If you want to function as an entrepreneur in information security, you will either be an information security practitioner who wants to launch a company, or you are already an entrepreneur and want to move into a more lucrative field. If you are the former, odds are that you understand a core problem and have a good solution in mind. You may need funding to create a proof-of-concept device or application. You may already have that and need help finding customers. You may just have a rough idea that you want to be your own boss and nothing beyond that. In all of these cases, the key is to find a partner.
