Whether or not your organizations data as valuable to outsiders depends heavily on what business you’re in.
Generally said, your organizations data is valuable :period.
There is an ever increasing amounts of data being taken from paper, and digitized.
Therefore they are not only victim to attempts of corporate espionage, but also to data collection spies, And even more persistent threats.
While ago I worked on a case of CEO Frade, in which the main enabler was the fact that the email server of the organization had a vulnerability, which was exploited, and allow the perpetrators to monitor email communication between the chief executive officer, and The chief financial officer.
This angle was then exposed by the attackers to lose a couple of million euros; unretrievable.
So you see, it’s not only corporate espionage that as a threat of valuable information, but much less appearing information can be utilized to harm your organization.
