Unlock complete nist 800-63-4 ial3 compliance with a modern identity platform that simplifies compliance and facilitates continuous verification. A Zero Trust architecture transforms compliance requirements into a practical framework that reduces fraud, mitigates risk, and provides secure yet seamless user access for an enhanced user experience.
To meet NIST 800-63-4, your identity management solution must include support for multiple assurance levels--from antiphishing-resistant multifactor authentication journeys and hardware-anchored authenticators for AAL2 assurance levels, through remote and in-person identity proofing at IAL3 assurance levels. Trust Swiftly delivers this functionality all in one package.
Verification
NIST SP 800-63-4 marks an important move from checklist-based requirements to risk-based Digital Identity Risk Management framework, mandating continuous evaluation metrics, new fraud controls and hardware-anchored IAL3.
NIST guidance outlines a tiered approach to assurance levels, enabling RPs to select the level of verification they need for any given transaction. Attented identity proofing requires on-site proofing which includes verifying documents and direct interaction with applicants to establish that they are who they claim they are; this ensures the highest degree of confidence that an individual is who they claim they are while also mitigating highly scalable attacks such as fake resumes with AI capabilities, realistic images or voice clones used for remote technical jobs.
Mitek's solution for validating IAL3 credentials utilizes cryptographic NFC hardware to read the secure chip found on modern e-Passports and driver's licenses, thus verifying their authenticity against live images, thus preventing document forgery as well as phishing and injection attacks. Once verified, Mitek binds credential to subscribers accounts with either strong or superior binding strength - all within just a minute!
Compliance
No matter your role - from federal contractors handling classified data to remote workers safeguarding defense supply chains - NIST 800-63-4 guidelines have strict ial3 identity verification software requirements that must meet. They reframe identity management with a modular framework of Identity Assurance Level (IAL), Authenticator Assurance Level (AAL), and Federation Assurance Level (FAL).
FALs are created to measure the confidence in an authentication assertion from one CSP to a relying party, by tracking every path taken during identity verification at each AAL (such as using MFA or hardware authenticators like PIV/CAC cards).
The new NIST 800-63-4 guidelines send a clear signal that legacy security methods like knowledge-based authentication and SMS-based OTPs are no longer adequate defenses against attacks from hackers, SIM swappers and social engineers. Instead, hardware-anchored IAL3 provides the most defensible identity process to safeguard high risk access while decreasing fraud among remote workforce workers.
High Identity Proofing
The NIST Digital Identity Guidelines set standards for robust nist ial3 verification. The guidelines outline three levels of assurance - Identity Assurance Level (IAL), Authentication Assurance Level (AAL) and Federation Assurance Level (FAL). IAL1, the lowest level, requires no proofing at all; IAL2 mandates moderate verification such as in-person checks or via trusted sources like official documents; while IAL3 demands high authentication methods like hardware-anchored methods like FIDO Passkeys or supervised forensic proofing.
The 2025 final version of SP 800-63-4 moves away from checklist-based requirements in favor of risk-based assessment and stronger, phishing-resistant authentication protocols, making IAL3 implementation not just an administrative task to check off but an imperative strategy to meet. Mobile driver's licenses and verifiable credentials which reduce onboarding friction while increasing assurance levels offer organizations looking to comply with new requirements without impacting user experience; moreover, its requirements specifically call for phishing-resistant multifactor authentication (MFA), further solidifying MFA technologies like FIDO Passkeys within MFA framework.
Trust Swiftly's FedRAMP-align IAL3 Supervised Remote fedramp high identity proofing solution creates an unbreakable cryptographic chain of trust by moving verification events away from mobile devices onto tamper-evident hardware verification events - dramatically altering security equation.
Trust Swiftly's NFC hardware cryptographically verifies the secure chip embedded within modern e-Passports and mobile driver's licenses, eliminating presentation attacks such as silicone masks and high-resolution screens that typically defeat software-only solutions.Interested in ial3 compliance?
