NIST Compliance Services
Control assessments, evidence gathering, and supply chain risk management across the NIST Special Publication framework family.
What We Cover
The NIST Special Publication series forms the backbone of federal cybersecurity compliance and informs the security programs of defense contractors, critical infrastructure operators, and regulated industries. The three publications below address different but related problems: how your controls are implemented (800-53), how your suppliers are managed (800-161), and whether you can prove it to the DoD (800-171 / CMMC). Many organizations need more than one.
NIST SP 800-53
Security & Privacy Control Assessment
The federal control catalog. Mandatory for agencies under FISMA; required for FedRAMP authorization. We assess your controls against the appropriate impact baseline (Low, Moderate, or High), collect evidence, and produce the SSP, SAR, and POA&M required for ATO packages.
NIST SP 800-161
Supply Chain Risk Management
The C-SCRM framework. Required for FISMA and Executive Order 14028 compliance. We inventory your technology suppliers, risk-tier them, assess your practices against the 800-53 SR control family, and build the policy, program documentation, and vendor controls that make supply chain risk management operational.
CMMC Level 1
FCI Self-Assessment & SPRS Affirmation
For contractors handling Federal Contract Information. We audit your implementation of the 17 FAR 52.204-21 practices, document the evidence, and prepare your senior official for the annual SPRS affirmation. False Claims Act exposure makes accuracy non-optional.
NIST SP 800-171 / CMMC Level 2
CUI Control Audit & C3PAO Preparation
For contractors handling Controlled Unclassified Information. CMMC Level 2 requires assessment against all 110 NIST SP 800-171 requirements. We audit your controls, collect and organize the evidence a C3PAO assessor expects, and build your SSP and POA&M.
These frameworks are related, not redundant. NIST 800-53 and 800-171 address overlapping but distinct control sets. 800-161 extends both by addressing the risks that come through your suppliers. Organizations pursuing FedRAMP, CMMC, or FISMA compliance often need elements of all three, and the documentation produced for one engagement informs the others.
How to Choose
| Your situation | Start here |
|---|---|
| Federal agency or contractor pursuing an ATO or FISMA compliance | NIST SP 800-53 |
| SaaS or cloud provider pursuing FedRAMP authorization | NIST SP 800-53 |
| Defense contractor handling FCI (not CUI), needing annual SPRS affirmation | CMMC Level 1 |
| Defense contractor handling CUI, facing CMMC Level 2 or C3PAO assessment | CMMC Level 2 / NIST SP 800-171 |
| Organization with complex technology vendor ecosystem and no formal supplier risk program | NIST SP 800-161 |
| FISMA or FedRAMP engagement with supply chain documentation gaps | 800-53 + 800-161 |
