Why Do Subcontractor Risks Exist in CAD File Sharing?
The complexities of modern supply chains demand data sharing across multiple tiers. When subcontractors, or their subcontractors, access your CAD files, control often becomes impossible.
Here is why the risks become unavoidable:
Here is why the risks become unavoidable:
- Lack of visibility: Companies lose the ability to track who manipulates or forwards CAD files after first-level access.
- NDA limitations: Legal contracts like NDAs do not cover downstream subcontractors effectively. Learn why NDAs are insufficient for securing CAD files.
- Weak device security: Remote subcontractors may rely on unprotected devices, creating easy entry points for IP theft.
- Unauthorized sharing: The more entities involved in your subcontractor ecosystem, the greater the likelihood of unauthorized file transfers.
Three Proven Strategies to Mitigate Subcontractor Risk
1. Implement CAD File Encryption
File encryption ensures your CAD designs remain secure, even if shared unknowingly. Solutions like HaloCAD integrate encryption directly within CAD file layers. These encrypted files are tamper-proof, meaning that unauthorized entities cannot access core design elements. Secure sharing platforms for CAD files often utilize blockchain technology to provide audit trails and enforce transfer controls.
2. Use Blockchain-Based Ownership Proof
Blockchain certificates provide indisputable proof of ownership and authorship of CAD files. With systems like CADChain’s BORIS plugin, engineering firms can establish tamper-proof records of CAD file creation and access events.
Why it works: Blockchain creates immutable logs of any alterations, access, or transfers involving CAD files. This not only protects ownership but also ensures legal enforceability in cases of disputes.
