Secure CAD Projects While Designers Work at Full Speed
Designer PC → Local Workspace → Encrypted Server Storage → Authorized Access
Designers work on thier computer — in the office or remotely via VPN — while files remain encrypted on the server.
Works with AutoCAD, Revit, SolidWorks, and other CAD environments.
TeeraCryption changes how CAD projects are accessed:
-
TeraCryption provides CAD file encryption that protects engineering project files while allowing designers to work locally at full speed.
-
Encrypted CAD projects are copied and decrypted to a local workspace so designers can work at full speed without exposing files stored on the server.
-
Keep CAD project files encrypted on the server while designers work locally in a secure workspace—in the office or remotely via your existing VPN.
-
Designed for engineering teams that need to protect valuable design files and engineering intellectual property.
-
Developed by Engineers with over 35 years of experience in secure communication systems.

What is TeraCryption?
TeraCryption protects CAD project files directly on your server while allowing designers to open and work on them on thier own computers.
-
Files remain encrypted at rest.
-
Only authorized users can access them.
-
Designers continue working without any changes to their existing workflow.
TeraCryption is a file security platform that encrypts sensitive files, controls access, and eliminates the risks of traditional shared drives—without changing how users work.
Not Limited to CAD
TeraCryption is not limited to CAD projects.
Many organizations first evaluate TeraCryption for CAD projects, then expand its use across the organization.
Traditional shared drives expose files through network access and permissions. TeraCryption removes this exposure by keeping files encrypted on the server and allowing access only through authorized users. Users never access the server directly—only TeraKey, the authorized application installed on user devices, can retrieve and decrypt files.
This makes it possible to protect sensitive files across departments such as Legal, Finance, HR, and Operations using the same platform.
One platform. All departments. No workflow disruption.
Does This Look Familiar?
Many engineering teams store CAD projects on a shared server where engineers in the office work locally and remote engineers connect through VPN.
In this environment:
-
CAD files are slow to open when working over VPN.
-
Files stored on servers remain exposed when not in use.
-
Designers overwrite each other’s work.
-
External collaborators require full network access.
Most organizations accept these limitations because traditional encryption tools break CAD workflows.
But protecting engineering projects does not have to disrupt how designers work.

With TeraCryption
After the project is decrypted locally, designers work directly from their workstation instead of across the network.
Most engineering teams understand the architecture within the first 20 minutes.
Secure CAD Projects Without Changing the Workflow
TeraKey introduces a security architecture designed specifically for CAD environments.
When a designer opens a project:
-
Encrypted project files are copied from the server.
-
Files are decrypted locally into a secure workspace.
-
Designers work locally using their normal CAD applications.
-
When the work is finished, only modified files are encrypted and returned to the server.
Because the files are opened locally, designers experience the same performance as working with unencrypted files.
Works With Real Project Structures
Designers work at LAN speed because files remain local.
Engineering projects contain hundreds or thousands of dependent files.
TeraCryption encrypts each file individually.
-
Normal opening in CAD.
-
Multi-user access to project.
-
No checkout delays.
-
No remote session corruption.
Why Traditional CAD Protection Fails
Security platforms often force engineers to change how they work.
-
Slow opening assemblies.
-
Uncontrolled file locking conflicts.
-
Designer resistance to workflow changes.
-
Workarounds bypass security.
-
Continuous IT support tickets.
Security that interrupts engineering workflow does not survive in production environments.
Traditional Protection Moves The Work — Not The Security
Most CAD teams protect the connection (VPN), but not the project files themselves.
Traditional Environment | Result | With TeraKey |
|---|---|---|
Opening CAD files directly over VPN | Slow open, save, and regeneration operations | Designers work locally at full speed |
Uncontrolled file locking conflicts | Designers accidentally overwrite work | Controlled project access |
Files stored decrypted on servers | Ransomware exposure | Files remain encrypted on the server |
Freelancers require full network access | Security risk | Access limited to project files |
Large CAD projects accessed across the network | Continuous delays during work | Local decrypted workspace |
Traditional approaches protect the connection to the server, but the CAD files themselves remain exposed.
Protection Applied Directly To Files
Files remain on your server. Even if a file leaves the server environment, it remains encrypted and unreadable to unauthorized users.
When a drawing is saved:
-
Automatically encrypted.
-
Stored securely.
-
Opened normally by authorized users.
No retraining required.
Benefits for Engineering Teams
-
CAD project files remain encrypted on the server.
-
Only modified files are re-encrypted and uploaded to the server.
-
Designers work locally without VPN delays.
-
Engineering intellectual property stays protected.
-
Existing CAD tools and workflows remain unchanged.
-
Remote designers can work securely.
-
Ransomware attacks become a recovery procedure instead of a business shutdown.
Compatible With Existing CAD Tools
External references, folder structures, and project dependencies remain intact. TeraKey operates at the file-system level and does not require plugins or changes to CAD software. Designers continue working normally inside their applications. Compatible environments include:
-
AutoCAD
-
Revit.
-
SolidWorks.
-
Inventor.
-
BIM and XREF-based projects.

Ransomware Protection and Recovery
Even if a ransomware attack encrypts the server, engineering projects remain recoverable.
TeraCryption includes TeraBackup, a secure mirror backup component that continuously replicates encrypted project files to protected cloud storage.
This architecture allows organizations to restore operations without paying ransom.
Encrypted Files Remain Protected
All CAD project files stored on the server are already encrypted with TeraKey.
If attackers access the server or copy files:
• Files remain encrypted and unreadable.
• Intellectual property cannot be viewed or used.
• Sensitive engineering data remains protected.
Continuous Secure Backup
TeraBackup automatically mirrors the encrypted project repository to secure cloud storage such as:
• Amazon S3
• Microsoft OneDrive
• Google Drive
During normal operation:
• Modified encrypted files are automatically replicated.
• Only TeraKey encrypted files are transferred.
• All transfers occur through secure encrypted connections.
This creates a real-time mirror of the encrypted project storage.
Restore Operations Without Paying Ransom
If ransomware encrypts the server:
• The server can be rebuilt.
• TeraBackup restores the encrypted repository.
• All project files return to the TK-SERVER folder.
• Designers resume work immediately.
Because the backup contains already-encrypted files, the data remains secure even while stored in the cloud.
A ransomware incident becomes a recovery procedure instead of a business crisis.

Protect the CAD Files — Not Just the Network
Most engineering environments protect servers and network connections using VPN and access controls — but the CAD files themselves remain unprotected.
However, those protections do not protect the CAD files themselves.
Once a drawing is copied, downloaded, or stolen, storage permissions no longer apply.
TeraKey protects the file itself. Even if a file is copied outside the server, it remains encrypted and unreadable to unauthorized users.
Once IT managers see this architecture, they immediately understand why protecting the file itself is the only reliable way to protect engineering projects.
