Protect Your Core Designs
In the field of engineering design, SOLIDWORKS files carry a company’s most valuable intellectual property. Traditional data loss prevention methods often fail to secure complex CAD files: relying solely on file type recognition or content fingerprinting is ineffective, while strictly restricting USB or network access can disrupt engineers’ workflows.
