NIST 800-63-4 IAL3 Digital Identity Guidelines issued in 2025 marked an important strategic shift, emphasizing phishing-resistant authentication and robust federated identities. HYPR Affirm, our comprehensive nist ial3 verification platform, meets these new requirements by supporting both IAL2 and IAL3 through chat, video, facial recognition with liveness detection capability, document authentication and step-up reproofing that is activated based on risk.

Compliance Fedramp

Cloud service providers (CSPs) wishing to work with federal agencies must adhere to the Federal Risk Management Act, which mandates CSPs implement security protocols to protect sensitive data while adhering to NIST SP 800-63-4 guidelines.

These guidelines classify information according to its impact using NIST FIPS 199 security categorization, categorizing each level according to Low, Moderate or High impact levels. Each level requires various security measures with more stringent security controls being necessary at higher impact levels. By visiting this page, you can rapidly understand Nist Ial3 Verification.

The new ial3 identity verification software also offer more flexibility in terms of identity proofing. Instead of mandating that all authenticators use identical levels of assurance, the guidelines allow CSPs to select different IAL and AAL levels based on their specific business needs.

Additionally, these guidelines offer several preparatory documents and templates to aid your nist 800-63-4 ial3 compliance efforts. Third-party assessors can be hired to monitor progress. You should document any gaps in your security protocol that cannot be resolved immediately as well as set a schedule to revisit these areas in the future.

High Identity Proofing

NIST SP 800-63-4 outlines new security and compliance requirements that demand high assurance authentication, moving away from checklist-based identity standards towards risk-based Digital Identity Risk Management (DIRM). This framework emphasizes dynamic risk decisions according to context and mission impact for every transaction.

These new standards redefine identity assurance to include multiple levels - Identity Assurance Level (IAL), Authenticator Assurance Levels (AAL), Federation Assurance Levels (FAL), as well as Federation Service Provider (IdP).

The new standards disfavor SMS OTP and significantly downgrade email OTP in AAL2, and mandate phishing-resistant methods like FIDO Passkeys to meet AAL3 identity assurance. Implementing an identity fraud mitigation and risk management solution designed specifically to align with these new standards not only protects your business but also minimizes user friction so your customers can safely utilize your services without altering their behavior.

Easy to Implement

Many existing workflows, such as knowledge-based authentication and SMS one-time passcodes, run the risk of not meeting SP 800-63-4 IAL3 thresholds due to social engineering attacks and are therefore at risk. In fact, these may no longer meet even IAL1 requirements. By mandating on-site proofing and biometric collection at fedramp high identity proofing centers, IAL3 limits highly scalable attacks while protecting against synthetic and compromised identities. Enhancing phishing resistance through new authenticator options that are resistant to phishing attacks, the bill also mandates CSPs to create subscriber accounts during enrollment and associate CSP-issued or subscriber-provided authenticators with them - this information can be found both normative and informative within [SP800-63A].
