This page lists Kantara Initiative’s various Classes of Approval available to Kantara Credential Service Providers (CSP) members and sets out the Service Assessment Criteria (SAC) applicable to each Class.
CSPs conforming to the applicable sets of SACs (and their related Assessment Profiles, if also applicable) are eligible for a Grant of Approval under the Kantara Trust Operations Program.
Classes of Approval for Identity and Credential Management Systems
(effective 2018-03-21)
Kantara offers a number of Classes of Approval. Each Class is based upon a specific SAC or set of SAC. CSPs may seek Approval of a discrete service in any one or more of these Classes. The following Classes are available to CSPs offering Full or Component credential management services:
| Class of Approval | Description |
| NIST 800-63 rev.3 | Available to Credential Service Providers offering Full or Component credential management services. This Class of Approval is modelled on best practice (drawing from, among other sources, ISO/IEC 27001, ISO/IEC 29115) to ensure the provider organization’s good standing and management / operational practices and criteria which are derived strictly from NIST SP 800-63 rev.3 requirements, that ensure conformant technical provision of the provider organization’s service.
Only Assurance Levels IAL2 and AAL2 are supported at present. |
| NIST 800-63 rev.3 (Technical) | Available to Credential Service Providers offering Full or Component credential management services. This Class of Approval is based on criteria derived strictly from NIST SP 800-63 rev.3 requirements that ensure conformant technical provision of the provider organization’s service.

| Classic | Available to Credential Service Providers offering Full or Component credential management services. This Class of Approval is modelled on best practice (drawing from, among other sources, ISO/IEC 27001, ISO/IEC 29115) to ensure the provider organization’s good standing and management / operational practices and criteria modelled on a genericized interpretation of NIST SP 800-63 rev.2 requirements, that ensure conformant technical provision of the provider organization’s service. Levels of Assurance 1, 2, 3 & 4, as described in OMB M-04-04 |
