Is there anyway to have different security settings based on culture for a single page?

I currently have a page that exists both in the UK and US culture, however I would like to have the UK page require a user/pass but have the US page publicly accessible. I noticed after creating the US page that removing the security settings in the US culture also removed it in the UK side.

I also noticed while looking for a backdoor method that kentico automatically redirects to the logon page before the page life cycle. Therefore the only method I found to work was to 'fake' a logon in the CS file for logon.aspx after doing a URL check (check for .com vs .co.uk and page name)

I don't find this solution very good, are there any better methods?
