"110 controls. Each one implemented, not just documented."
All 110 NIST 800-171 Requirements — Technical Controls Built as Immutable Infrastructure
NIST SP 800-171 contains 110 security requirements across 14 control families. VIS LLC implements the technical controls with infrastructure as code, Azure Policy and automated configuration management, so your environment is immutable: systems are built from a reviewed baseline, compliance is enforced by configuration rather than maintained by procedure, and every new deployment inherits that baseline automatically. Policy, people and physical requirements are implemented and documented alongside them.
Configuration drift is a common reason controls fail an assessment. With immutable infrastructure, changes go through reviewed code, and Azure Policy and automated configuration checks catch deviations before they become audit findings.
Key Features
All 110 requirements addressed
We work through every requirement in all 14 control families and build the technical controls into your environment, not just into your SSP.
IaC-based control enforcement
Controls are enforced via infrastructure as code, Azure Policy, and automated configuration management — configuration drift triggers automatic detection and remediation.
CUI protection architecture
We design and implement the technical architecture required to protect CUI throughout its lifecycle in your environment.
System Security Plan (SSP) development
We develop an SSP that accurately reflects your implemented controls, aligned to the format C3PAO assessors expect.
SPRS score improvement
By implementing controls that were previously unmet, we improve your NIST 800-171 self-assessment score and reduce FCA exposure.
Ongoing compliance monitoring
We configure monitoring to detect configuration drift and alert your team before deviations become assessment findings.

Frequently Asked Questions
What is NIST 800-171?
NIST SP 800-171 (Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations) is a set of 110 security requirements across 14 control families that DoD contractors must implement to protect CUI. It is the foundation of CMMC Level 2. Compliance with NIST 800-171 is required under DFARS 252.204-7012 for any contractor that processes, stores, or transmits CUI.
How many controls are in NIST 800-171?
NIST SP 800-171 rev 2 contains 110 security requirements organized across 14 control families: Access Control (22), Awareness and Training (3), Audit and Accountability (9), Configuration Management (9), Identification and Authentication (11), Incident Response (3), Maintenance (6), Media Protection (9), Personnel Security (2), Physical Protection (6), Risk Assessment (3), Security Assessment (4), System and Communications Protection (16), and System and Information Integrity (7).
What is the difference between NIST 800-171 and CMMC?
NIST SP 800-171 is the set of 110 security requirements that defines what you must implement. CMMC (Cybersecurity Maturity Model Certification) is the DoD's program for verifying that you implemented them, through self-assessment or an assessment by a C3PAO (CMMC Third-Party Assessment Organization), depending on your contract. NIST 800-171 defines the 'what'; CMMC defines how it is verified.
What is a System Security Plan (SSP)?
A System Security Plan (SSP) is a document that describes how each of the 110 NIST 800-171 requirements is implemented in your environment — or planned to be implemented via a Plan of Action and Milestones (POA&M). The SSP is a required artifact for CMMC Level 2 assessment. It must accurately describe your CUI boundary, system components, and control implementations with supporting evidence.
