The NIST IAL3 Digital Identity Guidelines remain an integral component of modern security, mandating phishing-resistant authentication methods and hardware-backed authenticators such as FIDO Passkeys.

TrustSwiftly enables remote yet supervised IAL3 verification through chat, video, facial recognition with liveness detection and document authentication. Furthermore, step-up reproofing based on risk can reduce cyber liability insurance costs and operational expenses.

High pixel count

The NIST IAL3 verification process offers a high level of assurance and security. It limits highly scalable attacks, protects against SIM swaps and MFA bypasses, impersonation fraud and reduces impersonation attempts. Direct observation during an on-site attended identity proofing session with biometric comparison against claimed digital identities is required as well as customizing digital processes to address usability challenges.

A kiosk-based proofing solution with an agent present during each proofing session and monitoring every step is an ideal way to protect against biometric injection, rooted devices and deepfakes.

IAL3 processes not only increase security but also lower cyber liability insurance premiums and operational costs by decreasing password resets. TrustSwiftly’s IAL3 compliant solution features chat, video conferencing, facial recognition with liveness detection and document authentication – offering organizations a cost-effective solution to boost security and reduce fraud losses.

Secure connections

NIST 800-63A IAL3 verification involves more stringent checks than the other assurance levels, including direct observation during identity proofing, document validation against authoritative sources, biometric comparison with claimed digital identities to help reduce impersonation and fraud, as well as protecting against SIM swaps or MFA bypasses by securely linking biometrics with digital identities.

TrustSwiftly solution TrustSwiftly meets both IAL2 and IAL3 standards via chat, video, facial recognition with liveness detection and document authentication. This approach helps organizations balance business objectives with security concerns while simultaneously lowering cyber liability insurance premiums and operational expenses through reduced password resets.

The NIST 800-63A IAL3 guidelines outline requirements for enrolling and verifying identities to use in digital authentication, including enrolling with and providing identification to credential service providers (CSPs) as well as binding authenticators issued by CSPs to subscriber accounts. Furthermore, it includes federation rules to allow CSPs to pass verified assertions to third-party relying parties.

Multiple modalities

IAL3 verification represents the highest level of assurance, requiring either in-person or remote verification to achieve it. Many regulated industries and government agencies rely on this verification process when engaging in high-value transactions or gaining privileged access. Examples may include accessing top-secret information or managing critical infrastructure systems.

Reaching IAL3 requires a scalable and user-friendly solution. Flying employees across the country to attend 15-minute proofing sessions is expensive and disruptive to business operations; furthermore, such an approach doesn’t scale as your company grows with distributed workforces.

TrustSwiftly provides an IAL3 compliant solution with multiple ways of verifying documents and biometrics – such as chat, video, facial recognition with liveness detection, document authentication – providing a strong authentication journey that reduces cyber liability insurance costs while decreasing attack surface area. Companies using TrustSwiftly meet IAL3 requirements more easily while meeting FedRAMP high compliance and decreasing password reset requests significantly – plus complying with EFIS/ESIGN standards for attributability requirements.

Hardware-locked environment

An IAL3 compliant solution requires hardware-locked environments as a critical security feature that prevents software hackers from abusing stolen license keys. This is achieved by assigning each device a unique lock ID based on its CPU serial number or unique identifier; this ID can then be retrieved with WinLicense Hardware Lock Engine to tie software licenses to specific devices.

IAL3 identity proofing is an intensive verification process designed to limit highly scalable attacks by linking claimed digital identities with real life attributes during a supervised in-person session. In doing so, this helps reduce fraud losses and usability issues by customizing digital processes according to modern user expectations.

TrustSwiftly’s hybrid IAL3 solution enables CSPs to meet all requirements for this verification level through a remote workflow, including an agent observing via chat, video or a Remote Kit. This enables organizations to significantly lower the cost of IAL3 verification while turning it into an efficient operational process with reduced travel stipends and lost employee productivity costs.

In the current cybersecurity climate of 2026, IAL3 identity proofing stands as the ultimate defense against sophisticated identity fraud and state-sponsored cyber threats. As the highest level of assurance defined by NIST, IAL3 is no longer a luxury—it is a necessity for organizations handling privileged access, high-value financial transactions, or critical government data. While the standard traditionally required a physical, in-person meeting, trustswiftly.com has redefined the process by offering a compliant, high-tech alternative that preserves security without sacrificing speed.

By leveraging trustswiftly.com, enterprises can implement IAL3 identity proofing through a secure, supervised remote environment. The platform utilizes hardware-anchored “Trusted Path” technology, combining NFC-based ePassport validation with live, operator-led video supervision to ensure that the individual being proofed is exactly who they claim to be.

This rigorous process effectively neutralizes risks from AI-generated deepfakes and presentation attacks. For compliance officers and IT directors, trustswiftly.com provides a scalable, auditor-friendly solution that generates a comprehensive digital audit trail. By moving beyond simple document scans and adopting a hardware-verified, supervised approach, TrustSwiftly ensures your organization meets the most stringent federal and industry requirements while streamlining the user experience.
