A startup SBOM policy fits on one page if it covers seven things: scope, format, trigger, storage, sharing, response to new advisories, and ownership. Write only what you do today, date it, and review it twice a year so it matches reality.
Why a written policy helps in sales
When a buyer asks about your SBOM, a one page policy shows the answer is deliberate, not improvised. It also lets any teammate answer consistently. The NIST Secure Software Development Framework frames secure development as a set of practices an organization can adopt in its own way, and a short policy is a simple place to record yours (see Sources).
The seven headings
1. Scope
Which products and services are covered, and which are not yet. Example: "The production API, web app and worker services."
2. Format
The data formats you produce. CISA's 2026 guidance names SPDX and CycloneDX as the two widely used machine-processable formats, so pick one or both and name the version.
3. Trigger
When an SBOM is generated. The guidance says each software version or update should have an associated SBOM, so "on every release build in CI" is a natural trigger. Add that a revised SBOM is issued if errors or new details are found.
4. Storage
Where SBOMs are kept, for how long, and who can read them.
5. Sharing
How you provide them to customers: under what terms, by what channel, and who approves. The guidance says access controls can limit sharing with unauthorized parties but should not block sharing between authorized parties.
6. Response to advisories
Who checks SBOMs when an advisory lands, how you decide whether you are affected, and how you notify customers.
7. Ownership
A named owner, a backup, and a review date.
Sample wording
"This policy covers the SBOMs we produce for our production services. We generate an SBOM in CycloneDX format on every release build and store it with the release record. We share SBOMs with customers on request under our confidentiality terms. When a new advisory affects a component, the security owner checks stored SBOMs, records the result, and notifies affected customers. The owner is the head of engineering, with the CTO as backup. Reviewed April and October."
Rules for keeping it honest
- If you do not do it, do not write it. Put it in a "planned" list with no promises.
- Avoid numbers you do not measure, such as fixed response times.
- Put a date and owner at the top.
- Link to it from your internal runbook so it is used, not filed.
Do not claim more than it is
A policy is not a certification and does not prove the practice works. Describe it as your documented approach. Avoid calling it compliant with any framework unless you have mapped it and can show how.
Review rhythm
Check it twice a year, and after any change in tooling, hosting or product scope. Update the date even when nothing changed, so a reader can see it is alive.
Where Safeguard fits
Safeguard's policies, gates and guardrails let you enforce parts of a policy like this in your pull request flow, and its compliance and evidence automation helps collect records of what ran. See the free scan for a first look.

Look at how a rule blocks or allows a change, which is how a written policy becomes something enforced.
Quick check
Do we need legal review of the policy?
If it will be referenced in contracts, ask your counsel. This post is general guidance, not legal advice.
Can the policy be shared with buyers?
Often yes, and it helps. Remove internal names and anything you would not want a competitor to read.
