As a general rule, a confidentiality agreement stipulates that the recipient undertakes not to disclose or use the information shared intentionally or unintentionally. Exclusions from the agreement also include materials that are public knowledge and information that the recipient has already developed or transmitted to them. For example, a start-up looking to raise money from venture capitalists or other investors might fear that their good idea will be stolen instead of receiving an investment. A signed NOA legally excludes such theft of ideas. Without any, it can be difficult to prove that an idea has been stolen. A multilateral NOA can be beneficial insofar as the parties concerned only re-examine, redevelop and implement it. This advantage can, however, be offset by more complex negotiations, which may be necessary to enable the parties concerned to reach a unanimous consensus on a multilateral agreement. What really amazes me is that most brands never go back to an NDA until we introduce it to them. « We always require marketing partners to sign a confidentiality agreement before they give access to our site, email list, social media accounts and advertising accounts. We spend a lot of time and money building these assets and an NDA helps protect them, » says Cliff Sneider, CEO of Beds Online. A confidentiality agreement can protect any type of information that is not known to all.
However, confidentiality agreements may also contain clauses protecting the person receiving the information, so that if they legally receive the information through other sources, they would not be required to keep that information secret.  In other words, the confidentiality agreement generally requires that the receiving party process confidential information only if that information has been transmitted directly by the publishing party. However, it is sometimes easier to get a recipient party to sign a simple agreement, which is shorter, less complex and does not contain security rules to protect the recipient. [Citation required] A multilateral NOA involves three or more parties, of which at least one of the parties expects to disclose information to other parties, and requires that such information be protected from further disclosure.
