Adding product to shopping cart not working when browser security level in HGH

If philtem is correct, and he seems to be, then it has nothing to do with CI. That would happen on any site, shopping or not, that used cookies.

On High Security, IE:
Allow persistent cookies: Disabled
Allow per-session cookies: Disabled
Allow third-party persistent cookies: Disabled
Allow third-party session cookies: Disabled

It also disables javascript and a number of other things on the highest security setting.

If you go into firefox or chrome or whatever and disable cookies, the same thing will happen. The only way to maintain a persistence state if cookies are disabled is to pass the session id through the url on each request, which is not how CI is designed to work. Most websites that rely on cookies state that the site won't work properly unless cookies are enabled.
