Part 2: Can Anyone Else Do It? Comparing RegDOX and Alternative CUI Solutions

Billions of dollars in federal contracts now hinge on one thing: cybersecurity compliance. As federal contractors scramble to meet the rising bar of cybersecurity compliance, the marketplace is flooded with tools claiming to secure Controlled Unclassified Information (CUI). But can any CUI solution match what RegDOX offers in terms of full compliance, integrated usability, and affordability? Let’s look closely at the alternatives and the gaps they leave behind.

The Compliance Landscape: What a CUI Solution Must Deliver

The Department of Defense requires contractors handling CUI to comply with NIST SP 800-171, encompassing 110 security controls across 14 families, including access control, incident response, and system integrity. Under DFARS 252.204-7012, any external cloud provider storing or processing CUI must implement security “equivalent to FedRAMP Moderate.” The upcoming CMMC 2.0 Level 2 will eventually require third-party assessments to verify these safeguards, while Phase 1 self-assessments are set to begin on November 10, 2025.

So, any effective CUI solution must deliver platform-wide compliance, not just secure storage but secure access, usage, auditing, and incident handling.

Microsoft GCC High: A Powerful but Costly CUI Solution

Microsoft’s Office 365 Government Community Cloud High (GCC High) is often cited as a leading CUI solution. Hosted on Microsoft’s DoD-authorized infrastructure, GCC High meets FedRAMP High and supports NIST 800-171 compliance. It includes tools like SharePoint, OneDrive, and Teams, but at a significant cost and with substantial implementation complexity.

To use GCC High, organizations must go through a validation and sponsorship process with Microsoft, provide proof of eligibility, and often hire consultants for implementation. For large primes, this investment may make sense. For small and mid-size contractors, it can be overkill. They end up paying for an enormous platform when all they need is secure file handling, collaboration, and audit control.

Point Solutions: Incomplete CUI Solutions That Leave Gaps

Other companies market encrypted email or secure file storage solutions such as ProtonMail, Tresorit, or Dropbox, with layered-on encryption. Some even offer “zero-knowledge” storage or blockchain-based audit logs. But here’s the catch: these tools only address parts of the problem.

For example, a secure email client does not secure where attachments are stored or prevent users from copying data to unmanaged devices. A secure storage tool can encrypt files but cannot monitor who accessed or edited them or how they were shared. In practice, users must jump between tools, increasing friction and risk. More importantly, these fragmented solutions do not meet FedRAMP Moderate equivalency, which is a requirement under DFARS 7012.

In short, piecemeal offerings may look like affordable CUI solutions, but they fail to provide the unified compliance framework defense contractors actually need.

RegDOX: A Purpose-Built CUI Solution for Compliant Collaboration

RegDOX offers an all-in-one virtual workspace hosted in AWS GovCloud, explicitly designed to meet the requirements of NIST 800-171, NIST 800-172, DFARS, CMMC, and ITAR. Its technical compliance and usability-first approach set it apart from other CUI solutions.

Unlike other options, RegDOX houses the storage and the applications in the same secure cloud instance. Documents are never downloaded to local machines, and users work on them in place. Identity and access controls are unified under a single user account. All activity is logged and auditable in real time. Because it is hosted in GovCloud, it satisfies the “FedRAMP equivalency” language of DFARS 7012 without needing full FedRAMP authorization.

Moreover, RegDOX does not require consultants or a complex setup. It is available out of the box for companies of all sizes, with pricing models accessible to SMBs.

Conclusion: Choosing the Right CUI Solution

When managing CUI in a compliant virtual environment, no provider delivers the same balance of compliance, control, and usability as RegDOX. Microsoft GCC High is powerful but costly and difficult to implement. Point solutions are affordable but fragmented and incomplete.

RegDOX stands alone as a secure, scalable, and truly compliant CUI solution that unifies the entire process from secure storage to in-place document use, from identity management to full auditing, without the downsides. For contractors aiming to meet today’s strict requirements and tomorrow’s evolving standards, it is not just a good choice. It may be the only one.
