How MX Stacks Up Against the Competition

Meeting NIST 800-171 requires reliable tools. My MX Data delivers controlled access, encrypted workflows, and continuous monitoring to maintain compliance.

It performs strongly in Security & Compliance, File Control, Collaboration, and Government Contract Work.

✅Aligned with NIST 800-171 Requirements - MX uses its ASR methodology to protect Controlled Unclassified Information (CUI) in line with US federal guidelines. ℹ️ What does this mean?ASR (Anonymize, Shard, Restore) anonymizes CUI at upload, divides it into encrypted shards, stores them in separate secure areas, and restores them only for authorised recipients, offering stronger protection than AES-256 alone.

✅Access Control at Multiple Levels - Ensures only cleared personnel can retrieve or view sensitive documents.

✅Full Audit Trail Logging - Captures detailed file event history to demonstrate compliance during inspections or audits.

❌WeTransfer does not meet NIST encryption or access control requirements without external solutions.

❌Google Drive and Dropbox cannot achieve full NIST 800-171 compliance without custom admin and encryption measures.

NIST 800-171 Security

✅Named Account Access Only – All file access is restricted to approved, authenticated accounts to match NIST control requirements.

✅Data Location Control – Store Controlled Unclassified Information (CUI) in a region that meets compliance needs.

🟡Focused Management Tools – Upload, download, and audit exchanges without engaging unnecessary system features.

❌No Continuous File Sync – Secure handoff approach ensures intentional movement instead of constant background replication.

NIST 800-171 File Management

✅Controlled Unclassified Information Transfers – Share CUI in full alignment with NIST 800-171 safeguards, using encryption and monitored access.

✅In-Context Messaging – Exchange updates and clarifications securely alongside the documents they relate to.

✅Custom-Branded Interface – Deliver files and communications through a secure platform that visually matches your organization’s standards.

🟡No Editing in Platform – All document revisions must be completed before uploading for compliant transfer.

NIST 800-171 Collaboration

✅Send Files Without Size Restrictions – Large datasets or technical documents can be shared freely. Google Drive stops uploads at 750GB/day, and WeTransfer free limits at 2GB.

✅Branded, Encrypted Upload Portals – Gather files in line with NIST 800-171 requirements, using secure intake points styled for your business.

❌Not Designed for Archiving – MX is intended for compliant, secure transfers rather than permanent file storage like Dropbox or OneDrive.

How MX Supports NIST 800-171 Compliance

Controlled Unclassified Information needs disciplined handling. MX encrypts every exchange, binds access to named users and records a precise audit trail. Clear proof, steady control, confident teams working at federal pace.

HIPAA
Healthcare contractors handling CUI must stay HIPAA aligned too. MX encrypts patient files and logs movements to cover both requirements.
CCPA
CCPA adds another privacy layer for contractors. MX enforces access control and logs to satisfy consumer data obligations alongside NIST.
SOX
SOX touches contractors providing financial reporting services. MX secures and tracks shared records which satisfies both SOX and NIST requirements.
GLBA
GLBA applies for contractors working in finance. MX encrypts client files and ensures oversight that ticks the box for both standards.
FISMA
FISMA and NIST 800-171 are close cousins. MX secures federal data with encryption, permissions and logs that align with each framework.
FERPA
FERPA overlaps when education contractors handle student CUI. MX encrypts and restricts access which covers both obligations.
ITAR
ITAR and NIST often collide in defense. MX enforces encryption and geo controls which proves restricted data is secure.
CJIS
CJIS can appear in federal justice contracts. MX logs every action, encrypts law enforcement files and ensures compliance is provable.
IRS 1075
IRS 1075 obligations for taxpayer data mesh with NIST controls. MX encrypts and logs tax records to provide evidence for both.
NIST 800-171
NIST 800-171 is the focus. MX encrypts controlled unclassified data, enforces permissions and creates audit ready trails that meet the standard head on.
