This case study explains how Appian met the stringent FedRAMP High requirement for Identity Assurance Level 3 (IAL3) by partnering with NextgenID rather than building an in-house identity proofing solution. By deploying NextgenID’s fully managed, audit-ready IAL3 platform with supervised remote verification and global enrollment options, Appian accelerated its path to authorization, reduced operational burden and avoided significant compliance risk. As a result, identity proofing became a strategic advantage that strengthened Appian’s federal market readiness while scaling efficiently with its global workforce.
