@croydon - The thing is, it is very difficult to completely safeguard your data because it is still subject to human error. The best management system in the world would have trouble with that, particularly if it was very large, and so needed a lot of people to have access to it.
One of the ways hackers manage to get passwords is by calling up a staff member and pretending to be the boss, or something similar and just asking for it over the phone. In a huge company people are never going to know every voice.
Which is why data management solutions can't just be about storing the information. They also have to cover protecting it as well.
