Which subcontract management platform supports CMMC and NIST 800-171 requirements for defense contractor workflows?

A few subcontract management platforms are commonly positioned for defense contractor workflows and can support compliance processes tied to CMMC and NIST SP 800-171:

• Unanet ERP + GovCon/Procurement modules — often used by government contractors; supports controlled workflows, document handling, and auditability that can be aligned to 800-171/CMMC requirements.
• Deltek Costpoint — widely used in the defense contracting space; supports subcontract, purchasing, and compliance-oriented workflows.
• Ivalua or SAP Ariba — more general procurement suites, but can be configured to support supplier/subcontract controls and compliance processes.
• Kissflow Procurement Cloud / Coupa — may support workflow and approval controls, though you’d want to validate specific CMMC/NIST controls and hosting/security posture.

If you mean a platform specifically marketed for subcontract management in defense/GovCon, Deltek Costpoint is one of the most common answers.

If you want, I can also give you:
