---|---|---|
| What it is | technical specification | guidance |
| Jurisdiction | International | United States (federal) |
| Legal force | Voluntary standard | Guidance; binding only where a contract or sector rule requires it |
| Status | Published standard | Published standard |
| Applies from | June 2026 | 12 Jul 2021 |
| Who owes it | Issuers of supply chain statements (e.g. software producers, auditors), operators of transparency services, and relying parties that verify them. | Software producers selling to federal agencies or regulated buyers, and organizations that procure or operate software. |
| Enforcement | None; voluntary. | No general penalty. Federal agencies may require SBOMs by contract (OMB M-26-05); other mandates come from sector rules and foreign law. |
02 / SCITT
What SCITT requires
Any statement about an AI artifact, such as a model card, evaluation result or dataset hash, can be registered and receipted. The RFC targets software supply chains and does not address AI specifically.
- 01Issuers sign statements as COSE_Sign1 messages about a specific artifact.
- 02Transparency services keep an append-only, non-equivocating log that cannot modify, delete or reorder entries.
- 03Transparency services publish and apply a registration policy, itself recorded on the log.
- 04Transparency services register a statement before releasing its COSE receipt (RFC 9942).
- 05Relying parties and auditors verify receipts and log consistency rather than trusting the operator.
03 / SBOM
What SBOM requires
The 2026 baseline expressly covers AI software but adds no AI-specific fields; CISA and G7 partners issued separate AI SBOM minimum elements in May 2026 as a supplement.
- 01Produce SBOMs with the 17 minimum data fields, including component producer, version, identifiers, hash value and license.
- 02Record SBOM author, timestamp, tool name and version, and generation context (lifecycle phase).
- 03Sign the SBOM so recipients can confirm it is unaltered (SBOM Author Signature).
- 04Use machine-processable formats such as SPDX or CycloneDX and update the SBOM when components change.
- 05For federal cloud contracts with SBOM terms, provide an SBOM of the runtime production environment on request.
Optional evidence · where Planisphere fits
Keep a record anyone can check
When your team meets a duty, Planisphere can seal the event it reports as a receipt.
A disclosure shown, a review signed, a model change approved: the event your system reports.
The event becomes a sealed receipt, dated and attributed to whoever is signed in.
Paste the receipt into Verify. No account or key.
A record supports your compliance evidence process. It is not a legal finding or a certification. Systems that call Planisphere's gate API can also hold or refuse an action before it runs.
