When a buyer asks "what's your SBOM story," answer in four sentences: how you generate an SBOM, how often, what you can share and under what terms, and what you do when a new vulnerability lands. Keep every sentence true today, offer a sample, and do not promise more than you run.
What the question really means
Nobody expects a seed-stage company to have a mature program. The reviewer wants to know three things: do you know what is inside your software, can you find out fast when a component turns out to be vulnerable, and will you be straight with them about it.
CISA describes an SBOM as an "ingredients list" for software that organizations can use to make more risk-informed decisions (see Sources). Your story is the short account of how you produce and use that list.
The four sentences
Write these once, keep them in a shared doc, and edit the details for each deal.
- How it is made. "We generate an SBOM for each release from our lockfiles and build output in CI, in CycloneDX or SPDX."
- How often. "A new one is produced on every release, and we regenerate when we learn something that corrects an earlier one."
- What you can share. "We can send the SBOM for the version you run, in the format you prefer, under the confidentiality terms in your agreement."
- What happens next. "When an advisory affects a component, we check the SBOM, record whether we are affected, and tell customers who are."
If one of these is not true yet, do not paste it. Replace it with the true version, for example "we generate an SBOM manually each quarter and are moving it into CI."
Why this shape works
The 2026 CISA minimum elements guidance asks that each software version or update has an associated SBOM, and that a revised SBOM be issued when errors or new details come to light. Sentence two mirrors that expectation in plain words. The same guidance says SBOMs should be available promptly to those who need them, with access controls allowed between authorized parties, which is what sentence three describes.
Sentence four matters most to a security reviewer. The guidance notes that organizations with SBOMs can assess new vulnerability information faster, and that VEX statements can help narrow which components are really at risk.
A worked example
Here is a version for a ten-person SaaS company:
"Our CI pipeline produces a CycloneDX SBOM for every tagged release of our API and web app. We keep each one with the release record, and we can send the one for your deployed version under NDA within a few business days. When a new advisory affects a library we use, an engineer checks the SBOM, notes whether the vulnerable code is reachable, and we notify affected customers. We do not yet sign our SBOMs."
That last sentence is deliberate. Saying what you do not do yet reads as credible, and it saves you from an awkward follow-up.
What to attach
- One sample SBOM, ideally from a real release, with internal package names reviewed first.
- A half page describing the process in the four sentences above.
- A named contact for follow-up questions.
Check that your sample is complete enough to stand behind. If a field is unknown, say so explicitly rather than leaving it blank. CISA's guidance asks authors to state whether information is unknown or withheld.
Where Safeguard fits
If you want to produce SBOMs and dependency findings without building the pipeline yourself, Safeguard offers SBOM and dependency scanning, plus reachability analysis to help show which findings matter. You can run a free scan at gold.safeguard.sh/scan.
Quick check
Do I need a signed SBOM to answer this question?
No. A signature is one of the data fields in the 2026 CISA guidance, but a startup can answer honestly that it does not sign yet and say what it plans next.
Should I say we are compliant with the CISA minimum elements?
Be careful. The guidance is not a certification. Say which elements your SBOMs include today, and avoid claiming full alignment unless you have checked every field.
