Intercept X for Mobile Apple iPhone

Hello

I have a question about Intercept X for Mobile or Mobile Threat Defense. When using Apple iPhone, is the web and URL filter and the control of unsafe downloads and links in real time also available in the free version of Intercept X for Mobile? Because the data sheet (assets.sophos.com/.../sophos-intercept-x-for-mobile-dsde.pdf) says something about “iOS-enabled devices required”.

What does this mean?

Thanks
