Federal Assessments

FISMA NIST 800-53

While only government agencies can be FISMA compliant, we can provide both independent attestations and gap assessments against the NIST 800-53 standards which are the detailed requirements behind FISMA.

What is NIST 800-53?

The Federal Information Security Management Act (FISMA) requires federal agencies, departments, and contractors to adequately safeguard information systems and assets. The underlying requirements for systems that handle government data come from NIST Special Publication (SP) 800-53.

Being an accredited 3PAO and having significant experience with the largest subservice organizations providing services to the federal government, our team has the experience needed in providing a quality assessment.

Your NIST 800-53 Specialist,
Steve Halbrook

Steve Halbrook is a Principal at Schellman. Steve is a FedRAMP and FISMA practice leader and assists with service delivery across all service lines including SOC, PCI-DSS, ISO, FedRAMP, FISMA and HIPAA services.

How much will your audit cost?

Whether it is an ISO 27001 certification, SOC 2 examination or a FedRAMP assessment, companies are often challenged by the need to address customer requirements while ensuring a return on compliance investment.

The most important factor in scoping a potential assessment is understanding what deliverable the recipient (i.e. your customer or partner) is expecting.
