Microcosm security issues?

I can't access those links at Islington Council at present. I will make enquiries with IT. I understand council IT departments can lift bans on sites on a case by case basis.

I just invented both of those URLs, at this second they both do nothing and will result in a DNS error.

But the gist is... every site will have it's own domain, and any domains whitelisted would usually affect the subdomains too, so it's possible to make Microcosm appear on any existing whitelisted site without needing to change ICT policies.
