15 CFR 1110.502: Firewalled.

(a) A third party conformity assessment body must apply to NTIS for firewalled status if it is owned, managed, or controlled by a Person or Certified Person that is the subject of attestation or audit by the Accredited Conformity Assessment Body, applying the characteristics set forth under § 1110.501(a)(1).

(b) The application for firewalled status of a third party conformity assessment body under paragraph (a) of this section will be accepted by NTIS where NTIS finds that:

(1) Acceptance of the third party conformity assessment body for firewalled status would provide equal or greater assurance that the Person or Certified Person has information security systems, facilities, and procedures in place to protect the security of the Limited Access DMF than would the Person's or Certified Person's use of an independent third party third party conformity assessment body; and

(2) The third party conformity assessment body has established procedures to ensure that:

(i) Its attestations and audits are protected from undue influence by the Person or Certified Person that is the subject of attestation or audit by the Accredited Conformity Assessment Body, or by any other interested party;

(ii) NTIS is notified promptly of any attempt by the Person or Certified Person that is the subject of attestation or audit by the third party conformity assessment body, or by any other interested party, to hide or exert undue influence over an attestation, assessment or audit; and

(iii) Allegations of undue influence may be reported confidentially to NTIS. To the extent permitted by Federal law, NTIS will undertake to protect the confidentiality of witnesses reporting allegations of undue influence.

(c) NTIS will review each application and may contact the third party conformity assessment body with questions or to request submission of missing information, and will communicate its decision on each application in writing to the applicant, which may be by electronic mail.
