NIST CSF 2.0 · Updated February 2024

A Flexible Cybersecurity Foundation for Any Organization

The NIST Cybersecurity Framework is the most widely adopted cyber risk management framework in the world — voluntary, outcome-focused, and applicable to organizations of any size or sector. CSF 2.0 added a Govern function and broadened applicability beyond critical infrastructure. We help organizations adopt it as a stepping stone toward FedRAMP, FISMA, or CMMC.

Why It Matters

What NIST CSF Means for Your Organization

The NIST Cybersecurity Framework was first published in 2014 to help operators of critical infrastructure manage cyber risk. CSF 2.0, released in February 2024, expanded its scope to organizations of every size, sector, and maturity level. The framework is voluntary in most contexts but increasingly required by state laws, insurers, and trading partners.

Voluntary but Widely Required

CSF is voluntary federally but is referenced in state cybersecurity laws (NY DFS Part 500, California, Ohio), Executive Order 13800 for federal agencies, and many cyber insurance underwriting requirements.

Outcome-Focused, Not Prescriptive

CSF describes what good cybersecurity looks like rather than mandating how to achieve it. Organizations can implement subcategories using technologies and processes that fit their environment.

Common Cyber Language

CSF gives executives, technologists, regulators, and partners a shared vocabulary for discussing cyber risk — making board reporting, vendor risk management, and audit communications dramatically easier.

Direct Path to Other Frameworks

Every CSF subcategory has informative references to NIST 800-53, NIST 800-171, ISO 27001, CIS Controls, and COBIT — so CSF work compounds toward formal certifications.

NIST CSF 2.0 — Released February 2024

Six Functions, 23 Categories, 106 Subcategories

NIST Cybersecurity Framework 2.0 is structured around six high-level Functions that work together as a strategic lifecycle for managing cybersecurity risk. Version 2.0 added a new Govern function and broadened the framework’s applicability beyond critical infrastructure to all sectors.

Govern (NEW in 2.0) Establish, communicate, and monitor the organization’s cybersecurity risk management strategy, expectations, and policy. Wraps around all other functions.
Identify Develop organizational understanding of assets, business environment, governance, risk assessment, risk management strategy, and supply chain risk.
Protect Develop and implement safeguards to ensure delivery of critical services. Includes identity management, awareness, data security, and protective technology.
Detect Develop and implement activities to identify cybersecurity events: anomalies, security continuous monitoring, and detection processes.
Respond Develop and implement appropriate activities to take action regarding a detected cybersecurity incident: response planning, communications, analysis, mitigation.
Recover Develop and implement activities to maintain plans for resilience and to restore capabilities or services impaired due to a cybersecurity incident.
Implementation Tiers & Profiles

Tiers Describe Maturity, Profiles Describe Posture

The CSF avoids prescribing a single right answer. Instead, organizations select Implementation Tiers reflecting how rigorously they manage cyber risk, then build Profiles capturing where they are today (Current Profile) and where they need to be (Target Profile).

Tier 1

Partial

Ad-hoc, reactive
  • Risk management is informal and ad-hoc
  • Limited awareness of cyber risk at organizational level
  • Cybersecurity activities not integrated with risk management
  • Common starting point for organizations beginning their CSF journey
Tier 2

Risk Informed

Aware but not consistent
  • Risk management practices approved but not org-wide policy
  • Senior leadership aware of cyber risk
  • Cybersecurity awareness exists but not formalized
  • Inconsistent implementation across business units
Tier 4

Adaptive

Predictive, continuous
  • Continuous improvement using lessons learned
  • Predictive cyber risk indicators
  • Cybersecurity is part of organizational culture
  • Real-time information sharing with external parties
CSF as the On-Ramp

CSF Maps to Every Other Compliance Framework

The CSF is voluntary and outcome-focused — making it the most common starting point for organizations preparing for stricter regimes like FedRAMP, FISMA, NIST 800-171, or HIPAA. Its informative references map directly to those frameworks, so the work you do for CSF flows through to formal certification efforts.

The GovDataHosting Process

Your Path to NIST CSF Compliance

Our proven methodology shortens timelines and reduces risk by combining inheritable controls, dedicated compliance staff, and direct experience with CSF-aligned authorizations.

Step 1

Scope & Prioritize

Identify business mission, critical services, and data flows. Set the boundary for your CSF program and prioritize functions for early focus.

Step 2

Current Profile

Document your current cybersecurity posture across all six functions. Identify which subcategories are implemented, partial, or absent.

Step 3

Target Profile & Gap

Define your Target Profile based on risk tolerance, mission, and external requirements. Compare to Current Profile to surface gaps.

Step 4

Implement & Measure

Close the gaps in priority order. Operate on FedRAMP High infrastructure to inherit Protect / Detect / Respond / Recover capabilities.

Frequently Asked Questions

NIST CSF FAQs

Is CSF compliance audited or certified?

There is no formal CSF certification body. Organizations self-attest to their CSF posture, often using an independent assessor to validate the Current Profile and the Target Profile gap analysis. CSF maturity is more commonly demonstrated through customer due diligence questionnaires, regulatory submissions, and insurance applications than through formal certification.

How does CSF 2.0 differ from CSF 1.1?

The biggest change is the addition of the Govern function — making cybersecurity governance an explicit, top-level concern rather than a subcategory inside Identify. CSF 2.0 also broadens applicability beyond critical infrastructure, adds explicit small-business guidance, refreshes informative references to current NIST publications including 800-53 Rev 5, and integrates supply chain risk management more deeply.

Should we use CSF or jump straight to NIST 800-53?

If you are pursuing a federal authorization, NIST 800-53 (via FISMA or FedRAMP) is the destination — there is no avoiding it. CSF is the better starting point if your organization is establishing a cybersecurity program from scratch, lacks a formal regulatory mandate, or needs a vehicle for executive risk conversation. Many organizations use CSF to organize their program and NIST 800-53 to satisfy specific authorization requirements.

How does GovDataHosting support a CSF implementation?

Operating on our FedRAMP High infrastructure means most of your Protect, Detect, Respond, and Recover function subcategories are pre-implemented at the infrastructure layer. Your team focuses CSF program effort on Govern and Identify — the strategy, asset inventory, and risk management work that only your organization can do. We provide cross-reference documentation showing how our infrastructure maps to specific CSF subcategories.
