Why Your SPRS Score Matters More Than Ever
If you are a defense contractor handling Controlled Unclassified Information, your Supplier Performance Risk System score is no longer a background metric. Contracting officers are actively reviewing SPRS scores during source selection, and a score deep in negative territory can quietly cost you work before you ever receive a declination notice. The stakes have only increased as the DoD has accelerated its cybersecurity enforcement posture and as CMMC 2.0 draws closer to full contractual enforcement.
The good news is that SPRS score improvement is achievable on a structured timeline. The bad news is that many contractors attempt it without a clear plan, over-score themselves to avoid embarrassment, or treat their Plan of Action and Milestones as a paperwork exercise rather than a genuine remediation driver. This roadmap is designed to help compliance managers and executives move from wherever they are today to a defensible, assessment-ready posture.
For background on how the scoring methodology works and how contracting officers interpret the numbers, see our post on understanding SPRS cybersecurity assessments for defense contractors.
Understanding Where Negative Scores Come From
The NIST SP 800-171 self-assessment scoring methodology assigns point values to each of the 110 security requirements across 14 control families. A perfect implementation earns a score of 110. Every unimplemented or partially implemented control carries a negative point value, with high-weighted controls deducting significantly more than lower-weighted ones. When contractors have not implemented foundational controls—multi-factor authentication, audit logging, access control policies, incident response procedures—the score can drop well below zero.
Negative SPRS scores are common among small and mid-sized contractors who have grown their businesses on the technical side without proportional investment in their security infrastructure. They are not a mark of bad faith. They are, however, a contractual liability that must be addressed systematically.
Common root causes of deeply negative scores include:
- No formal System Security Plan documenting the environment and control implementation status
- Absent or informal access control and user authentication practices
- Undocumented incident response and media protection procedures
- No audit logging or log review processes in place
- Unmanaged use of portable media and personal devices
- Missing configuration management baselines for endpoints and servers
- No formal risk assessment process or awareness training program
Our post on SSP and POA&M as critical components of a strong security program explains why these two documents are the foundation of any credible improvement effort.
Phase One: Establish Your Honest Baseline
Before you can improve your score, you need to know your real score. This sounds obvious, but it is where many contractors stumble. Inflating a self-assessment to avoid a painful number creates False Claims Act exposure and sets up a harder conversation with assessors later. An honest, documented baseline is a legal and strategic necessity.
Start by conducting a gap assessment against all 110 NIST SP 800-171 controls. Document the evidence—or lack of evidence—for each control. For controls that are not implemented, capture why, what the risk is, and a realistic timeline for remediation. For controls that are partially implemented, note specifically what is missing.
This work feeds two critical artifacts: your System Security Plan and your Plan of Action and Milestones. The SSP describes your environment and how each control is addressed. The POA&M captures what is not yet implemented, with milestones, responsible parties, and target completion dates. Together, these documents are what a DIBCAC assessor or a contracting officer will want to see when they evaluate whether your self-assessment score is credible.
Our Federal and SLED risk assessment services are structured specifically to produce this kind of defensible baseline documentation for contractors in the DoD supply chain.
Phase Two: Prioritize Remediation by Score Impact and Risk
Not all 110 controls carry equal weight. The NIST SP 800-171 DoD Assessment Methodology assigns values of one, three, or five points to individual requirements. Controls worth five points should drive your near-term remediation priorities, not only because they will move your score the most but also because they typically represent the highest-risk gaps in your environment.
High-impact areas where contractors frequently recover the most points in the shortest time include:
- Access Control (AC): Implementing role-based access, enforcing least privilege, and deploying multi-factor authentication for CUI systems and remote access can recover significant points quickly.
- Identification and Authentication (IA): MFA enforcement, password complexity policies, and managing authenticators are often only partially implemented and can be addressed with existing tools.
- Audit and Accountability (AU): Enabling audit logging on endpoints, servers, and cloud environments and establishing a log review process addresses multiple controls simultaneously.
