It works. If the contents of the confidentiality agreement comply with the law and both parties abide by it, the confidentiality agreement is valid. If one party violates the agreement, the other party can protect its rights and interests through legal channels. It should be noted that the confidentiality agreement is only a legal document, and it cannot completely guarantee the security of confidential information. If confidential information is leaked, both parties can pursue the responsibility through legal channels, but the leaked information cannot be withdrawn.
