AC.L1-b.1.iv
Control information posted publicly
Anything posted on your public website, social media, marketing collateral, or anywhere accessible to the public must not contain FCI. Have a clear sign-off process so nobody pastes a customer PO into a LinkedIn post or a case study.

“Control information posted or processed on publicly accessible information systems.”

What evidence satisfies this
Any one of these, by itself, won't satisfy the practice — but showing a few of them together is what an assessor or a prime contractor expects to see:
- ✓A one-line policy: "Nothing about a federal contract goes public without owner sign-off."
- ✓A named person responsible for publishing to the company website and social media.
- ✓A pre-publication checklist used before posting case studies or PR.
- ✓Examples of redacted vs original: the SBIR award letter on your About page with dollar amounts redacted, etc.
- ✓A scrubbed list of public pages (website, LinkedIn, Facebook, GitHub) that has been reviewed for accidental FCI exposure.
Common ways small shops fail this
- ✗Posting the SBIR award letter or DoD PO photo to LinkedIn before the agency has cleared it for public release.
- ✗Putting unredacted customer names and dollar amounts in a website case study.
- ✗Marketing pages that quote prime contract language verbatim, exposing flow-down details.
- ✗Open GitHub repos containing scripts that hardcode prime contract numbers or base-access details.
- ✗Press releases drafted by an outside PR firm that lift detail from the award document.
How to fix it in a weekend
- 1Pick one person who has to sign off on anything DoD-related being made public.
- 2Walk your website, LinkedIn, and any GitHub orgs once. Redact or remove anything that surfaces FCI.
- 3Add a one-line "public information" rule to your one-pager.
- 4Set GitHub orgs to private by default for anything touching customer work.
- 5When a prime sends a press release for you to publish, confirm with the contracting officer before posting.
FAQ
Can I say I have a contract with the DoD on my website?+
Generally yes — the existence of a federal contract is public once the award is announced on SAM.gov. What's restricted is everything else: dollar amounts not made public, deliverable details, prime contact info, base-access details, technical approach.
