"I probably tend to believe that there's a lot of employees that are already doing it and they're probably doing it without permission, which is even scarier. I think we have to be very cautious about being overly cautious, because sometimes I think we set a conservative attitude and our employees, contractors and customers are going to want to be at the cutting edge of technology," she said.
"BT is an old company and we have a lot of people there with a lot of tenure. So we fight that attitude. I think we have to be careful, very large organisations that aren't bringing in the young innovative mind-sets into IT and security are going to struggle with adapting to that after it has already peaked in the field. That's where we are today, we are chasing it a little bit."
She added: "We have found instances of people using Google and different cloud services without going through the proper process and creating compliancy issues for us. We are struggling with that and overly conservative in some areas. It's probably because we are so large and the compliancy issues are so broad for us that we tend to take a very European view of some of the issues at hand right now."
