"Royal Bank of Scotland, Nationwide and Balfour Beatty are outed as customers".

Why were they previously so bashful about it that it took this takeover to be outed? Or have you missed your t?

RBS and Nationwide as customers?

I think someone was looking at the wrong information. I am almost certain that they "used" to be customers, but have gone to a better company.....

You're wrong, they're all still customers :)

It appears i may have been a little hasty.

They are customers in many areas.....

I just presumed it was in a security perspective

They are security customers. Stop trying to spread FUD, it's a bit pathetic :)
