Best USB Security for CMMC Compliance

Eliminate USB Malware Threats to Accelerate CMMC Readiness

Defense and aerospace contractors can’t always remove USB devices from Controlled Unclassified Information (CUI) workflows. TYREX Decontamination Stations scan and remove malware from removable devices before they reach sensitive systems, giving contractors a USB security and documentation solution that supports CMMC compliance.

USB Devices Evade Network and Endpoint Protections

Defense contractors who handle CUI must meet CMMC requirements and implement the relevant NIST SP 800-171 controls. Uncontrolled USB devices can introduce malware capable of exfiltrating CUI, exposing contractors to financial and regulatory penalties.

Port Blocking Does Not Work for Every CUI Workflow

USB port blocking is useful when removable media has no business purpose, but many defense contractors cannot apply a blanket restriction across every system. They need an effective way to scan and decontaminate USB devices prior to connection.

Uncontrolled USB Use Can Put SPRS Points at Risk

Removable media impacts nine CMMC Level 2 controls with a combined Supplier Performance Risk System (SPRS) weight of 39 points. Organizations that fail to control the risks posed by removable media are exposed to adverse CMMC assessment outcomes.

CMMC Compliance Is a Contract Requirement

Removable media security gaps affect your organization’s ability to compete for covered contracts. The CMMC Final Rule makes CUI cybersecurity a compliance prerequisite for many defense industrial base contracts that involve CUI handling.

Assessors Need Evidence That USB Controls Are Enforced

Assessors expect records that show USB controls are enforced and repeatable. The evidence should make it clear that technical controls detect and eliminate malware as removable media enters the environment.

Inadequate Removable Media Controls Can Delay CMMC Assessments

Defense contractors must address removable media malware risk. For CMMC Level 2, removable media gaps can affect controls in several NIST SP 800-171 families. If those controls are scored as not met, your organization may lose points that cannot be deferred through a Plan of Action and Milestones (POA&M).

  • Control the use of removable media.
  • Provide malware protection when USB files enter the environment.
  • Check maintenance and diagnostic media before use.
  • Maintain evidence for media protection, accountability, and audit trails.

Streamline CMMC Compliance With TYREX

TYREX Decontamination Stations provide a scan-before-connect control point for removable media. Your organization can route authorized USB activity through a dedicated USB scanning kiosk at the point where files enter the environment.

Scan and Clean Removable Media

TYREX stations scan removable media with up to five simultaneous antivirus engines and two antimalware engines that use artificial intelligence, including Airbus Orion and Glimps. BadUSB detection adds protection against firmware-level attacks.

Control Authorized USB Use

Compliance teams gain a governed pathway for USB use. That pathway supports compliance when your organization cannot remove removable media from the workflow but needs a consistent way to approve each device and account for inspection activity.

Certify Scanned Devices

After analysis, TYREX can issue a time-limited certificate to a cleared device. Workstation Protect Agent extends protection to endpoints by blocking uncertified USB devices or files.

Secure USB File Transfers

TYREX creates a documented checkpoint where files can be inspected and cleared before transfer, with activity logged for review. Teams can move validated files to network shares or USB devices without bypassing the USB security process.

Document USB Activity

TYREX Management Server collects scan and connection data from multiple decontamination stations. Documentation provides clear insight into how removable media is handled and secured across your organization.

Manage Distributed Controls

CMMC compliance depends on consistent USB controls across every location where removable media is used. TYREX Management Server helps security teams apply station policies and monitor activity across deployed stations.

Take Control of USB Security and CMMC Compliance With TYREX

If your CUI environment still relies on USB devices, TYREX can help your team replace informal removable media exceptions with a controlled and auditable process.

CMMC Compliance FAQ

What Role Does USB Security Play in CMMC Level 1 Compliance?

USB decontamination supports CMMC Level 1 compliance by reducing the risk of malware infection and accidental exposure of Federal Contract Information. Rigorous USB procedures tell staff when removable media is permitted and how it must be checked before use.

CMMC Level 2 treats removable media as part of a wider control environment under NIST SP 800-171. USB security policies determine how an organization keeps malicious files away from protected systems, restricts unnecessary endpoint access, handles maintenance media, and produces audit records.

In some cases, contractors can block USB ports where removable media is not required. However, others need USB because specific operational workflows depend on physical media. Those exceptions need governed technical controls so the organization can show how approved use is limited and inspected.

TYREX stations can be rapidly deployed as dedicated USB security checkpoints within existing workflows. Organizations can begin governing removable media activity while CMMC documentation and assessment preparation continue, which helps close a common gap before assessment.
