Dear friends,

(Left., until now, to odd, low-level IT staff to put right, and seen as a concern only of data-rich industries such as banking, telecoms and air travel, information protection is now high on the boss’s agenda in businesses of every variety.)

According to my understanding, the author first mention that information protection is only a concern of data-rich industries until now. "Until now" includes "now", right? But why does the author later says that now information protection is a big concern of all kinds of businesses? They are contradictory.

A million thanks.

until now means 'before now'. It doesn't include 'now' this moment.

Until now - until this point in time. Now - at this point in time.
