NIST SP 800-63-4 provides clear mandate for organizations handling ITAR data to migrate towards an IAL3 implementation strategy, not just as part of compliance checks but rather for national security reasons.

The new version prioritizes stronger, phishing-resistant authentication protocols and emphasizes continuous evaluation of access risk. Furthermore, remote identity proofing and user-controlled wallets (such as mobile driver's licenses or verifiable credentials ) have also been officially introduced into the federation model.

NIST IAL3 verification

NIST 800-63-4 is an essential digital identity management framework, emphasizing extensive identity proofing and strong phishing-resistant authentication. With the final release of NIST SP 800-63A-4, 800-63B-4 and 800-63C-4 in 2025, this standard transitioned from checklist-based requirements to risk-based Digital Identity Risk Management (DIRM).

The new DIRM process enables organizations to dynamically assess threats, service impacts and user populations to determine an ideal Identity Assurance Level (IAL), Authenticator Assurance Level (AAL), and Federation Assurance Level (FAL). NIST 800-63-4 guidelines also mandate more structured and risk-based approaches to CSP assertions to third parties.

Trustswiftly, our comprehensive identity verification platform, assists organizations in meeting IAL2 and IAL3 compliance by using chat, video and facial recognition with liveness detection, document authentication and step-up reproofing based on risk. This provides continuous identity assurance beyond single point-in-time checks while aligning directly with NIST 800-63-3's spirit of reducing attack surface and creating resilient cybersecurity posture.

Trust Swiftly's IAL3 Non-Biometric Pathway allows users to complete nist ial3 verification using only their smartphones, such as taking photos of driver's licenses or other evidence documents. By performing all verifications using mobile phones instead of hardware devices, security risks are reduced significantly.

NIST IAL3 compliance

NIST recently updated its digital identity guidelines in order to assist federal agencies with fulfilling statutory requirements for federated identity management. The updated guidelines differentiate identity proofing, authentication, federation, adaptive risk management through tiered assurance levels as well as eliminating assumptions that certain levels are mandatory; additionally they discourage low assurance methods such as email one-time passwords and SMS two-factor authentication as low-assurance mechanisms.

NIST's new IAL3 process calls for on-site attended identity verification using live sessions with a proofing agent to achieve maximum confidence that claimed identities are authenticated by real world identities. Furthermore, more rigorous evidence validation procedures must also be undertaken, including on-site inspection of physical documents and direct comparison with photo ID's of subjects being proofed; unfortunately this approach limits who can be verified at once and is infeasible with remote proofing solutions.

Fischer Identity offers an innovative Zero Trust solution that can assist organizations in attaining full nist 800-63-4 ial3 compliance. Our advanced identity assurance platform ensures a comprehensive set of processes designed to reduce risks, enable productivity and simplify governance - including automated joiner/mover/leaver workflows, phishing-resistant authenticators and continuous reassessment of user identity, device posture, environmental factors and contextual data.

NIST IAL3 identity verification software

Ial3 identity verification software is the process of verifying that an applicant's identification documents match up with their physical, living existence. This may involve photo comparison, biometric comparison or linking key attributes from evidence with core attributes associated with them - known as SUPERIOR strength identity proofing, this level is often required when performing high-risk transactions such as National Highway Traffic Safety Administration odometer disclosure or IRS accessing tax records.

Proofing level two requires in-person attendance with an on-site CSP representative, who reviews identity documents and directly verifies applicants' physical presence. Furthermore, rigorous evidence validation and biometric binding is conducted for enrollees to help prevent impersonation attacks such as SIM swapping attacks or bypasses to MFA authentication mechanisms. This process ensures biometrics remain securely bound with identity credentials to reduce SIM swapping attacks or MFA bypasses.

The latest edition of the NIST Digital Identity Guidelines emphasizes the need for comprehensive fedramp high identity proofing and secure federated identities. It contains requirements for phishing-resistant MFA/Passkey authentication methods as well as deprecating SMS-based methods of authentication, while advocating cryptographic authenticators, providing guidance on credential creation/maintenance processes, as well as more precise Federated Assurance Levels (FALs) so CSPs may select an FAL suitable to their unique requirements.
