NIST 800-63-4 updates the core structure of Identity Assurance Levels (IAL), Authentication Assurance Levels (AAL), and Federation Assurance Levels (FAL), while mandating more robust authentication techniques that ward off phishing attempts.

The new guidelines introduce a Digital Identity Risk Management (DIRM) framework which prioritizes resilience and context when verifying identities for system access, credential resets and increasing privilege levels. This approach is especially crucial when verifying identities to access systems or reset credentials.

Compliance Fedramp

While some organizations can manage compliance on their own, others struggle with time and skills shortages when it comes to IT professionals, leading to inconsistent security measures and opening the door for malicious actors.

Uneven practices can hinder efforts to identify potential vulnerabilities, while budget and resource restrictions make continuous monitoring challenging.

Security requirements evolve over time, necessitating organizations to regularly update policies and controls to stay compliant. Unfortunately, complex regulations can slow development speed significantly making it impossible to respond quickly enough to emerging threats.

fedramp high identity proofing provides cloud service providers (CSPs) with a set of standardized security requirements that they can use to help facilitate adoption of secure cloud products and services more quickly. Once completed, CSPs can receive Authorization to Operate (ATO) or Provisional Authorization to Operate (P-ATO) from federal agencies - providing an edge in government marketplace by becoming FedRAMP Ready certified.

High Identity Proofing

NIST SP 800-63-4 is the latest iteration of the National Institute of Standards and Technology's digital identity guidelines, offering organizations a framework for managing identity lifecycle processes including authentication, Federated Identity Management and more. This helps companies meet compliance requirements such as NIST IAL2, security frameworks like ISO 27001 or industry regulations like PCI DSS, GDPR or CCPA more easily.

Prior to, user onboarding could often be painful with multiple steps to verify identity and require numerous attributes such as secondary address or birth city to establish their credentials. Now, identity proofing services provide more user-centric approaches that use high assurance methods with reduced friction levels.

It can be accomplished using phishing-resistant authentication technologies such as FIDO security keys and cryptographic push notifications that offer greater flexibility while meeting the high assurance needs of IAL3 and IAL4 levels of assurance. Furthermore, cutting-edge facial biometrics technology is being utilized to detect spoofing attempts and verify people are alive - essential components in combatting phishing attacks and man-in-the-middle threats.

Reduced Risk

NIST 800-63-3 marked an important turning point towards prioritizing robust and phishing-resistant authentication and secure federated identity practices in 2025, mandating robust MFA, passwordless authentication and syncable passkeys like FIDO2 as the new baseline in IAL2, IAL3 and FAL1. In addition, its release also updated Digital Identity Risk Management framework by including an evaluation process beyond simply technical requirements that considers mission impact as well as impacts on users; adding weight to cybersecurity, user equity and individual rights considerations when assessing risks beyond technical requirements alone.

Our comprehensive ial3 identity verification software, Trustswiftly, directly supports NIST 800-63-3 guidelines by providing FIDO Certified IAL2 and IAL3 credentials and helping achieve nist 800-63-4 ial3 compliance through chat, video, facial recognition with liveness detection and document authentication. Furthermore, this step-up reproofing nist ial3 verification service helps reduce attack surface and ensure continuous identity assurance resulting in lower cyber liability insurance and less password resets as a result of reduced operational costs.

Increased Efficiency

Efficiency is a cornerstone of business success in today's fast-changing environment, driving both short- and long-term growth. Achieve it requires taking an proactive approach with continuous improvement strategies as well as adopting tools and techniques tailored specifically for efficiency improvement.

NIST 800-63-4 guidance promotes efficiency with its streamlined DIRM process that extends beyond enterprise risk to include impacts on mission delivery, the public trust and individual users (including equity). Furthermore, this guidance enhances security with requirements such as phishing-resistant authentication using FIDO Passkeys or user controlled wallets for AAL2 through AAL4. Furthermore, these guidelines promote more robust federations models by mandating stronger authentication at FAL level; [SP800-63A and SP800-63B] provide normative descriptions of authenticator management including choices made, resistance mechanisms as well as appropriate authentication processes tailored for each AAL level respectively.
