Classes of Approval

This page lists Kantara Initiative’s various Classes of Approval available to Credential Service Providers (CSPs) and sets out the Service Assessment Criteria (SAC) applicable to each Class, and Service descriptors/Approval types under Kantara’s Identity Assurance Framework scheme.
CSPs conforming to the applicable sets of SAC (and their related Assessment Profiles, if also applicable) are eligible for a Grant of Approval under the Kantara Trust Operations Program.

1. Classes of Approval for Identity Proofing and Credential Management Systems

Kantara offers a variety 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 ApprovalDescription
NIST 800-63 rev.3

Available to Credential Service Providers offering Full or Component credential management services. Modeled on best practice (drawing from, among other sources, ISO/IEC 27001, ISO/IEC 29115), this Class of Approval ensures the provider organization’s good standing and management / operational practices and assesses criteria which are derived strictly from NIST SP 800-63 rev.3 requirements, ensuring a conformant technical provision of the provider organization’s service.

Assurance Levels: IAL2, IAL3;  AAL2, AAL3;  FAL2, FAL3

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. This Class of Approval does not assess the provider organization’s good standing and management/ operational practices; it focuses on the technical provision ONLY.

Assurance Levels: IAL2, IAL3;  AAL2, AAL3;  FAL2, FAL3

Classic

Available to Credential Service Providers offering Full or Component credential management services. Modeled on best practice (drawing from, among other sources, ISO/IEC 27001, ISO/IEC 29115), this Class of Approval ensures the provider organization’s good standing and management / operational practices and assesses criteria modeled on a generalized interpretation of NIST SP 800-63 rev.2 requirements, ensuring conformant technical provision of the provider organization’s service.

Levels of Assurance: 1, 2, 3 & 4, as described in OMB M-04-04

4. Applicable Kantara Service Assessment Criteria sets and Service descriptors/Approval types

The table below gives consistent descriptors to service types and relates each to the sets of SAC against which conformity is assessed and the Classes of Approval which are granted, for each type. Credential Service Providers are required to use one of these service descriptors when describing their service.

Kantara will recognize and approve services as being in one of the following types, according to the choice and degree of scoping of the service with respect to applicable SACs.
