First of all this is NOT a recomendation as such because its my wifes company.

Anyway a little while ago I was talking to my wife about hardware security, you know the sort of thing tft monitors, computer cages and the like. Well then another school I was talking to said they needed some monitor brackets, I suggested my wifes company, as we had been talking about this (they are an engineering company and as yet had not delt with anything like that) anyway 3 weeks down the road a protortype has been made and very nice it is too. They best thing is they are prepared to make bespoke products to suit your needs.

The Company is called H.I.T.S. Huffam IT Security and can be contacted on 01752 849118 ask for Verena or Brian and I'm sure they will only too pleased to help your specific IT security needs.
