If your engineering team touches Department of Defense or federal work, compliance has quietly become a condition of getting paid. CMMC now gates DoD contracts. FedRAMP governs the cloud services federal agencies are allowed to use. Both are enforceable, both flow down to subcontractors, and both were written by cybersecurity policymakers who were not thinking about a 4 GB SOLIDWORKS assembly opening across a GPU workstation. That gap — between how these frameworks are written and how engineering actually works — is where most teams get stuck.
Here's the plain-English version of what CMMC and FedRAMP require, the challenges that make them uniquely painful for CAD and PDM driven organizations, and how EpiGrid's compliance-ready hosting lets you inherit a hardened foundation instead of building one from scratch.
What CMMC Actually Requires
The Cybersecurity Maturity Model Certification (CMMC) is the Department of Defense's mechanism for verifying that companies in the defense industrial base actually protect sensitive government information — rather than just promising to. The program rule took effect December 16, 2024, and the DFARS acquisition rule that puts CMMC into contracts followed on November 10, 2025.
The first thing to understand is what kind of data you handle, because that sets your level:
- FCI (Federal Contract Information) — information provided by or generated for the government under a contract that isn't intended for public release.
- CUI (Controlled Unclassified Information) — government information that law or policy requires you to safeguard. For engineering teams, CUI frequently lives inside your design data: controlled drawings, models, specifications, and technical data packages.
FCI — basic safeguarding. 15 requirements from FAR 52.204-21. Annual self-assessment; no third party required.
CUI — the level most engineering firms land on. The full 110 controls of NIST SP 800-171. For most CUI contracts this requires a C3PAO third-party assessment, valid for three years with annual affirmations.
High-value CUI under advanced-threat risk. All Level 2 controls plus a subset of NIST SP 800-172 enhancements, assessed by the government's DIBCAC.
The rollout is phased, and the clock is already running. As of November 2025, DoD can condition awards on Level 1 and Level 2 self-assessments. Beginning November 2026, it can require the Level 2 C3PAO assessment — the harder, third-party bar. By 2028, CMMC clauses become mandatory across applicable DoD contracts. Critically, these requirements flow down the supply chain to subcontractors at every tier. If you make parts for a prime, "we're just a sub" is not an exemption.
What FedRAMP Actually Requires
FedRAMP (the Federal Risk and Authorization Management Program) does for cloud services what CMMC does for contractors: it standardizes how a cloud environment is security-assessed so federal agencies can trust it. If your work is hosted, the environment it runs in increasingly needs to meet a FedRAMP baseline — and those baselines are built on the NIST SP 800-53 control catalog, sized to how much damage a breach would cause:
- Low — limited impact. Roughly 156 controls. Public-facing, low-sensitivity systems.
- Moderate — serious impact. Roughly 323 controls. This is where most CUI lands, which is why it's the baseline that matters for defense-adjacent engineering data.
- High — severe or catastrophic impact. Roughly 410 controls. Law enforcement, emergency services, and the most sensitive non-classified national-security data.
Authorization has historically come through a sponsoring agency (an Agency ATO), and authorized services typically live in hardened government-community cloud regions — AWS GovCloud, Azure Government, and equivalents — that are physically and logically separated from commercial infrastructure. FedRAMP is also modernizing: the FedRAMP 20x initiative is pushing the program toward automation-first, continuously monitored authorizations rather than slow, point-in-time paperwork. The direction of travel is clear — continuous proof of security, not an annual snapshot.
Why These Frameworks Are Uniquely Hard for Engineering Teams
Plenty of vendors will sell you a "compliant" mailbox or a secure document portal. Engineering is a different animal, and this is where the standard playbook breaks down:
- Your CUI hides inside your CAD and PDM data. Controlled technical data isn't a tidy folder of PDFs — it's embedded in native models, drawings, and the PDM vault itself. That means the vault becomes part of your compliance boundary, and scoping it correctly is genuinely hard.
- Performance and security pull in opposite directions. SOLIDWORKS and PDM are latency-sensitive, GPU-hungry, and large-file heavy. Bolt on generic secure-cloud controls without engineering-aware architecture and you get compliant-but-unusable — which is how shadow IT and workarounds (the real breach risk) get born.
- Shared responsibility is widely misunderstood. A cloud provider secures the infrastructure of the cloud; you remain responsible for what happens in it. Teams routinely assume "hosted" means "compliant," discover the gap during an assessment, and scramble.
- The control set is broad and specialized. FIPS-validated encryption, granular access control, audit logging, incident response, continuous monitoring, a security operations capability — most SMB manufacturers simply don't have that expertise on staff.
- The deadlines are external. Your prime's flow-down clause and the November 2026 C3PAO gate don't wait for you to hire a CISO or stand up a SOC.
The trap: most engineering teams try to retrofit compliance onto infrastructure that was never designed for it — a general-purpose cloud VM, an on-prem server nobody has patched, or a hosting provider with no CAD or defense context. Every retrofit widens your compliance boundary, your cost, and your risk.
How EpiGrid Closes the Gap
EpiGrid has built engineering cloud infrastructure — and nothing else — since 2011. That focus is the point: the hosting is architected around how SOLIDWORKS, PDM, and virtual CAD workstations actually behave, and it's built to be compliance-ready rather than compliance-retrofitted.
In EpiGrid's own words, its infrastructure solutions are compliance-ready for HIPAA, PCI, FISMA (NIST 800-53), GDPR, DoD CUI controls (NIST 800-171), and Privacy Shield, and EpiGrid can architect solutions for clients that need FedRAMP, SOX, and/or ISO 27001 compliance. Translated for an engineering leader, that means:
- You inherit controls instead of building them. EpiGrid owns the hardening, patching, monitoring, and data-center security of the cloud — the layer that maps to a large share of your NIST 800-171 and 800-53 obligations — so your team's remaining scope is smaller and more defensible going into an assessment.
- Shared responsibility is drawn clearly, up front. You know exactly which controls EpiGrid carries and which stay with you — no assessment-day surprises.
- Security doesn't cost you performance. Because the platform is engineered for CAD and PDM workloads, the controls sit on top of infrastructure that keeps engineers productive — not one that forces the workarounds compliance is supposed to prevent.
- Solutions are architected to your requirement. Whether you're targeting NIST 800-171 for CMMC Level 2 or a FedRAMP-aligned environment, EpiGrid designs the hosting to fit your specific obligation and your prime's flow-down.
