SPRS Score Calculator
Walk through all 110 NIST SP 800-171 Rev 2 controls and get your exact Supplier Performance Risk System score.
What is an SPRS score?
Your SPRS score measures how well your organization implements the 110 security controls in NIST SP 800-171. It ranges from 110 (perfect) to -203 (nothing implemented). The DoD uses this score to evaluate contractor cybersecurity risk.
Every DoD contractor handling CUI must submit their score to the SPRS portal. A higher score means lower risk and better positioning for contract awards.
How this tool works
- 1. You'll review controls one family at a time (14 families)
- 2. For each control, mark it as Implemented, Planned (with POA&M), or Not Implemented
- 3. Get your score, a prioritized remediation plan, and a family-by-family breakdown
