Trustswiftly helps agencies meet this stringent requirement easily using FIDO certified passwordless authentication kiosks that use biometric verification technology for document authentication. Trustswiftly’s authentication service meets this strict standard easily and helps agencies comply with it efficiently.
NIST SP 800-63-4 represents an impressive modernization of digital identity guidelines, shifting away from checklist-based requirements and towards risk-based Digital Identity Risk Management framework with adaptive context-aware verification and Zero Trust alignment.
NIST 800-63-4 IAL3 Verification
The latest version of NIST’s Digital Identity guidelines provides a robust framework for fedramp high identity proofing, authentication, and federated identity management. The new guidance significantly enhances measures to fight cyber fraud by repurposing IAL1 as a new assurance level, updating authentication risk and threat models, mandating phishing-resistant MFA for AAL2 and higher, integrating FIDO Passkeys into those requirements, and introducing subscriber-controlled wallets like mobile driver’s licenses and verifiable credentials.
A key update is a shift in the threat model and a call for independently tested defenses against injection-based attacks like impostor attack presentations (IAPARs). NIST’s reliance on CEN TS 18099 as a third-party test standard to verify that a solution offers protection against injection threats is especially significant, as it ensures that defenses against these kinds of attacks are actually implemented and working as intended.
The new guidelines also require a level of flexibility, officially allowing for remote identity proofing at AAL2. This allows CSPs to support users with diverse, innovative options that can reduce onboarding friction while still complying with IAL2 requirements.
NIST 800-63-4 IAL3 Compliance
NIST 800-63-4 is the 2025 update to the Digital Identity Guidelines, providing identity assurance through three modular levels: identity proofing (IAL), authenticator assurance level (AAL) and federation assurance level (FAL). This updated standard strengthens security and user experience through rigorous identity proofing practices, robust phishing-resistant authentication methods and secure federated identity practices. While many Identity Access Management vendors rush to meet compliance standards quickly, Fischer Identity’s products have always aligned themselves to them from day one.
Significant modifications pertain to AAL, where NIST now explicitly permits phishing-resistant FIDO passkeys as part of AAL2 and AAL3 levels of authentication. Furthermore, subscriber wallets — such as verifiable credentials or mobile driver’s licenses — have been added into federation models under these new standards.
Additionally, AAL3 now goes beyond simple point-in-time checks to continuously validate identity using methods such as chat, video, facial recognition with liveness detection, document authentication and document authentication. The result is a more robust verification process which reduces risk and lowers cyber liability insurance costs while eliminating password resets and other costly help desk expenses.
Fischer Identity supports AAL3 through an all-encompassing digital identity and authentication solution that includes Zero Trust architecture – providing constant context-aware verification of users and devices across an enterprise, in order to prevent attacks from penetrating its perimeter by employing a “never trust, always verify” policy that identifies and verifies trusted connections.
NIST 800-63-4 IAL3 Identity Verification Software
NIST (National Institute of Standards and Technology), better known by its acronym NIST, serves as an industry benchmark in many business, science, and technology disciplines. Their standards can be used as yardsticks for comparison or alignment by organizations; nist ial3 verification and authentication are two key applications of these standards.
Authentication refers to the process of correlating claimed identities with their real-world counterparts, while identity verification establishes how confidently an individual can assert they are who they claim they are. NIST offers three assurance levels – AAL1 through AAL3 – in order to help organizations map identities and authentication workflows against risk thresholds.
An effective nist 800-63-4 ial3 compliance strategy demands a modern identity platform capable of supporting a range of authentication options across all AALs – AAL1 doesn’t need any linkage with real world identities, while AAL3 requires hardware-anchored phishing-resistant MFA and biometric authentication mechanisms like Fischer. Furthermore, its powerful federation engine supports SAML 2.0 assertions as well as OIDC assertions for full compliance.
Our AAL3 solution also supports advanced PAD capabilities like dynamic liveness verification – verifying whether or not the person being authenticated is actually present on their device or webcam – along with science-based face verification from iProov certified for zero impostor attack presentation acceptance rate (IAPAR) and passing CEN TS 18099 standard for injection attack detection.
FedRAMP High Identity Proofing
NIST Special Publication 800-63-4 provides federal agencies with guidelines for identity verification that allow them to reliably ascertain a user’s real-world identity and trustworthiness before providing access to networks. These guidelines serve as a framework for identity proofing, enrollment, authentication and federation that provide government information systems against hacker attacks.
Comparative to IAL2, IAL3 requires someone on-site during the proofing process – much like how security guards inspect ID documents before admitting people into offices or meeting rooms. Unfortunately for companies without this capacity, this restricts their population that can be verified while also creating significant supply chain management issues and significant overhead expenses in terms of devices configuration, software setup, physical security audits and other elements involved with creating a FedRAMP High ial3 identity verification software.
SP 800-63-4 has updated these levels by mandating higher assurance authenticators such as phishing-resistant methods like FIDO Passkeys in AAL2 and AAL3, providing more flexibility for remote identities as it permits any AAL certified method that provides the assurances specified for that AAL level.
Trustswiftly stands out as the only CSP to achieve both FedRAMP High authorization and Kantara certification – two accolades which guarantee compliance with even the strictest civilian agency requirements for identity proofing, authentication, and federation. This impressive double certification ensures uncompromising digital identity protection for organizations of any kind.
