As part of Servvian’s commitment to secure SaaS operations, BreakEven PLUS™ has been engineered with practical access control, traceability, and audit-readiness in mind. Our platform aligns operational workflows with the intent of NIST SP 800-171 Access Control (3.1), helping organizations manage who can access what, when, and why.

Role-Based Access Control Built for Real Business Operations

Within BreakEven PLUS™, super users—typically subscriber administrators—can manage access across the platform through a dedicated Access Control Interface. Permissions are structured around business responsibility, reducing unnecessary exposure while making day-to-day operations efficient and accountable.

Why this matters: NIST 800-171 emphasizes limiting system access to authorized users, processes acting on behalf of users, and devices. BreakEven PLUS™ translates that principle into a practical, manageable permission framework for fast-moving SaaS teams.

Employee Management

Grant or restrict the ability to list, create, edit, delete, import, and export employee records based on assigned role.

Customer & Vendor Controls

Support full CRUD-based access and controlled document interactions for customer and vendor data within the platform.

Segmented File Access

Control access to FALIB™, attendance data, and sales reporting areas while maintaining a structured internal file boundary.

Estimates, Reports & Settings

Fine-tune permissions for estimates, exports, invoice formats, work orders, job costing, and additional configuration workflows.

Permissioning with Accountability

Every meaningful permission-controlled action is tied to the user role and captured as an auditable event. This gives subscriber organizations a practical governance layer without adding friction to their workflow.

Built-In Audit Traceability

Access control is only one part of a mature compliance posture. BreakEven PLUS™ also delivers detailed audit logging across financial and operational modules, making it possible to reconstruct events, investigate changes, and support internal or external review requirements.

Each logged event can capture:

  • Timestamp including date and time
  • User identity
  • Affected user when applicable
  • Module or model impacted
  • Action type such as insert, update, or delete
  • IP address
  • User agent and browser/device information
  • Request ID
  • Device ID

This structure supports stronger accountability by making access-related activity visible, reviewable, and attributable.

Field-Level Change Tracking for Financial Integrity

Beyond user actions alone, BreakEven PLUS™ records exactly what changed inside sensitive workflows. When financial settings or reporting values are updated, the platform preserves both the previous state and the new state for clear operational traceability.

Field Old Value New Value
Hourly sell rate 56.89 62.59
Total profits 9607.53 106739.60
Profit fee markup 1.00 11.11
Operational value: Field-level logging makes it easier to validate adjustments, review unusual changes, and support financial governance with a reliable audit trail.

🔎 Compliance-Aligned, Scope-Controlled

While BreakEven PLUS™ is not positioned as a Controlled Unclassified Information (CUI) processing environment, our security architecture reflects operational best practices aligned with federal frameworks such as NIST SP 800-171. These practices emphasize access restriction, least privilege enforcement, and strong audit accountability across the platform.

This design philosophy allows organizations to benefit from strong governance while maintaining clear separation from regulated CUI processing environments.

This approach gives subscribers:

  • Reduced regulatory exposure
  • Clear separation from CUI environments
  • Strong internal governance controls
  • Audit-ready operational discipline

🎯 Why This Matters

For modules handling sensitive operational information — such as FALIB™, Sales Reports, or Estimates tied to federal bids — granular access control is more than a convenience. It becomes a practical compliance requirement.

By embedding NIST-aligned access control principles directly into your estimation and reporting stack, organizations strengthen their operational security posture while preparing for future compliance obligations.

  • Protect Controlled Unclassified Information (CUI)
  • Reduce internal risk through least-privilege access
  • Maintain auditability for potential DFARS or CMMC assessments
✅ Pro Tip for Subscribers

Administrators should periodically review user permissions, especially before enabling export features within reports or FALIB™ modules. BreakEven PLUS™ logs all permission modifications, ensuring full traceability of access changes.

Where Compliance Meets Usability

Security controls only work when they are actually usable. BreakEven PLUS™ was designed so subscriber administrators can manage access without complexity, while leadership teams retain the visibility needed for governance, accountability, and audit support.

  • Controlled access based on role and responsibility
  • Clear traceability for user and system actions
  • Detailed historical visibility into critical business changes
  • A stronger foundation for secure SaaS operations under NIST 800-171 objectives
