How Office Heroes CMMC Enclave Works
A defined operating model for handling CUI inside your GCC High tenant
Office Heroes CMMC Enclave is designed to give you a controlled place to handle CUI without forcing your entire business into one broad compliance boundary.
The model is straightforward: establish a defined enclave inside a client-dedicated Microsoft 365 GCC High tenant, control who and what is allowed inside that enclave, document where CUI is permitted to exist, and operate the required controls through a standardized managed service model.
The enclave creates a defined place for regulated work
Many organizations struggle because CUI handling spreads informally across users, devices, storage locations, and business systems. That creates a larger, less controlled assessment scope and makes ongoing operations harder to support.
The enclave model is meant to reduce that sprawl.
Instead of treating the entire company as one undifferentiated compliance environment, the enclave creates a clearly defined security domain for the people, systems, services, storage locations, and controls that actually process, store, transmit, or protect CUI.
Build the enclave inside a client-dedicated GCC High tenant
The standard Office Heroes CMMC Enclave model is deployed inside a client-dedicated Microsoft 365 GCC High tenant with logically enforced enclave segmentation.
That means the enclave is built in your environment, not a shared Office Heroes tenant. Identity controls, access restrictions, approved workloads, administrative controls, logging, monitoring, and documentation are all organized around that defined enclave boundary.
This is the standard tenant model for the product: one client-dedicated GCC High tenant with enclave segmentation.
Define where CUI is allowed to exist
A core part of the model is deciding where CUI is permitted to be processed, stored, or transmitted.
That decision drives:
- which assets are in scope
- which users are authorized for regulated work
- which devices are allowed to handle CUI
- which Microsoft 365 or Azure locations are approved for CUI
- which controls and evidence need to be maintained
The enclave is designed so CUI exists only in approved enclave locations documented in the system boundary and supporting documentation.
Apply the operating mode that fits your business
Office Heroes CMMC Enclave is one standardized product with supported operating modes based on where CUI is allowed to exist.
Mode 1: AVD-Only
CUI is permitted only in enclave-authorized Azure Virtual Desktop sessions and approved enclave storage locations. This is the preferred design when you want the smallest and most controlled CUI boundary.
Mode 2: Local-CUI
CUI is permitted on specifically approved, managed endpoints that are brought into the enclave boundary and operated under the required endpoint controls.
Mode 3: Mixed Mode
Some users work with CUI only through cloud desktops, while other specifically approved users and devices are authorized for local CUI handling where operations require it.
The operating mode does not create a different product. It determines how the fixed core standard is applied.
Control access through identity, roles, and approved paths
The enclave is operated through a standardized identity and access control model.
That includes:
- Microsoft Entra ID access control
- MFA enforcement
- Conditional Access enforcement
- approved role and group assignment models
- privileged access separation
- approval-based access provisioning
- formal access review workflows
Access is meant to be controlled based on approved users, approved roles, approved devices where applicable, and approved methods of access into the enclave.
Protect the enclave with a fixed managed baseline
The product is not just a Microsoft licensing decision or a tenant setup exercise. It is a managed operating model with a fixed baseline of controls and services.
The baseline includes:
- identity and access enforcement
- logging and monitoring
- alert handling and review workflows
- endpoint protection
- DNS-layer protection
- backup controls
- administrative controls
- evidence-oriented operational procedures
This fixed baseline is what makes the product repeatable and supportable across client deployments.
Document the boundary, responsibilities, and evidence model
A working enclave is not only technical. It also has to be documented clearly enough to support internal operations and external review.
That includes:
- system boundary definition
- approved CUI locations
- approved users and devices
- shared responsibility assignments
- external connections
- core policies and procedures
- evidence and review workflows
- client-specific implementation details where permitted
The goal is a controlled environment that can be operated consistently and explained clearly.
Clear ownership matters
The enclave model depends on clear ownership between your organization, Office Heroes, and Microsoft.
You decide and approve
You approve users, devices, data classification decisions, site and data ownership, external sharing decisions, and business-impact decisions related to how regulated work is performed.
Office Heroes implements and operates
Office Heroes implements and operates the technical controls, monitoring, backup, reviews, administrative processes, and evidence support workflows that are part of the managed enclave service.
Microsoft provides inherited controls
Microsoft contributes inherited controls within its documented service boundaries, but those inherited controls do not replace your responsibilities or ours.
A simpler boundary is easier to operate and easier to defend
When the enclave is defined properly, the result is a more controlled place for regulated work and a more supportable operating model.
That typically means:
- less CUI sprawl
- clearer scope
- better control over who and what touches CUI
- more consistent administration
- more structured evidence workflows
- a more practical path for small defense contractors operating in GCC High
Designed to support audit-ready operations
Office Heroes CMMC Enclave is designed to support secure, controlled, and assessment-ready operations for CMMC Level 2 environments.
It is not a guarantee of certification. Final outcomes depend on the implemented environment, documented scope, operating discipline, evidence, and assessor review.
