Vencore Third Party Assessment Organization (3PAO)

Vencore 3PAO is accredited by the Federal Risk Authorization and Management Program (FedRAMP℠) to perform initial and periodic assessments of security controls for Cloud Service Providers (CSP).

Vencore 3PAO has extensive experience in security control implementation and the evaluation of mission critical information systems for various government agencies. We provide clients with the technical, policy and operational insight required for a successful compliance assessment to achieve FedRAMP Authority to Operate (ATO) certification, FISMA Compliance (NIST 800-53 Rev 4), NIST 800-171 Compliance and Department of Defense (DoD) Risk Management Framework (RMF) compliance.

Granted initial accreditation under FedRAMP in July 2013, Vencore was successfully re-certified by the American Association for Laboratory Accreditation (A2LA) in October 2017.  As FedRAMP will only review security assessment packages from CSPs that have been assessed by an accredited 3PAO, Vencore 3PAO provides the path for either the preparation of assessment, or the formal assessment itself.  We provide multiple levels of security assessment services for cloud products and services to help our customers comply with FedRAMP requirements.
