Confidentiality agreement: What it is, types and how to write it


What is a confidentiality agreement and what is it for
Confidentiality agreement is a legal document through which one or more parties undertake not to disclose sensitive information to third parties.
This type of agreement is essential to protect strategic data, intellectual property, trade secrets, or any other valuable information within a company.
It is commonly used in labor relations, business agreements, innovation projects and other environments where confidential information plays a key role.
EXAMPLE: A technology company that hires a new developer can make him sign a confidentiality agreement to prevent him from sharing information about the projects he works on.
Difference between confidentiality agreement and confidentiality clause
Although they are often confused, a confidentiality agreement and a confidentiality clause are not the same thing:
EXAMPLE: An employment contract may include a confidentiality clause, while a company that collaborates with another on a project may sign a separate confidentiality agreement.
Types of confidentiality agreements
There are different types of confidentiality agreements depending on the number of parties involved and the purpose of the contract.
1. Unilateral confidentiality agreement
In this type of NDA, only one of the parties undertakes not to disclose information. It is common in employment relationships and hiring.
EXAMPLE: An employee who accesses sensitive company data signs an NDA to not share that information with third parties.
2. Bilateral confidentiality agreement
Here, both parties are committed to maintaining confidentiality. It is used in business collaborations and strategic agreements.
EXAMPLE: Two companies that are developing a product together agree not to disclose the details of the project.
3. Multilateral confidentiality agreement
It involves more than two parties, all with an obligation to protect confidential information.
EXAMPLE: A consortium of companies working on a joint project to develop new technology.
