This should be a resounding success
Well, as much of a success as anything else commercial that GCHQ turns it's hand to. There's a problem in that the spooks don't understand business or even the need to provide a service that customers want. The wheels have fallen off their other attempts at supporting and getting involved in business.
For example they started their accredited advisor scheme with a fanfare and a desire to get the best of industry and the best of government working together. A praiseworthy objective but they struggled to support the scheme and often refused to listen to the same people that they had selected as the "best of the best". That resulted in them binning the scheme. One of the many headaches with that initiative was that CESG didn't want to give the advisers either authority to make decisions or provide the advisors and industry with information. GCHQ takes in information, it's not good at giving it out.
