Be that as it may, this raises some very concerning questions for all of those in business – the most important being: what are the chances this could happen to us?

Let’s be clear – what we are talking about here isn’t just someone searching for you on Google and ending up at the Website of someone based overseas with a similar name as you. What has resulted in this situation is the potential for full disclosure of private and confidential details of clients – some of whom may never trust that business again.
