Based on the information available, it's challenging to accurately define the target audience. The lack of HTTPS suggests the target audience may be individuals who are less concerned about security or those using the website for non-sensitive purposes. The warning message implies that the site might be more appropriate for use on trusted networks (like home or work Wi-Fi), suggesting the target audience might be individuals who primarily access the site from these locations. Without more information about the nature of the business, it is difficult to ascertain the target audience. However, since the security warning is a significant barrier for users, the target audience could be the users that are not easily discouraged by basic security warnings and are not providing sensitive data into the website.
