NIST · CSF 2.0 · 800-53 Rev 5 · 800-171 Rev 3 · 800-66 Rev 2

Every NIST publication on one platform.

CSF 2.0 (Feb 2024). 800-53 Rev 5.2.0 (March 2025). 800-171 Rev 3 (May 2024). 800-66 Rev 2 (Feb 2024). Every refresh in the last 18 months landed on a different team. RiskWatch runs them on one platform with cross-mapping so a control implemented once satisfies CSF, 800-53, 800-171, 800-66, FedRAMP, CMMC, FISMA, and the HIPAA Security Rule simultaneously.

What it is

What is NIST compliance software?

The NIST cyber library has six load-bearing publications and four 2024 refreshes. RiskWatch operationalizes NIST CSF 2.0, SP 800-53 Rev 5, SP 800-171 Rev 3, SP 800-66 Rev 2, SP 800-30 risk assessment methodology, and SP 800-37 Risk Management Framework on one survey-based platform with cross-mapping so a single control implementation satisfies multiple NIST frameworks plus FedRAMP, CMMC, FISMA, HIPAA Security Rule, and HITRUST CSF overlays.

The NIST family

Six publications. One operating model.

CSF gives you the framework. 800-53 gives you the control catalog. 800-171 tailors it for CUI. 800-66 tailors it for PHI. 800-30 + 800-37 give you the assessment + lifecycle methodology. Each builds on the others.

NIST CSF

2.0 (Feb 2024)
Any organization seeking a cyber framework

Six functions: Govern, Identify, Protect, Detect, Respond, Recover. The new Govern function reflects the 2.0 update. The flexible cybersecurity baseline that maps cleanly to every other NIST publication.

Explore NIST CSF

NIST SP 800-53

Rev 5 + Rev 5.2.0
Federal agencies, FedRAMP, FISMA-regulated systems

1,189 controls across 20 families, the most comprehensive control catalog in the NIST library. Tailored by impact level (Low, Moderate, High) and overlay (privacy, supply chain, cloud).

Explore NIST SP 800-53

NIST SP 800-171

Rev 3 (May 2024)
DoD contractors handling CUI, CMMC Level 2

110 controls (down from 110+ in Rev 2 with re-alignment) protecting Controlled Unclassified Information. Mandatory for DoD contractors via DFARS 252.204-7012; also drives CMMC Level 2 certification.

Explore NIST SP 800-171

NIST SP 800-66

Rev 2 (Feb 2024)
Healthcare covered entities and business associates

Implementation guidance for the HIPAA Security Rule (45 CFR 164 Subpart C). Operationalizes risk analysis, audit controls, contingency planning, and access management for PHI handlers.

Explore NIST SP 800-66

NIST SP 800-30

Rev 1
Any program needing a risk-assessment methodology

The risk-assessment methodology that underpins 800-39 and feeds 800-37 RMF Step 4. Likelihood × impact scoring, threat-source × vulnerability matrices, organizational + business + system tiers.

Methodology overlay (built into platform)

NIST SP 800-37

Rev 2 (RMF)
Federal agencies, FedRAMP, ATO-driven organizations

The 7-step Risk Management Framework: Prepare, Categorize, Select, Implement, Assess, Authorize, Monitor. The lifecycle that ties every NIST publication into one continuous workflow.

Methodology overlay (built into platform)
Cross-mapping

Implement once. Satisfy multiple NIST frameworks.

Every NIST publication carries explicit cross-references to the others. 800-66 Rev 2 maps every HIPAA Security Rule standard to applicable 800-53 controls. 800-171 Rev 3 derives from 800-53 Rev 5 (moderate baseline). CSF 2.0 sub-categories cross-reference to 800-53 + 800-171 controls. RiskWatch surfaces these maps in the controls library so an audit-ready evidence package covers every applicable framework simultaneously.

Cross-mapping extends beyond NIST: ISO 27001 Annex A, HITRUST CSF v11, PCI DSS v4 Trust Services Criteria, GDPR Article 32, and HIPAA Privacy + Breach Notification Rules all share evidence with the NIST baseline.

Decision guide

Which NIST framework do you actually need?

Pick by mandate first, then audience. Most organizations end up running two or three NIST publications simultaneously, which is exactly why cross-mapping matters.

