Style and grammar corrected

Removed this 54-word sentence (30 words is about GOV.UK maximum) from the third 'problem' of point 4: 

For example, for a small-scale pilot deployment it might be reasonable to take the risk of using some unassured products, but to use the experience to discuss with the developer how they will provide independent assurance in the security functions their product provides, and to require this assurance to be in-place before wider roll-out.

What does it mean?
