Access Database Security in WebRoot

Our company has developed a product that lets you put databases on the web with a few lines of ASP Code. I know that if the database is stored within the webpage it is easyily downloaded by typing the URL in. Is there a way to prevent this. My Boss wants to keep this Access database within the web. We already have webs that use our product that keep the database in a differant location. But we are trying to look for a way this can be done within the web. I need all security concerns that can happen or what you think will happen.
