Send the checklist once
Choose the assurance checklist, define the scope, and request a point-in-time response from a vendor, supplier, or B2B partner.
B2B assurance exchange
Request security checklists once. Reuse structured responses across business relationships.
PostureKit helps companies request, complete, snapshot, and share industry-standard security questionnaires such as NIST 800-171. It records a point-in-time response from vendors and partners without pretending to guarantee completion or certification.

Assurance workflow
A cleaner path for security questionnaire exchange.
The platform separates a business request from the vendor response, then preserves that response as a reusable, scoped assurance record.
Complete structured answers
Vendors answer controls, add assurance commentary, and reference evidence without uploading sensitive artefacts into the platform.
Share the same response again
Businesses keep a reusable response record that can be shared with future requestors without redoing the checklist every time.
Response reuse
Vendors should not rebuild the same assurance packet every week.
PostureKit lets a responding business keep a structured answer set with scope, status, reviewer notes, confidence, and review dates. The next request can reuse the same response where the scope still applies.
Requesting businesses get clearer state tracking: requested, in-review, responded, declined, expired, or superseded. That means procurement and security teams can see what they actually have, not what they hoped would arrive.
Trust model
Designed to preserve judgement, scope, and uncertainty.
PostureKit does not certify companies, guarantee that a vendor will respond, or claim that a response remains valid forever. It captures what was asserted, by whom, for which scope, and at what point in time, so businesses can make better assurance decisions.
