Managed CUI boundary

DefenseStack helps teams handle CUI with less operational drag

DefenseStack provides a managed secure boundary for CUI workflows, documentation, evidence, and compliance support so contractors can focus on execution instead of building every control from scratch.

Who it is for

  • Defense contractors and subcontractors
  • Organizations handling Controlled Unclassified Information
  • Small teams pursuing CUI-enabled contracts
  • Prime contractors needing subcontractor compliance support

Problem

CUI work creates audit, documentation, endpoint, access, and monitoring obligations that can overwhelm lean contractors.

A managed boundary for CUI workflows

DefenseStack is the current Delphius Beacon brand for managed CUI work. The offering focuses on reducing exposure, maintaining evidence, and supporting CMMC-aligned operations.

  • Scope where CUI is received, stored, shared, and supported
  • Separate CUI workflows from broad corporate IT where appropriate
  • Maintain access, documentation, and evidence around the boundary
  • Support users without forcing every control into a generic MSP model

Where CUI lives inside the managed boundary

The DefenseStack operating model keeps CUI inside a managed boundary while allowing authorized users to work through controlled access paths.

  • Users access CUI through controlled browser or managed endpoint workflows
  • CUI stays out of local device storage where appropriate
  • Secure email, file storage, collaboration, evidence, and policy materials sit inside the managed layer
  • Underlying compliant infrastructure supports identity, MFA, logging, and monitoring
