French to English Bus/Financial Business/Commerce (general) information security

I'm translating the programme for a conference on information security in Europe intended for companies. This terms appears in the name of one of the groups of talks taking place (the names of the individual talks are also listed below for context).

I am aware of the most common translations for the verb maitriser (control/master etc.), but none of them seem to fit here. Could "use" be an possible translation: "...used incorrectly by companies" ? I'm really not sure how to translate this correctly and in a sufficiently snappy way (given that this is the title of a group of talks):

Many thanks in advance.
