IAL3 requires more rigor in identity proofing and in-person verification processes to protect against scaled and targeted attacks, basic evidence falsification techniques and social engineering tactics.
With solutions such as Trust Swiftly’s supervised remote identity verification, you can achieve IAL3 assurance without needing to visit kiosks or hire agents. In addition, this solution manages retention schedules and permits reproofing as necessary, helping ensure compliance.
IAL3 Compliant Solution
NIST’s digital identity guidelines offer three levels of assurance. To attain it, an applicant must undergo an on-site attended identity proofing session with a trained CSP representative and obtain one or more biometric characteristics for collection. In addition, strong authentication protocols including multifactor authentication (MFA), hardware authenticators such as PIV/CAC cards as well as stringent chain of custody procedures and liveness detection/impersonation protection must also be implemented within its framework.
TrustSwiftly offers a managed solution for NIST IAL3 verification that’s powered by our secure eKYC platform and delivered through self-service kiosks or mobile apps. This meets IAL3 requirements for human oversight as well as IAL3 identity proofing methods like document validation, FIDO Passkey integration, facial recognition with liveness detection and dynamic knowledge-based authentication. In addition, sessions may be transferred for additional verifications such as device checks – this feature being especially helpful for remote workers unable to travel physically to an on-site location.
Cost-Effective
TrustSwiftly stands out as a cost-effective identity verification method due to the use of multiple verification techniques at once to quickly approve real e-commerce customers while quickly blocking fraudsters.
IAL3 requires that a trained CSP representative interact directly with applicants during an on-site attended identity proofing session and provides more evidence and stronger verification methods in order to limit fraud, theft, repudiation and any more advanced social engineering attacks.
While selecting an assurance level is relatively easy, meeting it may prove more complicated. Meeting it requires CSPs to satisfy numerous technical design, user experience and operational guardrails as well as rigorous conformance assessments and ongoing reviews in order to maintain their accreditation. Microsoft Azure AD provides authenticators and verifiers that meet AAL3 requirements such as FIDO2 security keys, smartcards and Windows Hello for Business authentication mechanisms that meet this criteria.
Scalable
NIST Special Publication 800-63 outlines several assurance levels that govern digital authentication. It specifies technical requirements for credential service providers (CSPs) enrolling and verifying identities using digital authentication processes that comply with certain Identity Assurance Levels; additionally it allows CSPs to exchange information among themselves using federation controls.
The latest version of NIST 800-63A IAL3 incorporates several notable upgrades over its predecessor guidelines, promoting more phishing-resistant methods like FIDO Passkeys while downgrading email one-time passwords to limited scope due to their susceptibility to widespread phishing attacks at work.
the guidelines now acknowledge remote identity proofing services that meet IAL3 requirements, with TrustSwiftly being recognized formally in FedRAMP High guidelines as one such hardware-based verification solution. TrustSwiftly’s flagship remote IAL3 verification solution uses automated and human oversight with mobile apps and self-service kiosks offering document validation, biometric authentication and dynamic knowledge-based authentication to meet these new guidelines efficiently and cost-effectively.
Easy to Implement
The 2025 version of NIST 800-63A IAL3 moves away from checklist-based requirements in favor of a risk-based digital identity risk management framework. It details modular assurance components that evaluate each stage of identity lifecycle evaluation: IAL, AAL and FAL. IAL ensures accurate identity verification while AAL governs authentication strength utilizing MFA or hardware authenticators like PIV/CAC cards as authenticators against phishing; FAL sets standards for federated identity transactions using encrypted and standards-compliant assertion handling via SAML 2.0 and OIDC respectively.
TrustSwiftly’s NIST 800-63A IAL3 solution aims to address compliance bottlenecks by offering an automated hardware-based verification process that meets the highest assurance levels outlined by NIST SP800-63-4 guidelines. In contrast with traditional in-person proofing methods which can be costly and unscalable for remote workforces, our cost-effective and rapid implementation IAL3 verification solution meets FedRAMP High authorization requirements while offering an audit trail. As a result, this makes our IAL3 verification solution highly valuable for CSPs seeking NIST IAL3 certification.
