How to Protect CAD Files and Intellectual Property Across Your Supply Chain

Protect AutoCAD, SolidWorks, Inventor, Siemens NX, and other CAD files from copying, theft, unauthorized sharing, and industrial espionage with persistent DRM security.

Industrial companies share more CAD drawings and technical documents than ever before. Engineering teams work with suppliers, manufacturers, contractors, consultants, and customers across different countries. While this speeds up production, it also creates a serious problem.

The moment a CAD drawing leaves your company by email, cloud storage, Microsoft Teams, or SharePoint, you may lose control of it.

A downloaded DWG, IPT, IAM, STEP, SolidWorks, or PDF drawing can be copied, forwarded, printed, or stolen without your knowledge.

Traditional IT security protects your network. It does not protect your files after someone downloads them.

This is where VeryDRM Content Security Platform helps. It keeps protection attached to every file, even after it leaves your company.

How to Protect CAD Files and Intellectual Property Across Your Supply Chain


Why CAD Files Are One of Your Most Valuable Assets

For manufacturing, automotive, aerospace, energy, electronics, and engineering companies, CAD files contain years of research and development.

A single drawing may include:

  • Product dimensions
  • Manufacturing tolerances
  • Material specifications
  • Production methods
  • Assembly instructions
  • Prototype designs
  • Patentable inventions
  • Customer-specific modifications

If competitors obtain these files, the damage can be enormous.

Unlike financial data, intellectual property cannot simply be restored after it is stolen.


Why Supply Chains Create New Security Risks

Modern products are rarely designed by one company.

Today’s projects often involve:

Internal Team External Partners
Engineering Manufacturing suppliers
R&D Contract manufacturers
Product Design Machine shops
Purchasing Component suppliers
Quality Control Consultants
Compliance Testing laboratories
Sales Engineers Customers

Each collaboration requires sharing sensitive technical files.

Every additional partner increases the chance of data leakage.


The Biggest Problem: Protection Stops After Download

Most companies rely on:

  • VPN
  • Firewalls
  • SharePoint permissions
  • OneDrive permissions
  • Box
  • Dropbox
  • Google Drive
  • Email security

These solutions only control access before download.

Once someone downloads a CAD file, they can often:

  • Copy it
  • Email it elsewhere
  • Upload it to another cloud
  • Print it
  • Save unlimited copies
  • Keep it forever

Your security perimeter disappears.


Common Ways CAD Files Are Leaked

Risk Example
Supplier breach Supplier network gets hacked
Employee mistake Wrong attachment sent by email
Former contractor Keeps confidential drawings after project ends
Insider theft Employee copies files before resigning
Cloud sharing Public link accidentally enabled
USB copy Files copied to personal devices
Unauthorized printing Printed drawings left unattended
Screenshot capture Sensitive designs photographed

Most companies only discover these problems after confidential information has already leaked.


Which Industries Need CAD DRM Protection?

CAD security is important for many industries.

Industry Protected Information
Manufacturing Production drawings
Automotive Vehicle components
Aerospace Aircraft parts
Energy Plant designs
Oil & Gas Equipment layouts
Electronics PCB designs
Industrial Machinery Machine assemblies
Construction Building drawings
Architecture Design plans
Medical Devices Product designs
Defense Technical specifications

Any company that creates valuable engineering drawings should protect them.


What Types of Files Should Be Protected?

VeryDRM protects many engineering and technical file formats.

Software Common File Formats
AutoCAD DWG, DWT, DWF, DWS
Autodesk Inventor IPT, IAM, IDW, IPN
SolidWorks SLDPRT, SLDASM, SLDDRW
Siemens NX PRT
Solid Edge ASM, DFT, PAR, PSM
CATIA CATPart, CATProduct
Creo PRT, ASM
PDF Technical documentation
Microsoft Office Word, Excel, PowerPoint
Images JPG, PNG, TIFF

Companies often protect both CAD drawings and the supporting documents together.


Why Traditional Access Control Is Not Enough

Imagine this situation.

You upload a confidential AutoCAD drawing to SharePoint.

Only one supplier has permission.

The supplier downloads the drawing.

Now they can:

  • Save local copies
  • Email another company
  • Upload to Dropbox
  • Keep it after the project ends

SharePoint no longer controls the file.

VeryDRM does.


What Is Persistent File Protection?

Persistent protection means the security travels with the file itself.

Instead of protecting only the storage location, the file remains protected wherever it goes.

Whether someone stores it on:

  • USB drives
  • Personal laptops
  • Cloud storage
  • Email attachments
  • Backup servers

The protection remains active.


How VeryDRM Protects CAD Drawings

VeryDRM applies security directly to your files.

You stay in control even after files leave your organization.

Main Protection Features

Feature Benefit
View-only mode Prevent editing
Disable copying Stop copy & paste
Disable printing Prevent paper copies
Dynamic watermark Identify every viewer
Device authorization Limit approved devices
User authentication Only authorized users can open files
Expiration dates Automatic access expiration
Online permission check Instantly update permissions
Remote revoke Disable access anytime
Access logs Audit every file opening

Dynamic Watermarks Reduce Insider Leaks

One of the most effective security measures is dynamic watermarking.

Instead of showing only your company logo, VeryDRM can display:

  • User name
  • Email address
  • Company
  • IP address
  • Date
  • Time
  • Custom text

Even screenshots contain the watermark.

This discourages unauthorized sharing because every image can be traced back to the viewer.


Remote Access Revocation

Projects end.

Suppliers change.

Employees leave.

Contractors finish work.

Without DRM, they still keep your files.

With VeryDRM, administrators can revoke access immediately.

The next time someone tries to open the file, permission is denied.

No need to recover every downloaded copy.


Secure CAD File Sharing by Email

Email remains one of the most common ways to exchange engineering files.

Instead of sending unprotected attachments, protect them first.

Recipients can:

  • Open files after authentication
  • View only if authorized
  • Be prevented from printing
  • Be prevented from copying
  • Lose access automatically after expiration

Even forwarded emails remain protected.


Secure Engineering Files in Cloud Storage

Many organizations use:

  • Microsoft OneDrive
  • SharePoint
  • Dropbox
  • Google Drive
  • Box
  • File servers

These platforms manage storage very well.

However, downloaded files become independent.

Applying DRM before upload ensures protection remains active after download.


Protect Files Shared in Microsoft Teams and Slack

Engineering teams frequently exchange CAD drawings through collaboration platforms.

Without DRM:

  • Files can be downloaded
  • Forwarded
  • Saved permanently

With VeryDRM:

Every downloaded file continues enforcing your security policy.


Protect Files Exported from Internal Applications

Many companies have ERP, PLM, MES, or custom systems that export reports and drawings.

Instead of exporting plain files, organizations can automatically apply VeryDRM protection during download.

Users receive secure files immediately.

No manual work is required.


Audit Every File Access

Knowing who accessed what is just as important as blocking unauthorized users.

VeryDRM records:

Audit Information
User identity
Login time
Device
IP address
File opened
Success or failure
Permission changes

Security teams can quickly investigate suspicious activity.


Real Example

An automotive manufacturer shares gearbox drawings with three suppliers.

Supplier A finishes the project.

Normally, Supplier A still owns every downloaded drawing.

With VeryDRM:

  • Administrator removes Supplier A.
  • Previously downloaded files stop opening.
  • Remaining suppliers continue working normally.
  • Every access remains logged.

The company stays in control.
