Understanding Your Score

The SPRS Score — What It Means

Your SPRS (Supplier Performance Risk System) score is a number between -203 and 110 that represents your NIST 800-171 compliance posture. It starts at 110 points and deducts points for each requirement not fully implemented.

Different requirements have different point values — requirements with higher security impact deduct more points when not met. A score of 110 means all requirements are fully implemented. Most organizations start with a negative score.

Your SPRS score is visible to DoD contracting officers and can affect contract award decisions. Submitting an inaccurate score is a False Claims Act violation.

110Perfect Score

All 110 requirements fully implemented. Rare for organizations starting from scratch.

70–109Strong Posture

Most requirements met. Minor gaps with credible POA&M. Acceptable for most contracts.

1–69Moderate Posture

Significant gaps exist. Active remediation required. May affect contract award.

NegativeSignificant Gaps

Many requirements not met. Immediate remediation required. High contract risk.

Stage-by-Stage Roadmap

The 6-Stage NIST 800-171 Journey

Every NIST 800-171 engagement follows these six stages. Click each stage to see exactly what happens, what it costs, and how much of your team's time it requires.

A comprehensive evaluation of your current security posture against all 110 NIST SP 800-171 requirements across 14 control families. The assessment uses the NIST 800-171A assessment methodology to produce a scored baseline — the same methodology used by C3PAO assessors for CMMC Level 2.

What Happens in This Stage

  • Kick-off with IT, security, HR, facilities, and leadership
  • CUI scoping — identify every system, cloud service, and process that touches CUI
  • CUI data flow mapping and system boundary definition
  • Review of all existing policies, procedures, and technical controls
  • Technical interviews with system administrators and IT staff
  • Vulnerability scan of in-scope systems
  • Review of existing SSP and POA&M (if any)
  • Scoring of all 110 requirements using NIST 800-171A methodology
  • Delivery of scored GAP report with prioritized findings

Stage Outputs

  • GAP Assessment Report (110-requirement scoring)
  • CUI data flow diagram
  • System boundary definition
  • Prioritized remediation roadmap

Small Business Reality

The CUI scoping exercise is often the most eye-opening part of the GAP assessment — organizations frequently discover CUI in places they didn't expect (email archives, cloud storage, backup systems). For a small business, expect 12–20 hours of your team's time across the 3–4 week assessment.
