Independent NIST Security Audits for Businesses

Businesses increasingly rely on established cybersecurity standards to protect sensitive data, strengthen internal security controls, and manage technology risk. Among these standards, the National Institute of Standards and Technology (NIST) provides some of the most widely recognized cybersecurity frameworks used across both government and private companies.

Tanner Security provides independent NIST IT audit services that evaluate how effectively a company has implemented cybersecurity controls aligned with NIST standards.

Our team of consultants performs security audits that assess technical and administrative controls, documentation review, and security processes across a company’s IT environment. These audits provide leadership teams with a clear understanding of their cybersecurity posture and the areas that need improvement.

For many businesses, a NIST IT audit serves as a critical step in strengthening cybersecurity programs, preparing for regulatory requirements, or validating the effectiveness of existing security controls.

Evaluating Security Controls Against NIST Standards

NIST cybersecurity standards provide detailed guidance for protecting information systems, managing cybersecurity risk, and implementing structured security controls.

Tanner Security conducts IT audits that evaluate security controls aligned with widely recognized NIST publications, including:

• NIST Cybersecurity Framework (CSF)
• NIST Special Publication 800-171
• NIST Special Publication 800-53
• NIST Risk Management Framework

These frameworks provide structured guidance for implementing cybersecurity practices that protect sensitive business data and critical systems.

Through a NIST-aligned IT audit, Tanner Security evaluates whether a company’s security practices reflect the safeguards recommended by these standards.

NIST 800-171 Security Control Audits

Businesses that handle Controlled Unclassified Information (CUI), particularly companies that support federal agencies or defense programs, must demonstrate compliance with the security requirements defined in NIST SP 800-171.

Tanner Security performs NIST 800-171 IT audits that examine how a company has implemented the required security controls designed to protect sensitive government information.

Our consultants review all key control areas within the standard, including:

• access control and authentication practices
• system and communications protection
• configuration management controls
• audit logging and monitoring capabilities
• incident response procedures
• risk assessment processes
• security awareness training programs

This audit process helps a business determine whether its security controls effectively protect Controlled Unclassified Information.

Cybersecurity Governance and Risk Management Reviews

Strong cybersecurity programs depend on effective governance, clearly defined policies, and consistent risk management practices.

As part of a NIST IT audit, Tanner Security evaluates the governance structure that supports a company’s cybersecurity program.

Our consultants review:

• cybersecurity policies and procedures
• risk management practices
• asset management processes
• vendor and third-party security controls
• incident response planning
• security monitoring capabilities

This evaluation provides insight into whether a company has established the leadership oversight and internal controls required to support a mature cybersecurity program.

Technical Security Control Assessments

Beyond policy reviews, Tanner Security conducts detailed technical analysis of the systems and infrastructure that support a company’s technology environment.

Our NIST IT audits may include evaluation of:

• network security architecture
• identity and access management controls
• endpoint security protections
• vulnerability management practices
• logging and monitoring systems
• cloud infrastructure security

By examining both technical safeguards and operational processes, our consultants help businesses gain a comprehensive understanding of their cybersecurity posture.

Independent Security Audits for Regulated Businesses

Many industries face increasing pressure to demonstrate strong cybersecurity practices.

Companies frequently pursue NIST-aligned security audits when they must meet regulatory expectations, contractual security requirements, or internal governance objectives.

Tanner Security performs NIST IT audits for businesses operating in sectors including:

• healthcare
• financial services
• defense contracting
• technology and SaaS platforms
• manufacturing and industrial operations

These industries often manage sensitive information that requires strong cybersecurity protections and ongoing security oversight.