- Configuration Management (CM): Establishing and documenting baseline configurations, controlling software installation, and managing security settings across the environment addresses a cluster of high-value controls.
- Incident Response (IR): Developing, documenting, and testing an incident response plan with defined roles and reporting procedures addresses multiple requirements at once.

Phase Three: Execute Remediation in Structured Sprints
Remediation without a project management structure tends to stall. Assign ownership for each POA&M item to a specific individual, establish 30-, 60-, and 90-day milestones, and hold recurring status reviews. For small contractors without in-house security leadership, a Regulatory vCISO can provide the ongoing oversight needed to drive remediation to completion rather than letting it drift.
Keep your SPRS score updated in the Supplier Performance Risk System each time you complete a meaningful set of remediations. DoD policy requires that scores be updated within 30 days of material changes. Keeping your score current and trending upward signals good faith to contracting officers and demonstrates active program management.
Document everything as you go. Evidence collected during remediation—configuration screenshots, policy approval records, training completion logs, MFA enrollment records—becomes the audit trail that supports your self-assessment score. Assessors do not accept assertions. They verify evidence. Collecting it in real time is far more efficient than reconstructing it before an assessment.
Phase Four: Address Documentation and Policy Completeness
A significant portion of NIST SP 800-171 controls require documented policies and procedures, not just technical implementations. Contractors who focus exclusively on technical controls and neglect documentation often leave recoverable points on the table. Policy development should run parallel to technical remediation, not after it.
Required policy areas include but are not limited to:
- Access control and account management policies
- System and communications protection policies
- Media protection and sanitization procedures
- Personnel security and training requirements
- Physical protection policies for CUI processing areas
- Risk assessment and security assessment procedures
- Maintenance and configuration management policies
Our CMMC, CUI, and DFARS compliance services include policy development support aligned to both NIST SP 800-171 and CMMC Level 2 requirements, which are derived from the same 110-control set.
Phase Five: Validate Before You Submit
Before updating your SPRS score following a major remediation effort, conduct an internal validation review. Walk through each control you are claiming as implemented and confirm that the supporting evidence is available, current, and complete. Identify any controls where implementation has been completed but documentation has not caught up. Resolve those gaps before submission.
If your contracts or anticipated contracts include DIBCAC assessment risk, consider engaging a third party to conduct an independent readiness review before you finalize your score. This is distinct from a formal C3PAO assessment—it is a structured review designed to identify scoring inconsistencies, documentation weaknesses, and control gaps that a DIBCAC team would flag. Investing in this step before submission significantly reduces the risk of a score correction demand or a formal finding during a government-initiated review.
Our post on conducting a defensible NIST 800-171 self-assessment covers the specific practices that distinguish a credible submission from one that will not survive scrutiny.
Common Mistakes That Stall SPRS Score Improvement
In our work with defense contractors across the industrial base, we consistently see the same patterns derail improvement efforts:
- Treating the SSP as a one-time document rather than a living record that reflects the current state of the environment
- Assigning POA&M items without accountable owners or realistic resource allocation, leading to items that age without progress
- Scoring controls as implemented based on intent rather than demonstrated, evidenced practice
- Neglecting cloud and third-party system boundaries that are in scope for CUI processing but excluded from the assessment
- Failing to update the SPRS score as remediations are completed, leaving a stale negative score on record longer than necessary
For additional context on how to avoid inflated scores that create downstream legal and contractual risk, see our post on self-assessment errors that result in inflated SPRS scores.
How Long Does SPRS Score Improvement Take?
There is no universal answer, but contractors who approach remediation with structured project management, adequate resources, and experienced guidance typically see meaningful score improvements within 90 to 180 days. Reaching a score in the 80 to 110 range from deeply negative territory often requires 12 to 18 months of sustained effort, particularly when significant infrastructure investments or cloud migration are part of the remediation plan.
The trajectory matters as much as the current number. A contractor with a score of negative 47 and a detailed POA&M with documented progress is in a substantially stronger position than one with a score of 30 and no evidence of active program management.
