iOS 7 comes with solid additions for education and business users, and Fraser Speirs offers a good explanation of one of them, Web Filtering:

This feature impacts schools at a number of levels. While I don’t think it will allow schools to ditch the filtering on the school network, I think it will allow some relaxation of policy.

For schools that have disabled Safari in favour of some janky third-party filtered browser, it’s now feasible to allow Safari again. Similarly, schools which have implemented policies banning apps with embedded web views, that policy too can be relaxed since the filtering applies there too.
