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
