What is a NIST CSF Assessment?

A NIST CSF assessment evaluates an organization’s cybersecurity practices against the guidelines and best practices outlined in the NIST Cybersecurity Framework. This framework helps organizations understand, manage, and reduce their cybersecurity risks.

What Is the NIST Cybersecurity Framework?

The NIST Cybersecurity Framework (CSF) provides a structured set of cybersecurity practices designed to help businesses manage cyber risk across complex technology environments.

The framework focuses on five core cybersecurity functions:

  • Identify – Understanding systems, assets, and cybersecurity risks
  • Protect – Implementing safeguards to protect business systems and data
  • Detect – Monitoring systems to identify potential cybersecurity events
  • Respond – Responding effectively to cybersecurity incidents
  • Recover – Restoring systems and operations after a security incident

Many companies adopt the NIST CSF to guide the development of cybersecurity programs that align with recognized security practices used by government agencies and private industry.

Businesses that work with the federal government, particularly companies supporting the Department of Defense, must implement the security controls defined in NIST Special Publication 800-171.

NIST SP 800-171 establishes security requirements designed to protect Controlled Unclassified Information (CUI) stored or processed within contractor systems.

Tanner Security helps companies evaluate whether their cybersecurity controls meet the requirements defined within NIST 800-171.

Our NIST 800-171 compliance assessments review all required control families, including:

  • Access control
  • Identification and authentication
  • Incident response
  • Configuration management
  • System and communications protection
  • Audit and accountability
  • Risk assessment
  • Security awareness training

These assessments help a company understand which controls have been implemented effectively and which require additional improvement.

Many businesses struggle to evaluate the effectiveness of their cybersecurity programs without an independent review.

Tanner Security conducts NIST-based cybersecurity risk assessments that measure a company’s security posture against the practices defined within the NIST Cybersecurity Framework.

During these engagements, our consultants evaluate:

  • network security architecture
  • identity and access management controls
  • vulnerability management processes
  • endpoint security practices
  • incident detection and response capabilities
  • governance and security policies

The assessment process provides leadership teams with a clear view of cybersecurity risks affecting the business and the actions required to strengthen defenses.

Implementing the NIST Cybersecurity Framework requires more than reviewing documentation. Businesses must translate framework guidance into practical security controls that operate effectively across their technology environment.

Tanner Security helps companies implement the framework by:

  • evaluating current cybersecurity maturity
  • identifying security control gaps
  • developing prioritized remediation plans
  • aligning cybersecurity policies with NIST standards
  • improving security monitoring and incident response processes

This approach allows a company to gradually strengthen its cybersecurity program while aligning with a nationally recognized security framework.

Companies preparing for government contracts or regulatory reviews often begin with a NIST 800-171 gap assessment.A gap assessment compares a company’s existing cybersecurity controls against the 110 security requirements defined in NIST SP 800-171.

Tanner Security identifies areas where controls are incomplete, improperly implemented, or unsupported by documentation. These findings provide a clear roadmap for improving security controls and preparing for regulatory or contractual cybersecurity requirements.

Businesses across many industries rely on NIST frameworks to structure their cybersecurity programs.

Tanner Security works with companies including:

  • Healthcare providers protecting regulated patient data
  • Defense contractors implementing NIST 800-171 controls
  • Financial services firms are strengthening risk management programs
  • Technology companies securing cloud infrastructure
  • Manufacturing companies protecting operational systems

These industries often face increasing pressure from regulators, customers, and partners to demonstrate strong cybersecurity practices.

We love working with the Information Security team at Tanner Security Consultants. They customized their service offerings to fit our needs and put together a team of well-qualified individuals to work with us. Their team has exceeded my expectations.
