Regulators should move toward outcome based rules, mutual recognition, and clearer coordination across departments. When one technology has already been tested and accepted in one regulatory context, other bodies should be able to recognise that evidence within a reasonable timeframe. That approach reduces duplicate assessments, lowers cost for businesses, and makes it easier for safe technologies to scale without waiting years for separate approvals.
What consistent approval should look like for new identity technologies
Consistent approval does not mean one central office rubber stamps every product or protocol. It means regulators judge the same underlying security properties in the same way, so a technology that already met those requirements in one setting can be reused elsewhere without restarting the process from zero. For identity systems, that usually means clear criteria for assurance, interoperability, auditability, and operational controls.
A regulator that wants consistency should start by defining the outcome it is trying to verify: whether the technology can identify, authenticate, authorise, and recover safely in a real deployment. That is the right level of abstraction for new schemes because the implementation details may change, but the trust question does not. Consistency comes from stable tests, not from forcing every department to use the same product or architecture.
Regulatory consistency also depends on evidence portability. If a technology has already been reviewed against a serious control set, the next authority should be able to accept that record unless there is a material local difference, such as a different threat model, legal basis, or operational context. Mutual recognition is most useful when it is bounded by clear criteria for equivalence, so approvals are faster without becoming weaker.
Why fragmentation slows safe identity innovation
When departments each invent their own approval criteria, vendors face duplicate questionnaires, repeated security testing, and inconsistent interpretations of the same risk. That creates delay for legitimate products and raises the cost of compliance without necessarily improving safety. It also makes it harder for smaller innovators to enter regulated markets because the approval burden grows with each new jurisdiction or agency.
Fragmentation has a second problem: it can distort incentives. Teams end up designing to the quirks of a particular approval path instead of to durable security requirements. In identity technologies, that can produce over-specific controls, narrow integrations, or documentation that satisfies one reviewer but does not travel well to the next. The result is slower adoption, not better assurance.
The other issue is that regulators may unintentionally create an uneven trust landscape. A technology accepted in one department may be treated as unfamiliar in another, even when the underlying evidence is the same. That is why coordination across agencies matters, especially where the same identity evidence, standards, or assurance artefacts can be reused across multiple review bodies. For identity-specific governance and lifecycle controls, the regulatory and audit perspectives in NHIMG’s Ultimate Guide to NHIs are useful for understanding how approval evidence can be made reusable across control environments.
How regulators can make approval more consistent in practice
The most effective approach is to separate policy from implementation. Regulators should publish outcome based rules that describe what good looks like, then accept multiple technical designs that meet the same bar. They should also publish common evidence templates so applicants know what proof is needed on assurance, logging, incident response, identity proofing, and ongoing monitoring.
Shared recognition frameworks are especially valuable when paired with clear escalation rules. If a technology has been approved elsewhere, the receiving authority should confirm whether the prior assessment is still current, whether the deployment context is materially different, and whether any new risk has emerged. That keeps recognition from becoming blind repetition while still avoiding full rework. The standards section in NHIMG’s Ultimate Guide to NHIs is a practical reference point for the kinds of control families regulators often expect to see aligned across approvals.
Regulators should also publish internal coordination rules. If one department has already assessed a technology, other departments should know how to reuse that assessment, who can challenge it, and how quickly a final decision must be made. Without that operating model, mutual recognition stays theoretical and approval delays remain high. Where identity technologies rely on signed assertions, federation, or token-based trust, alignment with external standards such as NIST SP 800-63 Digital Identity Guidelines and OpenID Connect Core 1.0 can help make the assurance basis more legible across authorities.
Risk and Threat Considerations
Inconsistent approval creates a security and market risk at the same time. It can slow down safe technologies, but it can also let low-quality reviews stand in for real assurance if regulators treat prior approval as a shortcut rather than a transferable evidence base. The challenge is to avoid both extremes: duplicated bureaucracy on one side and unexamined trust on the other.
Failure mechanism: Authorities may accept or reject technologies based on local process variation instead of the actual assurance properties, which leads to duplicated effort, gaps in review, and uneven treatment of the same risk.
Impact: Safe identity technologies take longer to reach production, while weak ones may be overtrusted in one context and under-scrutinised in another, increasing exposure for both users and regulators.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-63, OWASP ASVS, NIST CSF 2.0 and NIST SP 800-53 Rev 5 set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-63 | Digital Identity Guidelines | Directly governs identity assurance, authentication, and federation consistency across approvals. |
| Recommendation — Align approval criteria to identity assurance levels and accepted federation evidence. | ||
| OWASP ASVS | V10 — OAuth and OIDC | Identity technologies often rely on federated login and token standards that need consistent review. |
| Recommendation — Use V10 to evaluate token and federation implementations against a shared baseline. | ||
| NIST CSF 2.0 | GV.PO-01 — Policy established, communicated and monitored | Approval consistency depends on clear policy and repeatable governance across departments. |
| Recommendation — Publish a common approval policy and monitor it for consistent application. | ||
| ISO/IEC 27001:2022 | A.5.15 — Access control | Identity tech approvals must verify access governance and authorization principles. |
| Recommendation — Require access-control evidence as part of every technology approval. | ||
| NIST SP 800-53 Rev 5 | IA-2 — Identification and Authentication (Organizational Users) | Identity technologies must be assessed for authentication assurance and control consistency. |
| Recommendation — Test whether the technology meets the required identification and authentication assurance. | ||
Practitioner Guidance
What to prioritise: Define a small set of approval criteria that every department must use, then require applicants to map their evidence to those criteria rather than to the habits of a single reviewer. That gives you consistency without forcing identical implementation.
What to verify: Before reusing an earlier approval, verify that the previous assessment covered the same assurance level, threat model, and deployment context. If any of those differ materially, treat the case as a new review rather than a recognition exercise.
Practitioner takeaway: The real test of regulatory consistency is whether a safe technology can carry its evidence across approval bodies without losing meaning, not whether every body uses the same paperwork.
