ITAR + CMMC Compliance for Defense Manufacturers
If you manufacture defense articles or handle ITAR-controlled technical data, you are dealing with two compliance obligations at the same time: ITAR under the State Department and CMMC under the DoD. Most consultants treat these as separate problems. They are not.
The CUI you handle IS your ITAR-controlled technical data. The environment you build for CMMC is the same environment that protects your ITAR obligations. The GCC High tenant you need for one is the GCC High tenant you need for the other. Two regulatory frameworks, one technical solution.
We help small defense manufacturers build a single compliance program that satisfies both ITAR and CMMC Level 2. One project, one environment, both obligations met. No duplication, no wasted spend, no running the same exercise twice with two different consultants.
Why ITAR and CMMC Overlap for Manufacturers
This is where most manufacturers get confused, so let's walk through it in plain terms.
When the DoD sends you a contract that involves technical drawings, specifications, or manufacturing data, that information is almost always classified as Controlled Unclassified Information -- CUI. Specifically, it falls into a CUI category called Controlled Technical Information, or CTI. CTI is a formal designation that means this technical data requires protection under NIST 800-171 controls.
Now here's the overlap: if that technical data relates to defense articles on the United States Munitions List, it is also ITAR-controlled. That means the same set of engineering drawings sitting on your file server is simultaneously CUI (requiring CMMC Level 2 protection) and ITAR-controlled (requiring export control restrictions). Two labels, same data, same files.
CMMC Level 2 protects that data through the 110 security controls in NIST 800-171. ITAR requires that the data only be accessible to U.S. persons -- no foreign nationals, no overseas datacenters, no cloud infrastructure operated by non-U.S. personnel.
This is exactly why Microsoft 365 GCC High exists. GCC High runs in U.S.-only datacenters, operated exclusively by screened U.S. persons. It is FedRAMP High authorized. That means it satisfies ITAR's access control requirements AND provides the compliant infrastructure foundation for CMMC Level 2. One platform, both obligations addressed.
What This Means for Your Shop
Let's make this concrete. If you run a machine shop or manufacturing operation working on defense contracts, here is what this overlap looks like in your day-to-day:
Your data is probably both CUI and ITAR-controlled
Engineering drawings, material specifications, manufacturing process data, test results -- if they relate to items on the Munitions List, they carry both designations. You do not need two separate handling procedures. You need one environment that satisfies both requirements.
Email, files, and collaboration need U.S. persons-only access
Every email with a technical data package attached, every SharePoint folder with controlled drawings, every Teams conversation discussing contract specifications -- all of it needs to live in an environment where only U.S. persons can access the underlying infrastructure. Commercial Microsoft 365 does not meet this requirement. GCC High does.
GCC High handles both obligations natively
Microsoft 365 GCC High provides U.S. person-only datacenters (ITAR requirement), FedRAMP High authorization (CMMC infrastructure requirement), and the security controls needed to protect CUI. You are not installing two separate systems. One platform covers the infrastructure needs for both frameworks.
Your CMMC enclave IS your ITAR-controlled environment
The enclave you build to limit CMMC scope -- the segmented environment where CUI is handled by authorized users on hardened devices -- is the same controlled environment that satisfies ITAR access restrictions. One boundary, one set of users, one set of policies. Built once, serving both purposes.
The bottom line: if someone is telling you that ITAR compliance and CMMC compliance are two separate projects requiring two separate budgets, they are either doing it wrong or billing you twice. The work converges. The environment converges. The project should converge too.
Our Approach: Integrated Compliance, Not Two Separate Engagements
We do not run an ITAR project and then come back for a CMMC project. We scope both obligations from the start and build one environment that covers everything. Here is what that looks like:
Scope Assessment Covering Both Obligations
We map your ITAR data flows and your CUI handling together. Where does controlled technical data enter your organization? Who touches it? Where does it get stored, processed, and transmitted? Which of your contracts involve USML items? This assessment defines the boundary for both ITAR and CMMC in a single exercise.
Single Enclave Design
We architect one enclave that satisfies CMMC Level 2 security controls and ITAR access restrictions simultaneously. The boundary is defined once. The access policies address both frameworks. The network segmentation serves both purposes. No duplication.
GCC High Migration with ITAR Access Restrictions
We migrate your enclave users to GCC High and configure ITAR-specific access controls from day one. U.S. person verification, data residency enforcement, and export control-aware sharing policies are built into the tenant configuration -- not bolted on after the fact.
Policies and Procedures Addressing Both Frameworks
Your access control policy does not just address NIST 800-171 requirements -- it also documents your ITAR access restrictions. Your data handling procedures cover CUI marking AND export control classification. One set of documents that your team actually follows, covering both obligations without contradiction or overlap.
SSP Documenting ITAR Data Within the CMMC Boundary
Your System Security Plan describes how CUI is handled in your environment. We write it to explicitly address ITAR-controlled technical data as a CUI category within your CMMC boundary. When your assessor reads your SSP, they see a complete picture. When your ITAR compliance is reviewed, the same documentation supports it.
The result is one compliance program that you can point to for both obligations. Not two binders, not two projects, not two sets of consultants asking the same questions. One integrated approach that costs less, takes less time, and is easier for your team to actually follow.
