This study aims to review; 1) What aspects need attention in making agreements to keep company secrets?; 2) What is the significance of an authentic Deed in making an agreement keeping company secrets?. The research method used is evaluative descriptive research. Evaluative research is basically centered on final recommendations that affirm that an object of evaluation can be maintained, improved, improved or even dismissed in line with the data obtained. The results showed that; 1 The most that companies do to keep company secrets is done by making written agreements between the company and employees within the company and outside parties with an interest in the company. 2) The tendency to choose the Company's form of protection is at least based on two reasons, including the following: First, because often the substance that is desired to get protection is something that cannot be patented, such as the company's customer list, financial data, business notes and others. Secondly, it is also possible that what wants to be protected is actually possible to be granted a patent, but inventors prefer this form of trade secret protection for various reasons such as unlimited protection periods, more guaranteed confidentiality values, high fees at patent offices and complicated registration formalities
