NIST SP 800-63-4 represents an ambitious attempt to update digital identity guidelines, taking into account new threats and user needs. Key updates include shifting away from a checklist-based approach towards continuous evaluation; recognising phishing-resistant methods like FIDO Passkeys as well as officially integrating user-controlled wallets; as well as updating an outdated list.
HyPR offers organizations the means to achieve compliance with IAL3 through chat, video, facial recognition with liveness detection technology and document authentication – helping reduce cyber liability insurance premiums while simultaneously decreasing operational expenses by decreasing attack surface area.
IAL3 Verification
NIST SP 800-63-4 was released as final version in 2025, marking an important transition from checklist-based requirements to risk-based Digital Identity Risk Management (DIRM). The updated guidelines prioritize extensive identity proofing, strong phishing-resistant authentication and secure federated identity practices; email OTP authentication was phased out while focus was given to multifactor authentication (MFA and passkeys), along with remote identity proofing for IAL2, mobile driver’s licenses and user controlled wallets as a priority.
The new guidelines emphasize the need to limit highly scalable attacks, protect against synthetic identities, and limit access that could expose critical information about one or more users to large-scale exploitation by malicious actors. They advise agencies carefully selecting Identity Assurance Level (IAL), Authenticator Assurance Level (AAL) or Federation Assurance Levels (FAL), depending upon both business risks and mission needs.
IALs define the levels of confidence an assertion made from one identity provider (Credential Service Provider or CSP) to another entity relying party, known as an RP. They offer low assurance that claimed digital identities belong to real world persons and may only require self-asserted attributes validated by CSP; with increasing levels of assurance necessitating authenticators collected; until finally reaching level 3, which requires in-person verification using biometric technology for maximum assurance.
IAL3 Compliance
Compliance with IAL3 standards demands a systematic shift. Defense contractors handling ITAR data, staff accessing critical infrastructure or administrators managing cloud environments all benefit from using a physical hardware model that enforces IAL3 standards to successfully neutralize modern industrial espionage threats and ensure supply chains’ integrity – not to mention eliminate passwords or SMS OTPs for access control with their associated phishing-resistant security risks; in turn leading to significant reduction in cyber liability insurance premiums.
IALs measure the extent to which digital identities correspond with real world identities; federation levels measure how reliably IdPs (identity service providers) convey authentication and attribute information between IdPs and RPs (relying parties). NIST SP 800-63-4 has modernized IALs by including chat, video and biometric authentication as pathways towards providing assurance of identity assurance level 2 assurance, as well as formalizing an evaluation program with recommended metrics.
Trustswiftly’s nist ial3 verification solution leverages a FIDO Certified passwordless authenticator, hardware-backed biometrics and live face recognition with certified 3D liveness detection to verify true identity on controlled, tamper-evident hardware. It effectively prevents phishing attacks, bypasses proxy servers and exposes synthetic deepfakes while meeting NIST IAL3 requirements for FedRAMP high authorization.
IAL3 Identity Verification Software
The latest version of the Digital Identity Guidelines, NIST SP 800-63-4 IAL3, significantly enhances measures to combat identity theft and fraud. Notably, it deprecates email OTP and downgrades SMS-based authentication to AAL1. It also mandates phishing-resistant MFA and integrates Passkeys while establishing FIDO2 as the new standard for device-based authentication. In addition, it defines a set of assurance levels (IALs) and requires that the user’s enrollment processes, management processes, authenticators, and associated assertions be robust against attacks.
IAL3 authentication provides high confidence that a claimed digital identity corresponds to a real-world identity with a level of certainty ranging from AAL1 (self-asserted) to IAL3 (in-person verification). The highest assurance level requires the use of strong authentication technologies such as device-bound, passwordless FIDO security keys and facial recognition with liveness detection to prevent spoofing attacks like deepfakes and other man-in-the-middle techniques.
Trustswiftly ial3 identity verification software helps organizations achieve nist 800-63-4 ial3 compliance with ease by eliminating vulnerable, password-based authentication methods. Our patented face authentication compares real-time biometric data to verify that the person behind the screen is truly present. Using a combination of infrared and visible light sensing to detect depth, brightness, and movement, our facial biometrics ensure that the user is presenting themselves, preventing spoofing attempts. In addition, iProov’s Dynamic Liveness detects the presence of a live human and captures unique, real-time biometric data to prevent spoofing attempts using photos or video clips.
Fedramp High Identity Proofing
FedRAMP Low and Moderate authorization levels are appropriate for public-facing websites or non-sensitive systems, while FedRAMP High authorization level should only be awarded to systems processing sensitive Controlled Unclassified Information (CUI), such as federal procurement portals, law enforcement access to investigative data or healthcare repositories. In order to gain FedRAMP High authorization level status, organizations must prove they can protect such high impact systems against phishing attacks, man-in-the-middle attacks and MFA fatigue through hardware-anchored identity verification with granular logging and continuous monitoring.
FedRAMP High certification requires rigorous evaluations and extensive documentation, as well as substantial investments in security technology and personnel, but achieving success in these assessments can reap long-term rewards in mitigating risks for decades to come. Furthermore, being FedRAMP Certified opens doors to niche government markets requiring the highest security assurance levels.
By pairing Trustswiftly’s fedramp high identity proofing solution with a comprehensive threat mitigation platform, organizations can achieve an holistic risk-based approach to cybersecurity. This eliminates multiple point-in-time checks with ongoing, automated reproofing based on user risk; significantly decreasing attack surface size while saving operational costs by fewer password resets. Ultimately delivering superior customer experiences by way of stronger authentication and increased privacy protections than traditional password-based methods.
