This is a standard confidentiality agreement where both parties will be disclosing confidential information to each other. It need not be the same type of information that is being disclosed, as long as both parties are disclosing information that they consider to be a trade secret and/or something that would not be publicly discoverable in any form.
If you want to share confidential information with someone else outside your business, a non-disclosure agreement (or NDA) is a good way to ensure that the person you share the information with fully understands how important it is to you. A good NDA will set out clearly what they can and cannot do with what you tell them and crucially, it requires them to contractually agree that they will protect the confidentiality of that information. Confidential information is anything that a member of the public wouldn't know or be able easily to find out.
If you will be the only party disclosing confidential information, (which might be the case, for example, where you are considering appointing another business or individual as an agent or to provide you with advice), you should use our standard confidentiality agreement (one-way) template, unless you want something very 'light touch', in which case take a look at our simple confidentiality agreement (one-way) in case it may suit you better.
