CUI and below

Not everything sensitive is classified.

A great deal of government and defense-industrial mobility handles data that matters enormously and is not classified — Controlled Unclassified Information, export-controlled technical data, law enforcement sensitive, critical infrastructure. The requirements are real, they are narrower than CSfC, and getting the distinction right saves programs a great deal of money.

Where Programs Go Wrong

Two opposite mistakes, both expensive.

OVER

Building toward CSfC when you did not need to

A program hears "sensitive data on phones," reaches for the framework it has heard of, and starts scoping two VPN vendors, two certificate authorities and a registration package — for data that never required any of it. The result is a budget that does not survive review and a timeline measured in years instead of months.

UNDER

Assuming unclassified means unregulated

The opposite failure. CUI carries real obligations — a mandatory STIG baseline on DoD networks, FIPS-validated cryptography, enforced device management, documented exceptions. Teams that treat "not classified" as "not governed" discover otherwise at assessment, with a fleet already deployed.

The clarifying question

What is the actual classification of the data, in writing, from the authority that owns it? Not what someone assumes, not what the worst case might be. That single answer determines whether you are on this page or the classified one — and it is worth pinning down before a single product is evaluated.

What Actually Applies

Narrower than CSfC. Not nothing.

The building blocks are the same components CSfC draws on — you simply need fewer of them, and you do not register a solution.

DISA STIG
Applies. Published mobile STIGs are explicitly scoped to unclassified data up to CUI, for corporate-owned deployments. This is your configuration baseline and your evidence at assessment.
NIAP validation
Applies. The device should be validated against the Mobile Device Fundamentals Protection Profile. Listing on the CSfC Components List is not required.
FIPS 140 cryptography
Applies. Federal use of cryptography for sensitive information requires CMVP-validated modules. Watch for certificates marked Historical.
Mobile device management
Applies. You need enforcement, not just policy on paper. Any capable UEM works — the single-product CSfC constraint does not bind here.
Two independent encryption layers
Does not apply. One properly validated layer, correctly configured, is the requirement. This is the largest single cost difference.
CSfC Components List
Does not apply. Which is why your platform options widen considerably — see below.
Solution registration with NSA
Does not apply. You accredit through your own process with your Authorizing Official.
Getting It Right

Build your baseline, step by step.

Answer the questions and this narrows to the STIG you actually need and the OS-control mechanism your platform actually has. The differences are larger than most teams expect — one of these combinations cannot pin an OS version at all.

01

Get the data classification in writing

From the authority that owns the data. Everything downstream depends on it, and an assumption here is the most expensive kind of mistake available.

02

Pick your device

Platform, then manufacturer, then how it is enrolled. Enrollment mode decides more about what you can enforce than the hardware does.

03

Does it need FedRAMP or GovRAMP authorization?

Answer this before you shortlist anything. It eliminates more products than any other question here — and it decides which ones are even eligible to appear in the next step.

04

Pick your UEM/MDM

Grouped by the two authorizations that matter for federal use: NIAP validation against the Mobile Device Management Protection Profile, and FedRAMP authorization for the cloud service.

05

Pick your STIG

COBO and COPE ship as separate benchmarks, and BYOAD is a different STIG entirely. Loading the wrong one produces a clean checklist against the wrong requirements.

Choose a platform and deployment type to see which benchmark applies.

06

Control OS versions from day one

STIGs are versioned to OS releases. An uncontrolled update moves devices off your baseline — and can equally strand them on an unpatched build. What you can actually do about that varies sharply by platform.

Choose a platform to see the mechanism available to you.

07

Document every exception with its justification

Findings you cannot meet are normal and expected. Findings you cannot explain are what turn an assessment into a finding of your own.
