Prototypes manufacturing industry will inevitably involve customer product R&D of highly confidential information, therefore the suppliers' confidentiality measures are in place becomes the most concerned problem for every single enterprise. JHmockup has developed a strict internal daily confidentiality system to strengthen the confidentiality awareness of employees and regularize the practice.Normally an official NON-DISCLOSURE AGREEMENT(NDA) agreement will be signed by sides in prior to kick off the project. All our workshops and offices adopt an advanced access control system to strictly control the access of all personnel. All computers and communication devices and networks are strictly monitored by the system, and the internal and external networks are completely isolated. External personnel can only see the products commissioned by their own companies in designated places, and internal employees have no way to disclose customer information. There are a number of special confidential sample workshops, for customer who want to track the personal design models will have a special confidential room card, others can not enter, which completely ensures that any confidential content for customers will not be disclosed to the third party.
