Protecting Controlled Unclassified Information

NIST SP 800-171 implementation built around the real CUI environment.

Hatty AI helps organizations translate NIST 800-171 requirements into technical controls, operational procedures, documented ownership, and evidence that can be maintained over time.

Request a NIST 800-171 gap review

What an implementation program should cover

Map where CUI is stored, processed, transmitted, backed up, and accessed.

Define system boundaries, users, external service providers, endpoints, cloud platforms, and administrative paths.

Assess each applicable NIST SP 800-171 requirement against the real implementation and available evidence.

Build a prioritized remediation backlog with owners, dependencies, milestones, and verification steps.

Create or update the SSP, procedures, diagrams, inventories, and supporting evidence.

Establish recurring review so the documented state does not drift away from the technical state.

Start with the CUI boundary

Many expensive compliance mistakes begin with an unclear boundary. If the organization does not know which users, systems, applications, integrations, backups, and vendors can touch CUI, it cannot make good decisions about control implementation. We begin by documenting that boundary and identifying opportunities to reduce unnecessary exposure.

Implement controls in a sequence that makes operational sense

Some controls depend on others. Identity, asset inventory, configuration management, logging, access control, backups, incident response, and administrative practices often intersect. We organize remediation so foundational work is completed before dependent controls are treated as finished.

Make the SSP describe reality

The System Security Plan should explain how the organization meets requirements in the environment that actually exists. Hatty AI can help connect technical configuration, policies, procedures, diagrams, responsibilities, and evidence so the documentation remains useful to operators and reviewers.

Maintain the program after the initial push

Compliance can degrade when staff, vendors, software, networks, and business processes change. We can help establish review cadences, evidence collection, issue tracking, reporting, and technical maintenance so the program does not become a one-time documentation exercise.
