NIST SP 800-63-4 provides a core framework for digital identity, with separate assurance levels for identity proofing, authentication and federated identity management. Furthermore, this standard updates requirements to create a more adaptive risk management process.

For higher assurance levels, these guidelines recommend using phishing-resistant methods like FIDO Passkeys that provide greater assurance, fully recognize remote fedramp high identity proofing processes, and offer more flexible approaches to managing individual identifiers by permitting dynamic control over them.

Authentication

NIST 800-63-4 redefines identity assurance by shifting away from checklist-based requirements and towards risk-based Digital Identity Risk Management (DIRM) framework. This shift emphasizes strong phishing-resistant authentication protocols while simultaneously requiring organizations to assess threats, service impacts and user populations before selecting an Identity Assurance Level (IAL), Authenticator Assurance Level (AAL), or Federation Assurance Level (FAL).

Fischer Identity provides you with the confidence to meet these changes head on with our comprehensive IAM platform, tailored for workforce identity proofing across employee lifecycle stages. Our HYPR Affirm solution supports NIST compliance through chat, video, facial recognition with liveness detection, document verification and step-up reproofing based on risk - not only fulfilling NIST requirements but also significantly reducing cyber liability insurance costs and operational expenses from password resets while offering secure seamless access to apps and data - not forgetting standards-compliant assertion handling via SAML 2.0 or OIDC for federated identities.

Compliance

Although many IAM vendors rush to update their products to comply with NIST 800-63-4, Fischer Identity's Zero Trust architecture was specifically created to meet these modern assurance requirements. Our zero-trust architecture provides continuous reassessments of user identities, device posture and environmental factors as part of its "never trust, always verify" mandate set out by NIST 800-63-4.

NIST 800-63-4's modernization represents a revolutionary change to digital identity management: an evolving modular framework of IAL, AAL and FAL that makes compliance part of daily reality rather than an annual checkbox exercise. Fischer Identity's solutions enable full compliance with this paradigm through dynamic MFA orchestration, PIV/CAC cards as authenticators, SAML 2.0 authentication service (OIDC encryption for FAL1) and high level privacy for FAL2 services.

Fischer Identity's automation tools facilitate joiner/mover/leaver workflows that balance strong security with easy onboarding for employees, students, contractors, volunteers and more - thus reducing insider threat exposure while simultaneously improving user experience.

Fedramp

Fischer Identity's comprehensive IAM platform already delivers all of the processes required for NIST 800-63-4 compliance. Dynamic MFA orchestration supports software-based journeys at AAL2 and hardware authenticators such as PIV/CAC cards at AAL3. Federacy assurance levels are strong, using signed and encrypted assertions compliant with NIST SP 800-63C for strong federation assurance levels and joining/moving/leaving workflows that balance risk with user experience while simplifying governance.

NIST SP 800-63-4 modernizes digital identity management through a three-tier framework of Identity Access Layer (IAL), Authorization Access Layer (AAL), and Federation Authorization Layer (FAL). Trustswiftly makes nist 800-63-4 ial3 compliance alive through continuous and adaptive nist ial3 verification of users, devices and networks - turning compliance into an active security posture that reduces fraud while safeguarding data protection while supporting secure digital services.

High Identity Proofing

Revision 4 of NIST's Special Publication 800-63, Digital Identity Management Guidelines, raises assurance levels in identity proofing, authentication and federation processes to reduce fraud while safeguarding sensitive data and increasing trust within digital interactions.

One key change introduced by SP 800-63-4 is the requirement to link claimed identities to real world identities, so as to reassure RP's that they are dealing with identical people in both environments. Furthermore, linking claims with real identities enables stronger risk assessments when authorizing access over federated assertions.

Fischer Identity provides a comprehensive ial3 identity verification software with automated joiner/mover/leaver workflows and risk scoring that makes lifecycle management and governance simpler, while its FIDO Certified passwordless authentication and biometrics offer up to AAL3 assurance levels while offering flexible user experiences. Furthermore, cryptographic binding in federated transactions and formal user-controlled wallets with verifiable credentials for strengthening FALs provide needed scalability and flexibility that meets federal requirements for an identity ecosystem.
