NIST 800-171 Compliance
Most of the 110 security requirements in NIST 800-171 are operational, not one-time settings, so an assessment alone leaves you holding a POA&M you cannot close. eMazzanti implements and then operates the controls, backed by 4x Microsoft Solutions Partner status, WatchGuard Founding Partner credentials, and a 24/7 eCare SOC, serving businesses across New Jersey and the NYC metro area.
What is NIST 800-171 compliance?
NIST 800-171 compliance means implementing the 110 security requirements organized into 14 control families that NIST Special Publication 800-171 defines for protecting Controlled Unclassified Information in nonfederal systems. For Department of Defense contractors and subcontractors, it is required by DFARS 252.204-7012, and compliance is documented in a System Security Plan with a Plan of Action and Milestones for anything not yet met, then reported as a self assessment score in the Supplier Performance Risk System.
The difficulty is that scoring the 110 requirements is the easy part. Families such as audit and accountability, incident response, and system monitoring demand continuous operation, which is why a consultant's report so often ends as a POA&M that never closes. eMazzanti closes it and keeps it closed: we implement Microsoft 365 and Azure controls as a 4x Microsoft Solutions Partner, harden system and communications protection with WatchGuard, and run the continuous requirements through the 24/7 eCare SOC and eCare Cloud Backup, all delivered on the e365 platform with 25+ years of managed IT behind it.
Why NIST 800-171 Stalls Before the Controls Are Ever Implemented
Contractors rarely fail NIST 800-171 because they do not care about security. They fail because the requirements are operational, the paperwork is unowned, and nobody can produce evidence when a prime contractor asks. These are the gaps we find most often in a nist 800-171 gap analysis.
A DFARS clause with a self assessment due
Your contract carries DFARS 252.204-7012 and the 7019 and 7020 clauses, a self assessment is expected, and no one internally can produce an honest score to report.
An SPRS score that is negative or invented
Someone posted a score to satisfy a buyer without assessing the 110 requirements. A negative score blocks awards, and an invented one is a false claim waiting to be tested.
No System Security Plan
Nothing documents how each of the 110 requirements is actually met in your environment, so every buyer question and every audit starts from scratch.
A POA&M that never closes
A nist 800-171 assessment produced a list of gaps, but the open items are operational duties like log review and incident response, and there is no team to run them.
CUI everywhere with no boundary
Controlled Unclassified Information sits in email, file shares, engineering drives, and personal devices, so the in-scope system boundary is undefined and the control set becomes unbounded.
Primes auditing their supply chain
Prime contractors now flow requirements down and ask for evidence, not assurances. Without artifacts, logs, and a current SSP, you look like the weak link in their supply chain.
How eMazzanti Delivers NIST 800-171 Compliance
Our nist 800-171 consulting does not stop at a score. We implement the 110 controls and then operate the ones that never stand still, combining 4x Microsoft Solutions Partner expertise in Azure Infrastructure and Data & AI, WatchGuard Founding Partner and 5x Partner of the Year network security, and the 24/7 eCare SOC, all delivered through e365 with 25+ years of managed IT behind it.
Define the CUI boundary and scope
We trace where Controlled Unclassified Information is created, stored, and transmitted, then draw a defensible system boundary so only in-scope systems carry the 110 requirements.
NIST 800-171 assessment and gap analysis
We score all 110 requirements across the 14 control families using the DoD self assessment methodology, so your nist 800-171 gap analysis produces a defensible SPRS score instead of a guess.
System Security Plan and a realistic POA&M
We author the SSP that documents how each requirement is met and a Plan of Action and Milestones with owners and dates you can actually hit, the artifacts primes and auditors ask for first.
Implement the technical control families
As a 4x Microsoft Solutions Partner we build access control, identification and authentication with MFA, configuration management, and media protection on Microsoft 365, GCC, and Azure, with WatchGuard covering system and communications protection.
Operate the continuous families 24/7
Audit and accountability, incident response, and system monitoring cannot live in a spreadsheet, so our eCare services and 24/7 SOC run them, with eCare Cloud Backup satisfying media protection and recovery.
Maintain your score and prepare for CMMC
We reassess periodically, update SPRS, and keep evidence current, which is also the groundwork for certification under our CMMC compliance consulting . If you also carry SOC 2 or health data obligations, we align the same controls with our SOC 2 compliance services and HIPAA compliant IT services .
“We had an assessment from another firm and a POA&M nobody could close. eMazzanti implemented the controls, wrote the System Security Plan, and now operates the monitoring and incident response pieces for us, so our SPRS score is real and it stays that way.”
NIST 800-171 Compliance: Common Questions
What is NIST 800-171?
NIST Special Publication 800-171 is the federal standard that defines 110 security requirements, grouped into 14 control families, for protecting Controlled Unclassified Information when it lives in nonfederal systems. Department of Defense contractors and subcontractors are typically required to meet it through DFARS 252.204-7012, and they document their status in a System Security Plan supported by a Plan of Action and Milestones.
How is NIST 800-171 different from CMMC?
NIST 800-171 is the control standard, the 110 requirements you implement and document. CMMC is the Department of Defense program that verifies you actually did it, with levels, contract eligibility, and third party assessment by a C3PAO. In practice the controls on this page are the substance, and CMMC is the verification wrapper around them, so most contractors implement 800-171 first. For levels, certification, and assessor readiness, see our CMMC compliance consulting page.
What is an SPRS score and how is it calculated?
SPRS is the Supplier Performance Risk System, the Department of Defense portal where contractors post the result of their NIST 800-171 self assessment. The DoD methodology starts from a maximum of 110 points, one for each requirement, and deducts a weighted value for every requirement not yet fully implemented, so a score can fall well below zero when significant controls are missing. The score is reported alongside your System Security Plan date and an expected date for closing remaining items.
Do we need a System Security Plan and a POA&M?
Yes. The System Security Plan documents how each of the 110 requirements is met in your environment, and the Plan of Action and Milestones records what is not yet met, who owns it, and when it will be closed. Both are expected artifacts, and they are usually the first things a prime contractor or an assessor asks to see. The common failure is a POA&M full of operational items with no team to run them, which is exactly the part we take over.
How long does NIST 800-171 compliance take?
Scoping the CUI boundary and completing an assessment of all 110 requirements usually takes a few weeks. Closing the gaps depends on how far the environment is from the standard, since some requirements are configuration changes and others need new tooling or a migration to a compliant Microsoft 365 or Azure tenant. Because several control families are continuous by design, compliance is never finished, which is why we operate them for you rather than handing back a report.
