Recent defense contractor remote onboarding activity has exposed a major gap in our national supply chain, necessitating urgent IAL3 implementation as part of an urgent mandate to safeguard national security.

NIST 800-63-4 outlines identity assurance levels (IALs), which indicate how confidently an online identity corresponds with real world identities. Solutions like HYPR that support IAL3 via chat, video, face verification with liveness detection and document authentication help organizations balance business and security objectives while decreasing cyber liability insurance premiums and password reset costs.

NIST IAL3 Verification

NIST 800-63 has recently been updated and now provides for more tailored approaches to nist ial3 verification and authentication. The framework encourages phishing-resistant multi-factor authentication, strengthens requirements against automated attacks on enrollment processes, supports technologies like FIDO passkeys and mobile driver's licenses which facilitate strong identity proofing, authentication and proofing, among other provisions.

NIST SP 800-63-3 offers an essential framework for digital identity management, providing guidance on identity proofing, authentication and secure federated identity practices. With its release in 2025 came an important change: prioritizing stronger authenticators that resist phishing attacks while also including user-controlled verification methods like FIDO passkeys or subscriber wallets as means for user verification.

The updated guidelines also formally define assurance levels (IAL, AAL and FAL) to enable more risk-based Digital Identity Risk Management. This enables relying parties to assess threats and service impacts within their environments before selecting an assurance level suited for them dynamically; also eliminating dependence on single numerical levels as compliance indicators.

NIST IAL3 Compliance

NIST's Digital Identity Guideline, SP 800-63-4, features modernizations to its tripartite framework of IAL, AAL and FAL to better address modern threats like phishing. Furthermore, requirements have been revised to prioritize stronger authentication protocols against attacks by malicious parties.

Nist 800-63-4 ial3 compliance is the strictest level of NIST identity verification and requires an on-site, attended fedramp high identity proofing session with a CSP representative to validate at least one biometric attribute, helping prevent impersonation attacks, SIM swaps and MFA bypasses. It's like having an office security guard reviewing documents against photo IDs for proofing purposes.

Trustswiftly utilizes chat, video, facial recognition with liveness detection and document authentication technologies to achieve NIST IAL3 compliance. The platform supports step-up reproofing based on risk, helping organizations balance business and security objectives to reduce cyber liability insurance and operational costs. HYPR Affirm's central identity system with secure onboarding/offboarding processes supports both compliance levels. This reduces password resets drastically decreasing attack surface.

NIST IAL3 Fedramp

NIST Special Publication 800-63-4 outlines requirements for identity proofing, authentication and federation systems implemented by agencies to meet their business needs in terms of security, user friendliness and scalability. These guidelines help organizations create identity assurance systems which meet these criteria while also meeting agency objectives for effective management.

The fourth version of these guidelines represents a substantial advance, moving away from a single level of assurance and mandating that agencies select between Identity Assurance Level, Authentication Assurance Level and Federated Assurance Level as their level of assurance. Deprecating email OTP and SMS-based authentication directly reflects their high vulnerability to phishing attacks; moreover, this guidance also requires Phish-resistant MFA with both device-bound and syncable authenticators such as FIDO Passkeys as secure authenticators.

Trustswiftly is a FIDO Certified passwordless authentication and ial3 identity verification software designed to help organizations comply with NIST IAL3 guidelines for remote yet supervised authentication with live agents, providing document and biometric comparison with liveness detection for an efficient verification process that reduces cybersecurity liability insurance costs, operational expenses, and man-in-the-middle attacks.

NIST IAL3 High Identity Proofing

NIST SP 800-63-4 IAL3 guidelines offer an updated framework for identity systems with modern requirements for Identity, Authentication and Federation Assurance Levels (IAL, AAL and FAL standards. Their added granularity provides more adaptive risk management by breaking assurance levels into three dimensions - Identity (IAL), Authentication (AAL) and Federation Assurance (FAL).

The NIST 800-63-4 guidelines offer a comprehensive digital identity lifecycle framework, designed to ensure robust identification verification and authentication throughout an employee's digital journey with their organization. In addition, these guidelines address interview fraud prevention strategies, combatting phishing attacks and supporting federated identities as key challenges.

The NIST SP 800-63-4 update significantly downgrades email one-time passwords and SMS-based authentication due to their vulnerabilities to widespread phishing attacks in the workplace. In addition, this revision mandates phishing-resistant MFA with FIDO Passkey support - further solidifying it's position as industry standard strong authentication solution. NIST SP 800-63-4's flexible approach enables Risk Professionals (RPs) to select those xALs most relevant to their business risks instead of following rigid checklist-based framework; claims can also be cryptographically signed between identity providers and RPs using established technical protocols.
