Identity proofing at IAL3 level requires additional evidence to protect applicants and relying parties from impersonation and fraud, according to the 800-63-3 guidelines document. Please see table below for details.

The 2025 revisions to the NIST Digital Identity guidelines signify a major shift toward prioritizing stronger authentication protocols that resist phishing attacks and secure federated identity management systems, while supporting modern identity proofing methods like mobile driver's licenses or syncable authenticators like passkeys. Furthermore, accessibility requirements support modern proofing methods like mobile driver's licenses or syncable authenticators such as passkeys for identity proofing purposes.

IAL3 Compliant Solution

NIST provides identity assurance at three levels: Identity Level 3, which is its highest level; often used to secure privileged accounts or meet regulatory compliance. In the past, NIST IAL3 verification  required on-site proofing sessions with an agent present, but this process proved costly and unscalable for remote workforces creating logistical nightmares and security risks.

TrustSwiftly's fully managed remote, telepresence-based IAL3 solution eliminates the need for agents to be physically present during each session, meeting NIST standards while saving you money. Furthermore, document inspection and facial recognition technology is employed for fraud prevention as well as to perform document inspection and facial recognition - saving both time and money!

When using remote IAL3 identity proofing services, it's essential that authenticators is immediately linked with verified identity immediately after an IAL3 session has ended. This prevents stand-in fraud where someone else uses the same authenticator to gain entry to an account that you hold privileged access for. Furthermore, it is key that personal identifiable information stored is deleted promptly to avoid data breaches.

NIST IAL3 Verification

NIST security standards at their highest level require submission of superior-strength identity evidence and in-person or remote verification processes with an automated biometric system matching capability that fulfills NIST 800-63A IAL3 section 5.2.3 requirements.

IAL3 also requires verification of the integrity of submitted evidence, including whether or not it has been reported lost or stolen. Furthermore, this verification process must be recorded and auditable for audit purposes.

NIST's IAL3 requirements, along with those for AAL2, AAL4, and AAL5, offer tiered levels of confidence that an identity exists in the real world, providing users with secure authentication across multiple relying parties with one authentication event. NIST has recognized this need by deprecating email OTP authentication while significantly downgrading SMS-based authentication methods; their definition of Federated Assurance Levels (FALs) also supports this notion, enabling agencies to select an FAL that best meets their risk management and mission needs.

NIST IAL3 Identity Proofing

The NIST 800-63A IAL3 standard establishes three Identity Assurance Levels (IALs) to achieve balance among security, privacy, and usability. Level one does not require verification of claimed identities while levels two and three require strong evidence proving they do exist and that they belong to those presenting it.

IAL3 verification involves an in-person, attended process with stringent oversight that combines document validation and biometric information comparison in order to reduce risks of impersonation and fraud. As it is the highest level of assurance available, this procedure requires that an identity proofing service provider certify that all submitted information satisfies NIST 800-63A IAL3 requirements when verifying digital identities claimed online. Curious about NIST 800-63A IAL3?

TrustSwiftly, our comprehensive identity verification solution, helps organizations align business and security objectives by meeting NIST 800-63A requirements through chat, video, facial recognition with liveness detection, document authentication, step-up reproofing based on risk, step-down reproofing based on risk - helping avoid cyber liability claims while decreasing password reset costs and increasing overall security and resilience.

TrustSwiftly

TrustSwiftly's unique pay-as-you-go pricing package with no long-term contracts offers both automated and human-supervised verification methods, providing more flexible and accurate identity assurance than traditional solutions. Adaptive technology automatically adapts to dynamic risk, creating a flexible yet accurate identity assurance model.

IAL3 compliant solution redefines identity assurance by emphasizing modular components such as Identity Proofing (IAL), Authentication (AAL), and Federation (FAL). When combined with Zero Trust security architectures, compliance becomes an ongoing operational process that assesses contextual risk to make authentication, authorization, and federation decisions that are verified, adaptive, and self-sustaining.

Tradition dictates that establishing identity at an IAL3 level requires in-person visits by certified examiners, which often creates logistical and compliance bottlenecks for businesses. TrustSwiftly offers an innovative hardware-based remote IAL3 compliant solution which meets NIST standards, saves money and helps reduce security risks while satisfying auditors. Their solution also features a public bounty challenge to demonstrate its resilience against attacks by inviting security researchers and ethical hackers to attempt bypassing its defenses.
