Kantara Initiative announces the formal publication of the Kantara Initiative International Assurance Program: SP 800-63B-4 Service Assessment Criteria (SAC) & Statement of Criteria Applicability (SoCA), aligned to NIST SP 800-63B Revision 4 – Authentication and Lifecycle Management.
Following completion of the public review process and consideration of community feedback, the assessment criteria have been finalized and are effective immediately.
The published criteria may be requested through the SP 800-63B-4 Service Assessment Criteria webpage by completing the request form.
As of the publication date:
- Authenticator Assurance Level (AAL) assessments can now be conducted against SP 800-63B-4. Initial applications should be submitted to [email protected].
- All organizations seeking assessment and certification are now required to contract directly with Kantara Initiative. Kantara will manage the engagement and assignment of accredited assessors.
