If i understand it correctly, CVT only encrypts a document, it does not encrypt a network.

If someone was looking to protect their payments network, as an example, then CVTwould not be suited to this.

If someone was looking to protect all confidential correspondence then CVT is the best option.

So, if someone was to hack Walmart again and try to obtain the Credit Card info, would CVT have stopped this?

My thinking is that a company may spend a lot of money to protect the network but then also spend a little more to further encrypt the individual files. CVT gets a smaller piece of a lot of pies but is not the go to solution in that instance?

Just thinking out loud.