NIST CSF 2.0

  • Building or maturing a cyber program from scratch
  • Communicating cyber posture to non-technical executives + boards
  • Aligning multiple business units to one cyber baseline
  • Pre-acquisition cyber due-diligence assessments

NIST 800-53 Rev 5

  • Federal agency or federal contractor work
  • FedRAMP Moderate or High authorization
  • FISMA compliance + annual assessment cycle
  • Need the most comprehensive control catalog available

NIST 800-171 Rev 3

  • DoD contracts referencing DFARS 252.204-7012
  • CMMC Level 2 certification path
  • Handling Controlled Unclassified Information (CUI)
  • Federal contracts referencing 800-171 in the SOW

NIST 800-66 Rev 2

  • Implementing the HIPAA Security Rule from scratch
  • Cross-mapping HIPAA to a broader cyber framework
FAQ

Common questions, answered up front.

About every NIST publication, the 2024 refreshes, the cross-mapping, and how to pick the right framework.

What is NIST compliance software?
NIST compliance software is a platform that operationalizes one or more NIST publications, NIST CSF 2.0, NIST SP 800-53 Rev 5, NIST SP 800-171 Rev 3, NIST SP 800-66 Rev 2, NIST SP 800-30 risk assessment methodology, and NIST SP 800-37 Risk Management Framework. RiskWatch covers all of them on a single survey-based assessment platform with cross-mapping so a control implemented once satisfies multiple NIST frameworks plus FedRAMP, CMMC, FISMA, HIPAA Security Rule, and HITRUST CSF overlays.
Which NIST framework do I need?
Pick by mandate first, then audience. Federal agencies + FedRAMP = 800-53. DoD contractors handling CUI = 800-171 (drives CMMC Level 2). HIPAA-regulated entities = 800-66 Rev 2 implementation guide for the HIPAA Security Rule. Any organization wanting a flexible cyber baseline = CSF 2.0. The 800-30 + 800-37 publications are methodologies that underpin all of the above. RiskWatch supports all six on one platform.
What changed in NIST CSF 2.0 (February 2024)?
CSF 2.0 added a sixth function, Govern, sitting alongside Identify, Protect, Detect, Respond, and Recover. The Govern function consolidates organizational context, risk strategy, supply-chain risk management, and oversight into one explicit function. CSF 2.0 also expanded applicability beyond critical infrastructure to all organizations and added implementation examples + tier-2 sub-categories. RiskWatch ships CSF 2.0 with a transition mapper from CSF 1.1.
What changed in NIST 800-53 Rev 5.2.0?
Rev 5 (Sept 2020) added the Privacy and Supply Chain Risk Management control families and re-organized for Federal Civilian Executive Branch agencies. Rev 5.2.0 (March 2025) added implementation examples, refined assessment procedures, and expanded the OSCAL machine-readable formats. RiskWatch supports the full 1,189-control catalog with impact-level baselines (Low/Moderate/High) and tailoring by overlay.
What changed in NIST 800-171 Rev 3 (May 2024)?
Rev 3 re-aligned 800-171 to 800-53 Rev 5 (moderate baseline), removed the 'basic' vs 'derived' security requirement distinction, added Organization-Defined Parameters, and clarified the relationship to 800-171A assessment procedures. CMMC Level 2 certification now references Rev 3. RiskWatch ships Rev 3 with a Rev 2 → Rev 3 transition mapper.
What is the NIST Risk Management Framework (800-37)?
RMF is the 7-step lifecycle that operationalizes NIST cybersecurity publications: (1) Prepare, (2) Categorize the system, (3) Select controls (from 800-53), (4) Implement, (5) Assess (using 800-53A or 800-30), (6) Authorize (ATO decision), (7) Monitor continuously. RMF is the operating model for FedRAMP authorization and FISMA annual cycles. RiskWatch runs every step from one platform with the audit trail every assessor expects.
Can RiskWatch cross-map NIST to non-NIST frameworks?
Yes. NIST CSF + 800-53 + 800-171 + 800-66 cross-map to ISO 27001 Annex A, HIPAA Security Rule, HITRUST CSF v11, PCI DSS v4, SOC 2 Trust Services Criteria, FedRAMP, CMMC Levels 1–3, GDPR Article 32, and CCPA cybersecurity audit requirements. One control implementation can satisfy multiple regulators. The cross-mapping lives in the controls library, no parallel binders.
Is there a free trial?
Yes. The 30-day free trial includes full access to every NIST framework (CSF 2.0, 800-53 Rev 5, 800-171 Rev 3, 800-66 Rev 2, 800-30, 800-37 RMF) plus all cross-mapping overlays. Run a real assessment against your own organization and decide before purchasing.
